Executive summary
The purpose of the Pinnace Channel Aquaculture Fisheries Reserve Management Plan (hereafter also referred to as 'the Plan') is to specify the policies and strategies for managing activity within the Pinnace Channel Aquaculture Fisheries Reserve (PCAFR).
The Plan has been prepared under the requirements of the Fisheries Act 1995 (the Fisheries Act) and has been developed in accordance with Ministerial guidelines. The Plan prescribes management arrangements for the PCAFR within a framework of Ecologically Sustainable Development (ESD).
The PCAFR is a greenfield site for marine aquaculture that has the potential to support significant expansion of the existing marine aquaculture sectors within Port Phillip Bay (PPB), in particular blue mussels and other bivalve shellfish. The PCAFR consists of two 500 ha blocks located on either side of the Pinnace Channel where it flows northwards from the Great Sands area in southern PPB.
The PCAFR was declared as a fisheries reserve under the provisions of the Fisheries Act on 6 March 2003.
The scope of the Plan is limited to the PCAFR and its immediate environs. The Plan is also constrained by the provisions of the Fisheries Act; the Victorian Government response to the recommendations of the Environment Conservation Council (ECC) in the final report of their Marine Coastal and Estuarine Investigation (2000); the Ministerial guidelines issued in respect of the preparation of the Plan; and other legislation and policy.
The vision of the Plan is:
'the development of environmentally sustainable, economically viable and socially equitable marine aquaculture at the PCAFR that contributes a significant commercial supply of high quality seafood.'
To assist in achieving this vision, the Plan has four goals:
- maintenance of the ecological sustainability of the natural resources being utilised;
- the development and growth of an efficient, effective and economically viable aquaculture industry;
- management of the PCAFR, reflecting the expectations of other users of the marine environment; and
- clear, transparent and cost-effective management.
The Plan prescribes a range of ecological, economic, social and governance objectives and strategies that reflect the goals of the Plan. To achieve these objectives, the Plan prescribes comprehensive performance indicators, reference points and management triggers.
The Plan also prescribes a suite of management actions including:
- aquaculture licensing arrangements including the development of classes of aquaculture licences specific to the PCAFR;
- Crown leasing arrangements for the PAFR consistent with the Victorian Aquaculture fisheries reserves - leasing and licensing policy;
- an environmental management framework including baseline surveys to be undertaken by the Crown lease holders, an ongoing monitoring program to be undertaken by the aquaculture licence holder, and auditing and reporting requirements;
- the requirements for compliance with the relevant translocation guidelines;
- the extension of the Victorian Shellfish Quality Assurance Program to include the PCAFR;
- the use of active feeding of artificial feeds subject to demonstration that such feeding meets the requirements of the State Environment Protection Policy (Waters of Victoria) 2003 (SEPP)and is consistent with the Port Phillip Bay Environmental Management Plan 2002;
- no commercial culture of finfish for the life of the Plan;
- general public access to the PCAFR;
- restrictions on non-aquaculture activities within the PCAFR;
- the requirement for Fisheries Victoria, Department of Primary Industries (DPI) to survey and provide navigation marking for the PCAFR, and the requirements for Crown leaseholders to survey and provide navigation marking for Crown leases within the PCAFR;
- uniform requirements for size, shape and colour of surface infrastructure, and provisions for attachment;
- the development of industry codes of practice addressing noise and lighting, and waste management;
- a maximum allocation of 50% of the PCAFR for bivalve shellfish aquaculture and a maximum of 500 m of longline backbone per ha;
- development rates will be determined by Fisheries Victoria in consultation with the relevant stakeholders on a case by case basis, and with reference to their development plan;
- establish a research and development site within the PCAFR, and preparation of a three year research and development action plan for the PCAFR;
- a requirement that holders of Crown leases within the PCAFR hold public liability trespass insurance to a minimum value of A$10 million; and
- a requirement that holders of Crown leases provide a bond or bank guarantee for the removal of aquaculture equipment.
Other issues covered in the Plan include:
- the reporting of exotic marine organisms and disease;
- production reporting for the PCAFR;
- a process for designing the lease dimensions and orientation within the PCAFR; and
- ownership of stock on the seafloor.
The Plan will provide the basis for the management of the PCAFR for a period of three years and, prior to its expiry, it will be reviewed.
Implementation of the Plan will require actions by Government in respect of certain policy matters, by Department of Primary Industries in respect of day-to-day management, and by other stakeholder entities. To this end the Plan includes a detailed implementation section addressing key actions of the Plan.
Introduction
The purpose of the Pinnace Channel Aquaculture Fisheries Reserve Management Plan ('the Plan') is to specify the policies and strategies for managing activity within the Pinnace Channel Aquaculture Fisheries Reserve (PCAFR).
The Plan prescribes management arrangements for the PCAFR that provides for a significant commercial supply of high quality seafood within a framework of Ecologically Sustainable Development (ESD).
The Plan has four goals:
- maintenance of the ecological sustainability of the natural resources being utilised;
- the development of an efficient, effective and economically viable aquaculture industry;
- management of the PCAFR, reflecting the expectations of other users of the marine environment; and
- clear, transparent and cost-effective management.
The Ministerial guidelines for the preparation of the Plan were published in the Victoria Government Gazette on 31 July 2003 and are shown in Appendix 1.
To assist the reader, a list of acronyms and abbreviations used throughout the text is provided in Appendix 2 and definitions for terms are provided in Appendix 3.
The implementation of the Plan will be facilitated by the development of policies and tools.
Overview of offshore marine aquaculture in Port Phillip Bay
The aquaculture industry in Port Phillip Bay (PPB) has been established for around 25 years, with longline culture of blue mussels (Mytilus edulis) the predominant activity. The blue mussel is a filter feeding bivalve shellfish found throughout southern Australia. Victorian blue mussels are renowned for their tender flesh and delicious flavour.
In 2003/04 the Victorian mussel aquaculture industry, based in PPB and Western Port, produced approximately 1100 tonnes of mussels, worth over $3.1 million, and is the largest mussel production industry in Australia. Mussel farming is predominantly based on natural settlement of spat, with spat collection undertaken in PPB during winter. In 2002, hatchery production of mussel spat in Victoria was undertaken for the first time and these spat are currently ongrowing in PPB.
Mussels are harvested after 15-18 months growout on longlines, and fetch between $1.80-2.50/kg wholesale. Most product is harvested for human consumption and sold live in the shell on the domestic market. However further processing and value-adding, including smoked, marinated and vacuum packed product is being investigated by the industry. Some mussels are produced for bait and spat only.
Mussel aquaculture is currently undertaken in designated harvesting areas within PPB, including large areas at Grassy Point and Clifton Springs, and smaller areas at Beaumaris and Dromana. Individual licence sites1 are generally 3 ha. A range of growing locations and conditions allows for almost year-round availability of mussels, and site diversity helps protect growers from the effects of nuisance algal blooms. Currently within PPB there are 22 aquaculture licences authorising harvest for human consumption from sites totalling 126 ha, and one aquaculture licence and one general permit authorising harvest for bait or spat from two 3 ha sites (Table 1).
Cage culture2 of abalone (Haliotis rubra, H. laevigata and hybrids) within PPB has also been undertaken. This form of aquaculture is in the experimental or developmental phase and significant commercial production has not yet been realised.

Government approved recommendations of the Environment Conservation Council's Marine Coastal and Estuarine Investigation
A major factor identified as limiting marine aquaculture development in Victoria was a lack of access to suitable sites in marine waters. To address this and other issues, the Environment Conservation Council (ECC), at the request of the Victorian Government, completed an investigation of the State's marine, coastal and estuarine areas. Following extensive research, consultation and consideration of environmental, social and economic implications, the ECC prepared recommendations on a system of marine protected areas and areas suitable for marine aquaculture in their final report (ECC 2000).
In their final report the ECC recommended 12 marine aquaculture zones, including two land based zones, in areas that have demonstrated successful aquaculture performance or growth of target species in the past or, on advice from Fisheries Victoria and industry, would be suitable for target species. The zones total 2682 ha including 983 ha of currently farmed area. The ECC also recommended each aquaculture area be subject to preparation of a management plan. It was noted by the ECC that sites within the recommended marine aquaculture zones not be allocated prior to the development of management plans (recommendation 41). The Victorian Government has endorsed all the recommendations of the ECC for marine aquaculture, including the 12 marine aquaculture zones.
The Victorian Government response to the recommendations of the Final Report of the ECC's Marine Coastal and Estuarine Investigation (2000) for marine aquaculture is provided in Appendix 4.
Pinnace Channel Aquaculture Fisheries Reserve
Development of the Pinnace Channel Aquaculture Zone (recommendation E11, ECC 2000) has been given the highest priority of the government endorsed aquaculture zones. The Pinnace Channel Aquaculture Zone was declared as a fisheries reserve by Order in Council in accordance with section 88 of the Fisheries Act on 6 March 200Under the Fisheries Act a management plan must be prepared in respect of a fisheries reserve as soon as possible after the fisheries reserve is declared.
The PCAFR is a greenfield area with no current commercial aquaculture activity although some research has been undertaken in the fisheries reserve.
Previous information on aquaculture activity in PPB generally provides background to the aquaculture activity likely to occur within the PCAFR.
Attributes of the Pinnace Channel Aquaculture Fisheries Reserve
A detailed description of the attributes of the PCAFR is provided in Appendix 5; a summary of that description is provided in this section.
Location
The location of the PCAFR is shown in Figure 1.
PCAFR is comprised of two 500 ha blocks (approximately 1.7 km by 2.8 km each) located on either side of the Pinnace Channel where it flows northwards from the Great Sands area.
The blocks are referred to as the northern and southern blocks and the coordinates are as follows:
Northern block | ||
---|---|---|
Datum GDA94 (Degrees and decimal minutes) | ||
South | East | |
North West | 38°14.257' | 144°48.864' |
North East | 38°13.910' | 144°49.979' |
South West | 38°15.693' | 144°49.581' |
South East | 38°15.347' | 144°50.697' |
Southern block | ||
Datum GDA94 (Degrees and decimal minutes) | ||
South | East | |
North West | 38°16.573' | 144°50.061' |
North East | 38°16.226' | 144°51.177' |
South West | 38°18.010' | 144°50.779' |
South East | 38°17.663' | 144°51.895' |
The site location allows adequate separation from:
- major shipping activity; and
- the Port Phillip Heads Marine National Park (at the closest point the separation distance is 3.1 km).
Bathymetry and sediment characteristics
Water depth in the blocks generally ranges from 15 to 24 m. The predominant sediment consists of sand and mud, and becomes muddier and of smaller mean grain size with increasing depth. The mud content of the sediment ranged from approximately 8 to 40%. Sandy, shallower areas at depth less than 20 m displayed a bedform dominated by mounds and depressions caused by callianassid shrimps, while the muddy sediments of depth greater than 20 m displayed a flat profile. Sediment carbon and nitrogen contents ranged from 1.4 to 5.6% and 0.06 to 0.19% respectively.
Figure 1: Pinnace Channel Aquaculture Fisheries Reserve
Benthic fauna, epifauna and epiflora
The benthic fauna of PCAFR consists of many species represented by relatively few individuals found in one or two samples. Polychaete worms dominated. Other relatively abundant species are the crustacean Kalliapseudes sp. and the bivalves Chioneryx cardiodes and Corbula gibba (an exotic bivalve). Species diversity and density decreased with depth.
Abundance of epifauna is generally low with less than 10 individuals per 100m (transect). The ascidian Pyura stalonifera was the most common species, followed by the native flat oyster, the ascidian Cnemidocarpa etheridgii and the scallop. Sparse Caulerpa sp. beds along with beds of an unidentified red alga are found at a depth of 20m or less.
Currents, wind and waves
Both blocks of the PCAFR are subject to daily tidal flushing that generates considerable mixing and exchange of water. Current directions vary from the north to northeast on the flood tide, and from the northwest to south-southwest on the ebb tide. Peak currents generally range from 0.10 to 0.25 m/s.
The predominant wind direction in southern PPB is from the south. The most common wind speed range was 20-30 km/h followed by the 30-40 km/h, 11-20 km/h, greater than 40 km/h, and 10 km/h or less.
Wave modelling, and data from the adjacent Rosebud area, (Mornington Peninsula) indicates the predominant wave height at the PCAFR is likely to be between 0.5 and 1.0 m, with waves greater than 1.0 m occurring less than 8% of the time.
Water quality
Water temperature in the PCAFR is predominantly between 10 and 22°C. Salinity in the PCAFR generally ranges from 30 to 36 parts per thousand.
The southern end of PPB generally has lower levels of chlorophyll a reflecting a lower concentration of phytoplankton in the area. However, good currents in the region may assist nutrient availability to shellfish. The high flushing rates and high exchange with Bass Strait water is considered to decrease the risk of harmful algal blooms within the PCAFR.
There is little risk of contamination by faecal coliforms from land based sources within the PCAFR.
Access and serviceability
The ports, infrastructure and provisions detailed in Table 2 are potentially available for industry to service the PCAFR.
Overview of aquaculture activity in the Pinnace Channel Aquaculture Fisheries Reserve
At present there is no commercial aquaculture activity within the PCAFR. Aquaculture research and development in the PCAFR, conducted by Fisheries Victoria in association with the Primary Industries Research Victoria Queenscliff Centre, (PIRVic, formerly the Marine and Freshwater Resources Institute) and industry, has included the experimental collection of scallop spat and the growout culture of scallop on both bottom and sub-surface longlines. The growout culture of akoya pearl oyster on sub-surface longlines and mussels on surface longlines is also being investigated. This research has indicated strong potential for expansion of commercial culture of bivalve shellfish into the PCAFR.
Other research conducted in PPB relevant to the PCAFR includes suspension culture of native flat oyster and the development of translocation protocols for mussels to prevent the spread of exotic organisms.
Other users of the Pinnace Channel Aquaculture Fisheries Reserve and environs
Other current and potential uses of the PCAFR and environs include:
commercial shipping;
recreational boating, fishing and diving;
charter boat operators; and
commercial fishing.
Commercial shipping
Port Phillip Bay is one of Australia's largest ports for national and international shipping and has defined routes for the movement of large commercial vessels within PPB to either Melbourne or Geelong. All vessels with a depth greater than 4-5 m that enter PPB must travel via the South Channel. After traversing the South Channel, vessels destined for Geelong turn at the Hovell Pile and proceed north-west to the Prince George Beacon. The shipping fairway, defined by a line between Hovell Pile and Prince George Beacon, is in close proximity to the northern block of the PCAFR. Fisheries Victoria, following consultation with the Victorian Channels Authority, will provide navigation marking off the northern block of the PCAFR to ensure clear separation of the PCAFR from commercial shipping activity. A notice to mariners indicating the location of the site and associated navigation infrastructure will be issued.
Recreational boating
The PCAFR and its surrounding waters are used for recreational boating, though the number of individuals that utilise the area is low when compared to other areas of PPB. The area is used for a small number of yacht races in the vicinity of the Mud Islands and down the Pinnace Channel. Boats also use the Pinnace Channel as a route to connect the South Channel and central PPB. The Pinnace Channel is 5.5 m deep and is situated approximately 1.3 km to the south-west of the PCAFR. A separation distance of approximately 1.8 km between the two blocks of the PCAFR provides a corridor for the continued use of Pinnace Channel by recreational boating.
Recreational fishing
Recreational fishing is regarded by many in Victoria as one of the most important uses of PPB. The key recreational species in southern PPB are sand flathead (Platycephalus bassensis), southern calamari (Sepioteuthis australis), King George whiting (Sillaginodes punctata), southern sea garfish (Hyporhamphus melanochir) and snapper (Pagrus auratus). Productive snapper grounds are located in the vicinity of the PCAFR. The PCAFR is approximately 7.5 km from the nearest shore and does not contain fishing areas that are unique in PPB.
Recreational diving
Recreational diving is common throughout PPB with divers taking part in a range of activities including reef dives, wreck dives, photography, environmental monitoring, marine mammal viewing dives and collection of fish and shellfish. The PCAFR has limited appeal to recreational divers due to its lack of reef or unique substrate and its distance from shore. A possible attraction to recreational divers is the scallop beds located at or near the PCAFR, however the reserve is considered deep (16-25 m), and the scallop abundance is generally low, compared with other scallop beds in PPB. As a result, recreational divers do not generally use the PCAFR for scallop collection.

Table 2: Ports and infrastructure detail potentially available for industry to service the PCAFR
Charter boat operators
The charter boat industry in PPB provides recreational fishing, aquatic mammal viewing and diving services. The nature of the environment within the PCAFR and the relative absence of aquatic mammals in this area suggest that the PCAFR is not a major charter boat destination at the present time. It should be noted, however, that the infrastructure to be developed for commercial aquaculture within the PCAFR may attract fish, leading to an increased use of the area by charter boats in the future.
Commercial fishing
Victoria's bay and inlet fishery provides seafood year round valued at over $7 million annually (2003/4). One of the key bay and inlet fisheries occurs in PPB with an average annual value of $3 million (2000-2004). The key species (and the average annual landed value between 2000-2004) caught in PPB are King George whiting ($849,000), southern calamari ($419,000), pilchards ($291,000), snapper ($480,000) and southern anchovy ($258,000). These five species account for almost 80% of the PPB catch based on value.
Information on the PPB fishery is recorded and published by Fisheries Victoria. The catch and effort data are recorded for different areas of PPB based on grids. The PCAFR brackets four reporting grids. These grids total approximately 260 square km. The average annual commercial fishing catch value (2000-2004) within the grids was $263,000, made up predominantly of pilchards at 37%, King George whiting at 14%, snapper at 14% and southern calamari at 12%.
The PCAFR covers approximately 4% of the four reporting grids described above. The majority of the PCAFR is located in grid F7, which produces an average annual catch (2000-2004) of $92,000. The predominant species caught in this grid is pilchards which are caught using purse seine nets. These nets are often set close to the banks and the mouth of the channels within the Great Sands area.
The PCAFR is located in deeper waters that are not traditionally used for whiting fishing. Furthermore, the PCAFR occupies a small percentage of the existing commercial fishing grounds for southern calamari and snapper. The other species caught within the 4 grids are of low economic value and a reduction of 4% of their fishing area will have little or no impact on catch rates.
Current management arrangements
The term aquaculture is generally used to describe all types of aquatic farming, whether in fresh, brackish or seawater. The Food and Agriculture Organisation (www.fao.org/fishery) defines aquaculture as:
'… the farming of aquatic organisms, including fish, molluscs, crustaceans and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding and protection from predators.'
Legislative framework
A range of Government legislation and policies are relevant to aquaculture. The key Victorian legislation in regard to aquaculture development in offshore areas includes:
- Fisheries Act 1995;
- Coastal Management Act 1995;
- Land Act 1958; and
- Environment Protection Act 1970.
Fisheries Victoria is the lead agency in aquaculture development in Victoria and operates in accordance with the relevant objectives of the Fisheries Act:
'to provide for the management, development and use of Victoria's fishery, aquaculture industries and associated aquatic biological resources in an efficient, effective and ecologically sustainable manner'; and
'to promote sustainable commercial fishing and viable aquaculture industries and quality recreational fishing opportunities for the present and future generations'.
To deliver on these objectives Fisheries Victoria provides the core functions of licensing, administration, policy development and management planning. In addition, Fisheries Victoria provides resources for research and development, regional extension, fish health management and shellfish quality assurance.
The purpose of the Coastal Management Act 1995 (the Coastal Management Act) is:
- to provide for coordinated strategic planning and management for the Victorian coast; and
- to provide a coordinated approach to approvals for the use and development of coastal Crown Land.
The Land Act 1958 (the Land Act) provides for the granting of leases and licences for the use of Crown Land. Section 134 of the Land Act provides for the issue of leases for non-agricultural purposes (for example aquaculture). Section 134 leases provide exclusive occupancy rights.
The Environment Protection Act 1970 (the Environment Protection Act) makes provisions for 'the protection of the environment'. Accordingly the Environment Protection Act provides for the regulation of discharge of waste into the environment, the prevention and control of pollution and noise, the protection and improvement of the quality of the environment, and specification of standards and criteria for the protection of beneficial uses (including aquaculture).
Aquaculture fisheries reserves
The Victorian Government has jurisdiction over marine aquaculture within the State's waters. The Government has endorsed zones within the estuarine and marine waters of Victoria for aquaculture development. These zones correspond with the zones recommended for marine aquaculture by ECC in the final report of their Marine Coastal and Estuarine Investigation (ECC 2000). The ECC noted it was expected these zones be established as fisheries reserves under section 88 of the Fisheries Act. The zones have been declared as fisheries reserves for the purposes of aquaculture and management plans are to be prepared for each fisheries reserve under Part three of the Fisheries Act.
Authorisation required to undertake aquaculture
Aquaculture activity is authorised by aquaculture licences issued under the Fisheries Act. An aquaculture licence gives an aquaculturist the authority to conduct aquaculture activity in a specified area (the licence site) for a specified period.
Aquaculture licences list the specified area, specify the species of fish (as defined under the Fisheries Act) that may be farmed, the licence period (generally 12 months), harvesting restrictions and quality assurance programs, production return requirements, operational management controls and environmental management provisions.
For the purpose of the Fisheries Act an aquaculture licence is a prescribed class of renewable and transferable fishery licence. The Fisheries Act currently prescribes classes of aquaculture licences that may specify Crown Land including: Aquaculture (Crown Land - Other), Aquaculture (Crown Land - Bivalve Shellfish), and Aquaculture (Crown Land - Abalone) Licence.
An Aquaculture (Crown Land - Other) Licence authorises the licence holder, on the Crown Land and in or on the protected waters covering that land specified in the licence:
- to use, form or create a habitat for hatching, rearing, breeding, displaying or rowing fish (other than bivalve shellfish for human consumption, abalone or eels) or fishing bait specified in the licence for sale or other commercial purposes;
- to hatch, rear, breed, display or grow fish (other than bivalve shellfish for human consumption, abalone or eels) or fishing bait specified in the licence for sale or other commercial purposes; and
- to use commercial aquaculture equipment specified in the licence.
An Aquaculture (Crown Land - Bivalve Shellfish) Licence authorises the licence holder, on the Crown Land and in or on the protected waters covering that land specified in the licence:
- to use, form or create a habitat for rearing or growing bivalve shellfish specified in the licence for human consumption, for sale or other commercial purposes;
- tto rear or grow bivalve shellfish specified in the licence for human consumption, for sale or other commercial purposes; and
- tto use commercial aquaculture equipment specified in the licence.
Holders of an Aquaculture (Crown Land - Bivalve Shellfish) Licence are required to participate in the Victorian Shellfish Quality Assurance Program (VSQAP).
An Aquaculture (Crown Land - Abalone) Licence authorises the licence holder, on the Crown Land and in or on the protected waters covering that land specified in the licence:
- to use, form or create a habitat for hatching, rearing, breeding, displaying or rowing abalone (including a commercial quantity) specified in the licence for sale or other commercial purposes;
- to hatch, rear, breed, display or grow abalone (including a commercial quantity) specified in the licence for sale or other commercial purposes;
- to use commercial aquaculture equipment specified in the licence;
- to possess abalone (including a commercial quantity) which has been hatched, reared, bred or grown under the licence at the area specified in the licence;
- to process (other than to shuck) abalone (including a commercial quantity) which has been hatched, reared, bred, displayed or grown under the licence at the area specified in the licence; and
- to sell abalone (including a commercial quantity) which has been hatched, reared, bred, displayed or grown under the licence at the area specified in the licence.
In accordance with the Fisheries Act, aquaculture licences are subject to any conditions imposed by the Fisheries Act, any conditions that are set out in the Fisheries Regulations 1998 (the Fisheries Regulations) and any conditions that the Secretary, DPI thinks appropriate and that are expressed or referred to in the licence. Failure to comply with a condition of a fishery licence is an offence under the Fisheries Act.
Shellfish quality assurance
The VSQAP operates within Victoria monitoring aquaculture harvesting areas from which bivalve shellfish may be harvested for human consumption. The VSQAP is the Victorian implementation of the Australian Shellfish Quality Assurance Program (ASQAP), an internationally recognised program. Aquaculture fisheries reserves compliant with the VSQAP may be accredited for the harvest of product for export. Fisheries Victoria is presently responsible for administering the VSQAP. The monitoring component of the program has been outsourced.
Shellfish quality assurance has occurred in Victoria since 1987. Aquaculture (Crown Land ' Bivalve Shellfish) Licences entitle commercial production of bivalve shellfish for the purposes of human consumption and establishes a formula for calculating an industry VSQAP levy. The industry VSQAP levy represents one-third of the total costs of administering the VSQAP program as determined by the Secretary, DPI. The levy does not apply to farmers only producing bivalve spat for the purposes of ongrowing, or bait.
Shellfish harvesting for human consumption is regulated by harvest area closures using precautionary rainfall and phytoplankton triggers (Appendix 6). In addition, biotoxin events are managed under the Biotoxin Management Plan 2004.
Compliance
An aquaculture compliance strategy has been developed for the Port Phillip Region and includes the PCAFR. The strategy identifies compliance with licence conditions and lease clauses, including infrastructure type and location, labelling, and activity undertaken within the PCAFR, as a priority. Compliance with the VSQAP, and in particular harvesting closures, to protect human health is also a priority of the strategy.
Co-management
The co-management of fisheries and aquaculture within Victoria is a process involving four groups of entities. The first comprises the peak bodies: the Seafood Industry Victoria (SIV), VRFish (Victorian Recreational Fishing Peak Body), and the Victorian National Parks Association (VNPA).
The second group for marine aquaculture in Victoria comprises of existing aquaculture operators represented by bodies such as the Victorian Marine Farmers Incorporated and the Victorian Abalone Growers Association.
The next group comprises the Fisheries Co-Management Council (FCC) and its technical based committee.
The fourth group is the government agencies, including the DPI of which Fisheries Victoria is a Division.
The above co-management entities will ensure that the marine aquaculture industry is appropriately represented during consultation regarding decisions that may impact on the industry.
Preparation of the Pinnace Channel Aquaculture Fisheries Reserve Management Plan
Part three of the Fisheries Act provides the legislative framework for the preparation of management plans. The Fisheries Act also provides the means for the Secretary, DPI to implement the recommendations of a management plan. The Fisheries Regulations and licence conditions provide the statutory rules and licence entitlements and conditions governing commercial aquaculture.
The process for developing management plans is well defined and entails the following steps:
- identification of relevant issues and options for addressing those issues;
- reparation of a draft management plan addressing the issues identified and developing the options for dealing with the issues; and
- finalisation of the draft management plan following stakeholder submissions.
The PCAFR Management Plan was prepared by Fisheries Victoria, assisted by a steering committee comprising of representatives from key stakeholders including the peak bodies (VRFish and SIV) recognised under the Fisheries Act, the FCC, the DPI and the Department of Sustainability and Environment (DSE) (Appendix 7). Industry expertise was provided by the VAC (formerly the aquaculture peak body until 2004). The role of the steering committee was to advise the Executive Director, Fisheries Victoria, DPI with respect to the conformance of the Plan with the requirements of the Fisheries Act and the Ministerial guidelines, and to respond to community consultation on the draft Plan.
The issues that are presented in the Plan have been identified from other management plans in Victoria, other states and countries, consultation with industry and government agencies, and other documentation such as policies, plans, research reports and assessments (including an expert panel risk assessment; see below).
The issues addressed include the requirements of the Fisheries Act, Ministerial guidelines issued in respect of the fisheries reserves and emerging issues. In cases where a number of issues arise within a topic, these issues are presented under subheadings which identify the particular issues.
The scope of the Plan is:
- limited to the PCAFR and consideration of its immediate environs;
- consistent with the provisions of the Fisheries Act and Fisheries Regulations, the Victorian Government response to the recommendations of the ECC in the final report of their Marine Coastal and Estuarine Investigation (2000), and the Ministerial guidelines issued in respect of the Plan;
- consistent with other key legislation, including:
- Coastal Management Act (Victoria) 1995;
- Environment Protection Act (Victoria) 1970;
- Environment Protection and Biodiversity Conservation Act (Commonwealth) 1999;
- Flora and Fauna Guarantee Act (Victoria) 1988;
- Land Act (Victoria) 1958;
- Marine Act (Victoria) 1988;
- Native Title Act (Commonwealth) 1993; and
- consistent with other key Government policies, including:
- Guidelines for Assessing Translocations of Live Aquatic Organisms in Victoria 2003;
- National Aquaculture Action Agenda 2002;
- National Competition Policy 1995;
- Office of Regulatory Reform Aquaculture Task Force Report 1999;
- State Environment Protection Policy (Waters of Victoria) 2003 and the relevant schedules;
- Victoria's Biodiversity Strategy 1997;
- Victorian Aquaculture Strategy 1998;
- Victorian Coastal Strategy 2002;
- Victorian Government response to the ENRC Inquiry into Fisheries Management - First Report: Co-Management 2001;
- Victorian Government response to the ENRC Inquiry into Fisheries Management - Second Report 2002; and
- Victorian Government response to the ENRC Inquiry into Utilisation of Victorian Native Flora and Fauna 2000.
Objectives of the Plan
As previously stated, the purpose of the Plan is to ensure the management of the PCAFR is undertaken within an ESD framework, which incorporates principles of environmental sustainability, economic viability, social equity and governance. Accordingly the Plan addresses objectives under four key headings.
Ecological objectives
A key aspect of the Plan is to provide for the sustainable use of the natural resources within the PCAFR. To this end the Plan specifies ecological objectives, strategies, performance indicators, reference points and management triggers for the PCAFR. Additionally, the Plan specifies environmental survey, monitoring and reporting requirements to assess the effectiveness of management, in association with formal processes for deciding on appropriate actions in the event of adverse outcomes.
Economic objectives
The Plan aims to promote the development of an efficient, effective and economically viable aquaculture industry. In pursuit of this aim, the Plan provides for the maximum sustainable level of development, research and development, the appropriate allocation of water and security of occupancy rights.
Social objectives
An important goal of the Plan is the management of the PCAFR that provides for, as far as possible, social equity. To this end the Plan recognises the rights of other users of the marine environment. The Plan will provide for maximum benefit to the community and promote those benefits to the broader community.
Governance objectives
In respect of governance, the Plan aims to provide clear, transparent and cost-effective management of the PCAFR. In pursuit of this goal the Plan will be consistent with government legislation and policies on resource allocation, the issuing of aquaculture licences and Crown leases and recovery of attributed costs. The Plan will also address the regulation of licensed activities with the aim of maximising compliance. This will be achieved by developing a compliance framework including the development of a compliance strategy and through the quantification and monitoring of enforcement targets. Additionally, the Plan provides for the appropriate level of clear and timely reporting to the community in relation to the ecological and commercial status of the PCAFR.
Risk assessment
The key issues and risks associated with each objective of the Plan were identified through an expertise based risk assessment. This assessment followed the Australian/New Zealand Standard for Risk Management (AS/NZS 4360:1999).
Critical ecosystem components and current or potential threats
Aquaculture may impact on the marine environment, however the actual risks associated with marine aquaculture development are site specific depending on the species, location (characteristics and sensitivity), culture system and husbandry methods employed. Site specific risks have been assessed for the PCAFR and management measures are detailed in the Plan.
Bivalve shellfish will initially dominate aquaculture activity at the PCAFR, with the potential development of abalone cage culture. Bivalve shellfish are farmed using techniques reliant on natural productivity (no active feeding), resulting in a net removal of nutrients from the water column at harvest. Cage abalone aquaculture requires use of harvested macroalgae and or artificial feeds (active feeding) in addition to natural productivity. The ecosystem issues associated with bivalve shellfish and abalone cage culture are summarised in Appendix 6.
Finfish aquaculture will only be considered on a research and development basis. There will be no commercial culture of finfish within the life of the Plan.
Pinnace Channel Aquaculture Fisheries Reserve Management Plan
Duration of the Plan
The Plan will provide the basis for the management of the PCAFR for a period of three years. Prior to that time the Plan will be subject to review. Should there be a need for the Minister to amend the Plan prior to its review, notice of this intention will be published in the Victoria Government Gazette and there will be formal consultation with stakeholder groups.
Vision of the Plan
The vision of the Plan is:
'the development of ecologically sustainable, economically viable and socially equitable marine aquaculture at the PCAFR that contributes a significant commercial supply of high quality seafood.'
Management objectives and strategies
The objectives and strategies designed to implement the vision of the Plan are as follows:
Ecological
Objectives:
- to ensure the ecological health of areas adjacent to the PCAFR is not jeopardised as a result of aquaculture activity within the PCAFR;
- to limit ecological impacts within the PCAFR as a result of aquaculture activity to local, acceptable and reversible change; and
- to provide management responsiveness to changes in the ecological health within the PCAFR and adjacent areas.
Strategies:
- identify the biological and ecological factors relevant to the management of the PCAFR;
- identify critical components of the environment, current or potential threats to those components, and existing or proposed preventative measures;
- specify permissible aquaculture activities consistent with the principles of ESD-based aquaculture;
- specify relevant performance indicators, reference points, management triggers and monitoring requirements;
- specify management actions to be undertaken in response to management triggers being breached; and
- monitor areas and functions of licence holders and instigate appropriate management actions.
Economic
Objectives:
- to facilitate economically efficient, effective and sustainable commercial aquaculture production within the PCAFR;
- to provide for commercial aquaculture opportunities within the PCAFR to be utilised at the maximum sustainable level;
- to encourage aquaculture investment within the PCAFR by contributing to a positive investment climate and maintaining market access; and
- to enhance commercial production by facilitating appropriate research and development.
Strategies:
- identify the economic factors relevant to the management of the PCAFR;
- define a process to determine the area to be allocated, size of Crown lease sites and infrastructure restrictions consistent with best practice marine farming and the carrying capacity of the PCAFR;
- provide for consent to use and develop Crown Land, and occupational authorisation and security of tenure for aquaculture investors via Crown lease provisions;
- identify relevant research and development needs, and facilitate and promote research and development collaboration in the PCAFR;
- develop and maintain the VSQAP and other quality assurance programs relevant to the PCAFR; and
- specify the minimum rate of infrastructure development on aquaculture sites within the PCAFR.
Social
Objectives:
- to recognise the rights of other users of the marine environment consistent with the Victorian Government response to the ECC recommendations for marine aquaculture;
- to utilise marine environmental monitoring information for the benefit of the wider community; and
- to facilitate maximum benefit to the community where there is private commercial use of a publicly owned resource.
Strategies:
- identify the social factors relevant to the management of the PCAFR;
- specify navigation marking requirements;
- specify guidelines regulating or restricting non-aquaculture activity in the PCAFR;
- specify and make available appropriate environmental and production data for broader public use; and
- increase awareness of the PCAFR aquaculture and its associated regional economic development and employment to the wider community.
Governance
Objectives:
- to provide for open and transparent allocation of resources;
- to provide management which is cost effective and transparent, including open and transparent reporting of ESD outcomes;
- to provide for the recovery of the attributable costs of management, including research and development and compliance, in line with Government policy; and
- to ensure licensed activities are appropriately regulated according to legislation.
Strategies:
- recognise government policies relating to cost effective and transparent management, public reporting of ESD outcomes, and recovery of attributed costs;
- recognise criteria to be used in respect of the issue of Crown leases, aquaculture licences and general permits;
- recognise co-management entities and associated functions, and stakeholder satisfaction; and
- establish compliance criteria and recognise compliance management strategies.
Performance indicators, reference points and management triggers
Performance indicators are quantities to be measured in order to track the status of the PCAFR relevant to the stated objectives.
Reference points represent the status management wishes to achieve. When the status is unacceptable, management triggers indicate the requirement for an appropriate remedial action.
Performance indicators, reference points and management triggers for the Plan are shown in Table 3 and have been assigned to each of the PCAFR objectives, where appropriate. Current information does not allow for the precise definition of all performance indicators and reference points and further research is required to provide this information.
It should be noted that the action resulting from non-compliance of a management trigger is described under the relevant section in the Plan. However, in those cases, where there is not a clear action described in the Plan, the action resulting from non-compliance of a management trigger will be a review of the particular issue.
The Plan makes recommendations on the responsibilities of Crown lease and aquaculture licence holders. These responsibilities are summarised in Appendix 8.

Table 3: Performance indicators, reference points and management triggers for the Pinnace Channel Aquaculture Fisheries Reserve Management Plan
Species
The declaration of the PCAFR provides the opportunity for increased production of presently cultured species, as well as the opportunity for the commercial and experimental culture of new species.
Consideration of the species permitted for culture in the PCAFR must be consistent with Government legislation and policies including:
- the Guidelines for Assessing Translocations of Live Aquatic Organisms in Victoria 2003;
- the Victorian Government response to the final report of the Environment Conservation Council's Marine Coastal and Estuarine Investigation (2000);
- the State Environment Protection Policy (Waters of Victoria) 2003 and associated Port Phillip Bay Environmental Management Plan 2002; and
- the relevant fishery management plans, including the Victorian Abalone Fishery Management Plan 2002.
Finfish
The culture of finfish in the PCAFR will not be permitted in the life of the Plan. At present adequate information on the environmental impacts and associated management of commercial finfish aquaculture in PPB is not available.
To address the information gaps, appropriate research and development on finfish culture in the PCAFR will only be conducted to provide relevant, creditable information on the ecological sustainability of such activity. Any finfish research will be designed and evaluated in conjunction with the DSE and the Environment Protection Authority (EPA). All research and development will be subject to conditions prescribed in the 'Research and development' section of the Plan.
Shellfish
Culture of bivalve shellfish species, including blue mussels, scallops, flat oysters, and cage culture of abalone can be adequately managed within an ESD-based framework in the PCAFR
Abalone ranching3 will not be permitted in the life of the Plan. At present, adequate information on the environmental impacts and associated management is not available for ranching of abalone.
Other species
Culture of other species may be permitted provided they meet the requirements of relevant legislation and policy, and can be adequately managed within an ESD-based framework.
Authorisations to conduct aquaculture activity
Three authorisations will be required to conduct aquaculture in the PCAFR:
1. Crown leases
A Crown lease for marine aquaculture will be issued under the Land Act to a leaseholder and will provide exclusive occupancy right over a site for aquaculture purposes.
2. Aquaculture licences
An aquaculture licence will be issued under the Fisheries Act to a licence holder and will authorise an operator to conduct aquaculture activity on a specified area.
3. Coastal consent
Consent under the Coastal Management Act will authorise the use and development of coastal Crown Land.
Crown leases for marine aquaculture
Entitlements of a Crown lease for marine aquaculture will be consistent with the Victorian Aquaculture fisheries reserves - leasing and licensing policy.
It should be noted the Crown lease will provide occupancy rights for the purpose of conducting aquaculture activity, while the aquaculture activity will be authorised by an aquaculture licence.
Crown leases within the PCAFR will be allocated consistent with the Victorian Aquaculture fisheries reserves - leasing and licensing policy. Accordingly the Plan concerns management of those sites and associated aquaculture activity once allocated, rather than the specifics of the allocation mechanism.
The transfer, amalgamation, subdivision and subleasing of Crown leases within the PCAFR will be consistent with the Victorian Aquaculture fisheries reserves - leasing and licensing policy.
Aquaculture licence - classification, renewal, transfer and variation
Aquaculture licences issued under the Fisheries Act will provide authority to the licence holder to conduct aquaculture activity within the PCAFR.
An aquaculture licence specifying an area within the PCAFR will only be issued, renewed or transferred if consistent with the Victorian Aquaculture fisheries reserves - leasing and licensing policy. Cost recovery for management of the PCAFR will occur through the implementation of levies on aquaculture licences. Existing legislation provides that levies may only be prescribed for a class of fishery licence. In order to comply with this legislation and facilitate cost recovery, Fisheries Victoria will develop classes of aquaculture licence that may authorise aquaculture activity within the PCAFR. Of these, one will relate to the authority to harvest bivalve shellfish for human consumption and others will relate to the authority to culture aquaculture product for purposes other than the harvest of bivalve shellfish for human consumption.
General Permits
In addition, general permits will be issued as required to conduct aquaculture activity for research and development purposes. Research and development under the provisions of a general permit may only be conducted within a defined research and development site within the PCAFR (refer to Research and development). General permits will not be allocated for other sites within the PCAFR.
Environmental management
The Government supports marine aquaculture initiatives subject to appropriate environmental management.
In their response to the ECC recommendations for marine aquaculture (2000), the Victorian Government indicated that:
'The purpose of a Management Plan is to specify policies and strategies to ensure the ecologically sustainable development of aquaculture zones. Accordingly the Management Plan will specify commitments to monitoring ….'
The Government also endorsed the ECC recommendation that:
'NRE4 expand existing and introduce new research and monitoring programs for existing and new aquaculture operations to include the following:
- assessment of changes in benthic species composition and abundance beneath aquaculture farms;
- monitoring for introduced species, pathogens, diseases, nutrient enrichment (particularly when supplementary feeding is used) and other potential ecosystem effects on the surrounding environment;
- an assessment of recovery times following cessation of aquaculture activities in an area;
- participation by the proponent in, and contribution to, the cost of these programs; and
- publicly available reports' (recommendation 43).
The Government indicated that:
'Such detail will be outlined in the Management Plans for aquaculture zones, which will be released for public comment. The Management Plan will also give consideration to the indicators mentioned above, amongst others, and specify the frequency of public reporting'.
Environmental management framework for the PCAFR
One of the key management actions identified for the PCAFR is the development of an appropriately designed, comprehensive environmental management framework for the PCAFR. This framework will be based on three key components:
- a characterisation survey;
- a baseline survey; and
- ongoing monitoring.
Fisheries Victoria has reviewed the methods for environmental surveying and monitoring of marine aquaculture in Victorian waters (Gavine and McKinnon 2002) (see Table 4 for summary), which provides the technical basis for implementation of the environmental management framework within the PCAFR. This framework will provide information to enable management decision making, ensuring that the impact of aquaculture will be maintained at a level that is acceptable, local and reversible by natural processes.

Table 4: Variables and methods for environmental surveys and monitoring (Source: modified from Gavine and McKinnon, 2002).
1. Characterisation survey
A characterisation survey is a broad, one-off assessment of the habitat, physico-chemical and biological attributes of an aquaculture fisheries reserve. To identify the key environmental attributes of the PCAFR and relevant reference sites for future monitoring, Fisheries Victoria has undertaken a characterisation survey of the PCAFR (Barry and Bailey 2001; Coleman et al. 2001)5. The results of this survey are summarised in Appendix 5. Prior to the review of the Plan, Fisheries Victoria will undertake environmental assessment of the appropriate reference sites to monitor impacts within, and external to, the PCAFR.
2. Baseline survey
A one-off baseline survey is to be undertaken as soon as practicable after the Crown lease has been issued and prior to commencing aquaculture activity. A baseline survey is an initial assessment of the sediment and seabed (see Table 4) specific to the Crown lease site. This survey will include predetermined compliance point(s)6 outside the Crown lease site (reference sites) for the purpose of future ongoing monitoring by the aquaculture licence holder. It will be the responsibility of the Crown lease holder to undertake and fund the baseline survey for each Crown lease site.
The requirements of the baseline surveys will be specified by the Secretary, DPI and prescribed as lease clauses. A written report on all baseline surveys is to be provided to Fisheries Victoria by the date specified by the Secretary, DPI. The report will provide a summary of data collected, methods employed, analysis of the data, and recommendations and conclusions.
All original data, video footage and samples should be retained by the Crown lease holder for auditing purposes for a period of time as specified by the Secretary, DPI.
3. Ongoing monitoring
Ongoing monitoring is to be undertaken subsequent to the baseline surveys on an annual basis, or at intervals specified by the Secretary, DPI. Monitoring refers to ongoing assessment of the sediment and seabed (see Table 4) of the aquaculture licence sites. Ongoing monitoring will include assessment of relevant reference sites and provide sufficient information on the performance indicators to determine whether reference points are being achieved. It will be the responsibility of the licence holder to undertake and fund the ongoing monitoring.
The ongoing monitoring will be specified by the Secretary, DPI and prescribed as licence conditions. A written report on all ongoing monitoring is to be provided to Fisheries Victoria by the date specified by the Secretary, DPI. The report will provide a summary of data collected, methods employed, analysis of the data, and recommendations and conclusions.
All original data, video footage and samples should be retained by the licence holder for auditing purposes for a period of time specified by the Secretary, DPI.
Environmental survey and monitoring guidelines
Guidelines prepared by Fisheries Victoria in consultation with the relevant agencies will prescribe detailed methods and standards for undertaking baseline surveys and ongoing monitoring. These guidelines will include a description of the following key parameters: physico-chemical analysis of the sediment (particle/sediment grain size analysis, oxidation reduction potential, total organic carbon, carbon to nitrogen ratios and natural stable isotope analysis), biological analysis of the sediment, seabed characteristics and habitat profile (habitat mapping, underwater video survey), and water column. All baseline surveys and ongoing monitoring are to be conducted using the prescribed methods and in accordance with the prescribed standards unless otherwise authorised. The guidelines will also provide for reporting and auditing of all survey and monitoring results.
Data management
Fisheries Victoria will develop a data management system with geographical information system overlay capable of storing, analysing and reporting on all survey and monitoring data.
Environmental standards
Environmental standards for aquaculture activity within the PCAFR are impacts that are acceptable, local and reversible by natural processes. In the event the environmental standards are not met, appropriate remediation action will be undertaken.
Environmental performance indicators, management triggers and associated remediation actions for marine aquaculture activities are described in Table 5. Remediation of the site will be at the direction of the Secretary, DPI. The undertaking of remedial actions will be the responsibility of the aquaculture licence holder.
Fisheries Victoria will be responsible for evaluating whether performance indicators are meeting reference points, or if management triggers have been activated, and for determining the appropriate management responses.
Continual review of environmental monitoring information, combined with the ability to vary licence conditions relating to environmental monitoring, provides for adaptive management to reflect effective and efficient management response to changing conditions.
Public reporting
Public reporting on environmental monitoring undertaken within the PCAFR is a primary component of public accountability for the management of the PCAFR. Fisheries Victoria will publish all characterisation survey information. All baseline survey and ongoing monitoring information will be available to the public. Fisheries Victoria will provide annual summaries of this information.
Disease
The Organisation Internationales Epizootiques (OIE) is the international organisation responsible for the International Aquatic Animal Health Code (OIE 2004). Australia is a member country of the OIE. Australia's responsibilities under the OIE for aquatic animal diseases are reflected in the Aquaplan Control Centre Manual (AFFA, 2001), overseen by the Commonwealth Committee for Animal Emergency Diseases. Victoria's national aquatic animal disease reporting requirements are reflected in Victoria's Arrangements for the Management of Aquatic Animal Disease Emergencies 2003. Further it is a requirement under the Fisheries Act and the Livestock Disease Control Act 1984 that prescribed notifiable diseases are reported to the Secretary, DPI and the Chief Veterinary Officer, DPI respectively.
The degree of disease risk for marine aquaculture at the PCAFR will vary with the choice of culture species and system, the standard of management, and the prevailing environmental conditions in and around the aquaculture areas. In relation to the farm management component, the prescribed procedures and protocols adopted by industry to avoid, mitigate and or treat disease incidents will be critical to ensuring disease risks are (economically and environmentally) manageable.
All aquaculture licence holders within the PCAFR must comply with the appropriate disease reporting requirements and management response initiatives.
The risk of disease transmission into and out of the PCAFR will be managed under the Guidelines for Assessing Translocations of Live Aquatic Organisms in Victoria 2003.
During the life of the Plan, Fisheries Victoria, in consultation with the Chief Veterinary Officer, DPI and industry will investigate whether an active disease surveillance program for the PCAFR is warranted.
Translocation
Translocation of live aquatic organisms poses an ecological risk through the potential transmission of diseases, potential impacts on biodiversity from changes in genetic integrity, and the establishment of feral and or exotic populations. The Victorian Government has developed Guidelines for Assessing Translocations of Live Aquatic Organisms in Victoria 2003 using the National Policy for the Translocation of Live Aquatic Organisms 1999
Translocations will be conducted in accordance with the Guidelines for Assessing Translocations of Live Aquatic Organisms in Victoria 2003 and any associated protocols approved by the Secretary, DPI. Interim translocation protocols include The Revised Victorian Mussel Translocation Protocol for the Movement of Mussel Ropes and Equipment between Port Phillip Bay and Western Port 2004 are to be used when appropriate. Fisheries Victoria will develop further translocation protocols as appropriate.

Quality assurance programs
Victorian Shellfish Quality Assurance Program
The VSQAP is the Victorian implementation of the ASQAP, an internationally recognised program. The VSQAP is a quality assurance program protecting human health through the active monitoring of shellfish harvesting areas (fisheries reserves). Aquaculture fisheries reserves compliant with the ASQAP will be accredited for the harvest of product for export.
The VSQAP will be extended to include the PCAFR. Proponents harvesting bivalve shellfish for human consumption must hold a relevant Aquaculture (Crown Land - Bivalve Shellfish) licence and contribute to the costs of the VSQAP. All bivalve shellfish harvested for human consumption must be compliant with the VSQAP.
The PCAFR is located distant to most potential sources of pollution that would restrict harvest for human consumption and or export clearance for product harvested from the reserve, as defined by the ASQAP. Combined with potential for large quantities of bivalve shell stock to be produced within the reserve, the PCAFR is a prime location to grow and harvest bivalve shellfish for export.
It is intended that export accreditation for the shell stock harvested from the PCAFR will be achieved via the VSQAP process as soon as possible after the allocation of Crown leases within the reserve.
Food safety plans
The Seafood Safety Act 2003 (the Seafood Safety Act) requires that all aquaculture licence holders producing product for human consumption hold a licence issued under that Act (administered by PrimeSafe). The Minister responsible for the Seafood Safety Act may declare that a class of seafood licence is to have a food safety program. Holders of those licences will have to prepare and implement food safety plans that specify the Hazard Analysis Critical Control Points through supply-chain food safety requirements.
Limitations on active feeding of artificial feeds7
Bivalve shellfish are farmed using techniques reliant on natural productivity. Cage abalone aquaculture requires active feeding with natural macroalgae and or artificial feeds. Commercial culture of finfish will not be permitted in the PCAFR for the life of the Plan.
Schedule F6 (Waters of Port Phillip Bay) of the State Environment Protection Policy (Waters of Victoria) 2003 (SEPP) requires a 1000 tonne net reduction in the annual net nitrogen load to PPB by 2006. The Port Phillip Bay Environmental Management Plan 2003 (PPBEMP) has been prepared to help achieve the objectives of the SEPP. This plan includes strategies to achieve the net nitrogen reduction outlined by the SEPP. The PCAFR will be developed in accordance with the SEPP and the requirements of the associated PPBEMP. Any aquaculture proposals that require active feeding of artificial feeds will therefore be required to comply with the SEPP, including the requirement for a net reduction in nutrient loads, and be consistent with the PPBEMP.
Commercial aquaculture activity requiring use of artificial feeds in the PCAFR will only be considered if it can be demonstrated that such operations can meet the requirements of the SEPP, and are consistent with the PPBEMP.
Research and development activities in relation to the use of artificial feeds in the PCAFR will be permitted on the basis that it is designed to provide relevant, scientifically defensible information on the ecological sustainability of such activity. All research and development will be subject to the conditions prescribed in the 'Research and development' section of the Plan. Within this context, the potential application of nutrient offset mechanisms8 will be investigated.
Production reporting
A condition on all aquaculture licences is that the licence holder must complete an aquaculture production return. These data are provided to meet Fisheries Victoria's state, national and international reporting requirements. Production data are made available to the public by Fisheries Victoria in the Commercial Fish Production Bulletin for each financial year.
The public will be informed on the production from the PCAFR. All production information for the PCAFR may be reported to the public, including the species cultured, the tonnage and value of product, and the employment created. The annual Commercial Fish Production Bulletin provides a mechanism for providing these data to the public. All information provided on production within the PCAFR will be in a form that protects commercial confidentiality of individual licence holders, providing this requirement does not prevent production reporting for the PCAFR.
Fisheries Victoria, following consultation with relevant industry representatives and existing licence holders, will determine the reporting requirements for financial performance indicators.
General public access
When considering general public access to the PCAFR there are two types of areas to be considered:
- sites specified on Crown leases and or aquaculture licences; and
- areas within the PCAFR that have not been specified on Crown leases and or aquaculture licences.
The Victorian Government response to the ECC (2000) recommendations provided that other users could access the aquaculture fisheries reserve but not the Crown lease sites.
General public access will only be permitted to areas of the PCAFR that are not leased or licensed. The external boundaries of the leased sites will be marked in accordance with the provisions of the Marine Act 1988 (the Marine Act) to provide the appropriate indication to other users of restricted access areas. A communication strategy will be developed in consultation with relevant industry representatives and VRFish to inform the public and industry of the entitlements of other users. The compliance strategy developed relating to the PCAFR will address compliance with access restrictions.
To ensure the profitability of aquaculture operations within the PCAFR is not jeopardised by the activities of other users, the following management arrangements are recommended:
- Fisheries Victoria, following consultation with stakeholders, will implement and enforce an appropriate speed limit for boating within the PCAFR;
- the cleaning of fish will not be permitted in the PCAFR;
- the use of berley will not be permitted within the PCAFR and should not be permitted within 500m of the PCAFR;
- recreational fishing, diving and associated charter boats will be permitted to the edge of the Crown lease sites, but casting or drifting lines into and diving in the leased sites will not be permitted;
- commercial fishing will not be permitted within the PCAFR; and
- the compliance strategy relating to the PCAFR will recognise that the disposal of human sewage and other litter in PPB is illegal under the Environment Protection Act.
Survey and navigation marking
Providing Crown leases within the PCAFR is an alienation of Crown land. It is therefore appropriate to ensure that all lease sites are accurately surveyed and marked to the appropriate standard.
Surveying
Surveying of aquaculture sites must be of a standard considered appropriate for issuing of Crown leases. Standards of surveying for the granting of registered Crown leases are the responsibility of the Surveyor General Victoria and Land Registry, Land Victoria and DSE. Independent Licensed Surveyors will conduct the surveying. The DPI will provide guidelines for surveying of marine waters for the purposes of Crown leasing in conjunction with the Surveyor General Victoria. Crown lease sites within the PCAFR are to be surveyed by the Crown lease holder at their expense, prior to placing any commercial aquaculture equipment on the lease site.
To ensure the Crown lease sites are accurately marked, they will be regularly inspected by Fisheries Victoria and surveys will be requested if appropriate. A current aquaculture licence condition is:
'Upon the request of the Secretary, the aquaculture licence holder must provide a plan of survey of the aquaculture sites on this licence which '
- is undertaken by a qualified surveyor or other person approved by the Secretary.
- is suitable for registering on a Crown lease.
- indicates the location of a licence holder's commercial aquaculture equipment in relation to boundaries of the aquaculture sites specified on this licence.
- is completed and forwarded to the Secretary within 120 days of such a request being made.'
In regard to the accurate marking of site boundaries this licence condition will be adapted as a standard Crown lease clause.
The maintenance of aquaculture equipment within the Crown lease boundaries is the responsibility of the aquaculture licence holder. Local currents, wind and wave action can affect the location and alignment of aquaculture infrastructure. Fisheries Victoria will undertake regular monitoring and enforcement of the location of commercial aquaculture equipment. Any survey in relation to the location of aquaculture equipment on an aquaculture Crown lease requested by the Secretary, DPI for compliance purposes will be undertaken at the expense of the aquaculture licence holder. In addition, any cost for relocation of equipment will be borne by the aquaculture licence holder.
Navigation marking
Existing aquaculture within PPB is generally conducted in large aquaculture zones within which aquaculture licence holders are allocated individual 3 ha sites. The boundaries of the larger existing aquaculture zones at Clifton Springs and Grassy Point are delineated by navigation markers consistent with the requirements of the appropriate authorities under the Marine Act. These navigation markers were deployed and are maintained by Fisheries Victoria. Currently aquaculture licence holders are required to mark each corner of each licensed site with a buoy bearing the licence holder's number. Deployment and maintenance of these buoys are the responsibility of the licence holders.
The external boundaries of the PCAFR will be marked by Fisheries Victoria in accordance with the requirements of the appropriate authorities under the Marine Act. To ensure all navigation marks are in the correct working order Fisheries Victoria will prepare and implement a program for the regular inspection and maintenance of all navigation marks for the external boundaries of the PCAFR. Fisheries Victoria will implement a system to recover all cost associated with the inspection and maintenance of navigation marks for the external boundaries of the PCAFR from the aquaculture licence holders. The recovery of these costs should be levied on licence holders receiving benefits pro rata on the basis of area licensed.
Crown lease holders will be required to mark the external boundaries of the lease site with boundary marks in accordance with the requirements of the appropriate authorities under the Marine Act and regularly inspect and maintain boundary infrastructure at their own expense. All aquaculture sites will be surveyed and marked appropriately before commercial aquaculture equipment is deployed.
Fisheries Victoria will communicate information regarding the type and location of navigation markers for the PCAFR to other users.
Infrastructure requirements
The ECC (2000) recommended that management plans prepared for marine aquaculture fisheries reserves include 'design, construction, maintenance and visual impact of structures' (recommendation 41). It is appropriate that the Plan considers conventions to reduce the visual impacts associated with aquaculture infrastructure within the PCAFR.
The visual impacts discussed here are those associated with commercial aquaculture equipment only, and not navigation marking infrastructure (as previously described). At present the marine aquaculture industry within PPB uses a variety of visible infrastructure (size, shape and colour) on licensed sites to support aquaculture equipment. In the PCAFR the use of low profile, dark coloured buoys will reduce the visual impact of this infrastructure. All buoys (non-navigation marks) and other floating commercial aquaculture equipment within the PCAFR will be grey to black in colour or be any other colour that is specified by the Secretary, DPI. Commercial aquaculture equipment and support infrastructure in the PCAFR should be distinctive to the boundary marks of Crown lease areas and the PCAFR.
Aquaculture infrastructure may detach creating a safety risk and litter the adjacent foreshore. The risk of detachment of buoys will be reduced by prescribing minimum standards for attachment of buoys to longlines in licence conditions. Maintenance of these standards will be addressed as part of the compliance strategy relating to the PCAFR.
All floats and buoys associated with commercial aquaculture equipment and support infrastructure deployed within the PCAFR must be marked to allow the identification of the relevant aquaculture licence holder.
The presence of redundant and or dilapidated commercial aquaculture equipment or associated infrastructure also affects visual amenity, environmental values and creates a safety hazard. The PCAFR must be kept in a neat and tidy manner and an aquaculture licence condition will be developed requiring all redundant or dilapidated commercial aquaculture equipment to be removed from the licence site upon request of the Secretary, DPI.
The deployment of commercial aquaculture equipment and support infrastructure outside of the lease site creates a safety hazard to other users of the PCAFR. All commercial aquaculture equipment, including all anchors and mooring lines, and other support infrastructure located within the PCAFR must be located within Crown lease sites.
The mooring of barges, boats and other structures within the PCAFR for periods longer than five consecutive days will require written approval from Fisheries Victoria, DPI.
Noise and lighting
While technological advancements have improved the industry's productivity, eliance on motorised equipment may increase the incidence of noise. In addition, night time activity may occur. At present, night time aquaculture activity is predominantly associated with harvest events to meet market deadlines and or to beat advancing weather. The noise and light resulting from these activities has the potential to negatively impact other marine users and the marine environment. Therefore, growers must be sensitive to this issue and take the appropriate steps to minimise any potential impacts.
International practice requires marine farmers to conduct all activities in a manner that is respectful of other marine users and the environment. This includes:
- restricting noise and light to harvesting activities, normal operational practices and or maintenance of safety;
- ensuring all non-navigation lighting must be aimed, and of a brightness, so as not to cause unnecessary adverse affects on other users and the marine environment, and where possible, should be shielded from all but essential directions;
- making every reasonable effort to minimise noise during regular farming activities, including ensuring well-maintained sound suppression devices (for example mufflers, barriers and baffles) are used while operating equipment; and
- making every reasonable effort to minimise light during night time operations.
It is a requirement of the Plan that the above issues be considered in codes of practice developed by industry for application within the PCAFR. The role of environmental management plans in control of noise and lighting should be considered during the development of industry codes of practice within the life of the Plan.
Waste management
Waste management is an important environmental issue within the PCAFR. As the maintenance of water quality is of paramount importance to aquaculture ventures, poor waste management will also impact adversely on aquaculture operations. Potential wastes at the PCAFR include harvesting, cleaning, processing and mortality wastes; chemical and industrial waste; and sewage.
Under the Environment Protection Act discharges to the marine environment must be managed so that they do not adversely affect the receiving environment. The SEPP establishes ambient water quality objectives and waste water discharge limits (based on the Australian Guidelines for Water Quality Monitoring and Reporting - Summary 2000) to protect these waters.
Further, the Health Act 1958 (the Health Act) makes provisions for the prevention of conditions or activities that may be offensive or dangerous to the public, and the Food Act 1984 (the Food Act) requires the maintenance of prescribed food standards.
Harvesting, cleaning, processing and mortality wastes
Solid wastes from harvesting or cleaning (for example removal of biofouling) of all shell stock (including bait and spat) and from cleaning commercial aquaculture equipment (including ropes and buoys) must be disposed of in an appropriate manner. All declumping and cleaning of shell stock for human consumption must be in accordance with the requirements of the ASQAP. All declumping and cleaning of shell stock and commercial aquaculture equipment must occur either:
- within the licensed site; or
- at a designated area that is appropriately monitored in compliance with the ASQAP and or other environmental monitoring requirements; or
- onshore in appropriately designated areas subject to the provisions of local government, local water authorities and the EPA.
Solid wastes from post-harvest processing of shellfish (for example shucking) must be disposed subject to the provision of local government, local water authorities and the EPA.
In accordance with the Fisheries Act, abalone may only be processed at specified premises by the holder of a Fish Receivers (Abalone) Licence. As a result processing of abalone is not permitted within the PCAFR.
Chemical and industrial wastes
Chemical use for marine bivalve aquaculture is limited to minor use of antifoulants. Any use of chemicals must be in accordance with the provision of all relevant statutes including the Environmental Protection Act and associated subordinate legislation. All chemicals used must be approved for use in the marine environment and should only be used according to manufacturer's specifications.
Other chemical and industrial wastes in the PCAFR may include cleaning products and petroleum by-products such as diesel oil, motor oil and petrol. It is a requirement that the risk of impacts from these chemicals and industrial wastes will be dealt with by industry in accordance with relevant codes of practice and legislation. The role of environmental management plans in control of chemical and industrial wastes should be considered during the development of industry code of practice within the life of the Plan.
Sewage
Sewage contains a range of pathogenic microorganisms (including bacteria, viruses and protozoa) that pose a potential risk to the health of humans. Bivalve shellfish are particularly susceptible to effluent contamination. As a result the discharge of sewage into the marine environment in and adjacent to the PCAFR would pose significant human health risks through the potential contamination of aquaculture product.
The disposal of human sewage at sea is illegal under the Environment Protection Act and the associated SEPPs.
Lease dimensions, orientation and stocking rate
Determination of the total area of the PCAFR allocated to filter feeding shellfish culture and the maximum culture substrate per site allocated is based primarily on the carrying capacity of the PCAFR. Carrying capacity for commercial exploitation is defined as the quantity of standing stock (stocking rate) at which the annual production of a marketable crop is maximised. At a local scale, aquaculture stocking rates depend on constraints including substrate and oxygen availability, and food supply. For bivalves, the dominant factor determining the stocking rate is primary production (food supply). The stocking rate for bivalve shellfish is outlined below.
The maximum stocking rate at the Crown lease and PCAFR levels, for species other than bivalve shellfish species may be specified prior to granting Crown leases within the PCAFR for each species on a case by case basis if required.
Size, orientation and location of lease sites
Restriction of total production by area allocated and growing substrate controls allows the minimum economically viable lease size to be determined based upon standard production methods and return on investment. It is also noted in this context that return on investment is affected by economies of scale. For the purposes of this exercise a minimum scale of operation producing an acceptable rate of return and affording longterm viability will be applied. Fisheries Victoria, in consultation with industry, will determine the minimum lease size within the PCAFR, consistent with these parameters.
Location and orientation of Crown leases within the PCAFR will reflect separation distances to maintain adequate water flow, buffer zones9 around the periphery of the PCAFR, the direction of currents and access to lease sites. Fisheries Victoria, in consultation with industry, will determine the location and orientation of lease sites within the PCAFR.
Areas of the PCAFR other than those allocated for bivalve shellfish aquaculture or set aside for access/separation/ buffer zones may be used for the culture of other species that are actively fed and therefore not directly reliant on primary productivity (for example abalone). This use will be subject to approval of the Secretary, DPI and development of the appropriate input controls for these uses on a case by case basis.
Management controls for shellfish
In the absence of scientific data on the carrying capacity for the PCAFR it is appropriate that the precautionary principal is applied to carrying capacity controls. For the purposes of the Plan, relatively simple and efficient input controls will be used to determine the maximum stocking rates for the PCAFR. These controls are:
- total area allocated for bivalve shellfish aquaculture; and
- input controls related to length of longline.
At present, approximately 30% of the total area of existing aquaculture zones within PPB is allocated for bivalve shellfish aquaculture. The maximum total area for bivalve shellfish aquaculture within the PCAFR will be 50%.
Ongrowing substrate for bivalve shellfish aquaculture may be controlled by prescribing maximum length of longline backbone10 per ha of lease area. A maximum of 0.5 km of longline backbone will be permitted per ha in the PCAFR. This maximum will be prescribed as an aquaculture licence condition.
Rates of development
Implementation of the PCAFR alienates a community resource for the exclusive use of the aquaculture industry. The Victorian community has an expectation that the resource will be used by the aquaculture industry in a manner that maximises the return to the community. Return to the community is achieved in part by aquaculture development within the PCAFR, output of commercially valuable aquaculture product, the creation of regional employment opportunities, and the provision of ancillary support services to the aquaculture industry.
The specification of a minimum rate of development as a regulatory management tool is a mechanism used to ensure that the community will benefit from regional development, wealth creation and employment opportunities associated with a sustainable aquaculture industry. In addition, specified minimum rates of development make inappropriate investment speculation less likely and will encourage positive, legitimate and active development within the PCAFR.
Fisheries Victoria will ensure that minimum rate of development provisions are developed for aquaculture licences and Crown leases.
(a) Aquaculture licences
Aquaculture licence conditions prescribing minimum rates of development will be prepared for all aquaculture licences within the PCAFR. The development rates will be customised by Fisheries Victoria in consultation with the relevant stakeholders on a case by case basis and with reference to their development plan. Fisheries Victoria will ensure that provisions exist under the Fisheries Act to not renew licences when specified minimum development rates have not been met, subject to a 'show cause' provision. Where compelling reasons are offered in support of the renewal of a licence when minimum development rates have not been met, the licence may be renewed.
(b) Crown leases
Crown lease clauses will be developed to ensure that a Crown lease holder maintains a minimum rate of development on the Crown lease site. The Crown lease will stipulate a period of time within which minimum rates of development must first be met, and a maximum total number of years in which development may be below the specified level.
Ownership of stock on the seafloor
There are two potential sources of stock on the sea floor within marine aquaculture Crown leases:
- stock that has originated from the aquaculture operation and has fallen to the seafloor. This stock may be attached to aquaculture infrastructure that has become detached, for example a mussel dropper, or may be the result of spat/stock detached from aquaculture infrastructure. This stock would be the same as the species authorised for culture.
- stock that has settled or migrated to the seafloor by natural processes without interference from the aquaculture operation. This stock may include species listed on the aquaculture licence and also other species. This stock on the seafloor may be considered as 'wild' stock.
Any stock on the seafloor within the aquaculture licence site that directly results from the aquaculture activities, or is the same species as that authorised for cultured, may be retrieved by the aquaculture licence holder provided that it meets any appropriate health safety standards (for example the VSQAP) and licence conditions.
Stocking of the seafloor for commercial harvest will not be permitted within the PCAFR within the life of this Plan.
Any stock that is not a species listed on the aquaculture licence will not be accessible to the licence holder.
Research and development
Research and development is a tool to provide information to address risk and uncertainty, and as such facilitates the overall risk management and adaptive management approach of the Plan.
The broad, strategic drivers for determining the research and development priorities for the PCAFR include:
- the Victorian Government Response to the Final Report of the ECC Marine, Coastal and Estuarine Investigation (2000);
- relevant recommendations of the Federal Government's National Aquaculture Action Agenda 2002;
- all relevant research and development plans, including the Fisheries Co-Management Council Research Strategy, Research Needs and Priorities for Fisheries in Victoria 2001/02 - 2005/06 (FCC 2001); and
- needs of Crown lease holders and aquaculture licence holders within the PCAFR.
A research and development site will be allocated within the PCAFR. All such research and development will address agreed priorities, be coordinated, be collaborative (where appropriate), and at the discretion of the Secretary, DPI. Research and development in this site will be pursuant to section 140 of the Fisheries Act that is research carried out by the Secretary.
Reporting requirements and intellectual property ownership and management for research and development activities will be specified in research agreements as deemed appropriate by the Secretary, DPI.
A research and development action plan for offshore marine aquaculture, which will include the PCAFR, will be developed, reviewed and updated annually. The research and development plan will be reviewed and updated annually.
No general permits for research and development will be allocated for areas other than the research and development site.
Public liability insurance and bonds
Public liability insurance
The development of Crown Land creates a possibility for injury/loss resulting from interactions with aquaculture infrastructure as a result of trespass. Holders of Crown leases within the PCAFR will be required to obtain an appropriate public liability insurance policy covering the Crown lease site, as specified by the Secretary, DPI. The insurance policy must:
- be kept current for the duration of the Crown lease;
- be relevant to aquaculture activities within the lease site;
- provide minimum coverage to the value of A$10 million for each claim; and
- indemnify the State of Victoria, the Secretary DPI and their respective employees and agencies for personal injury, death and or property damage.
All Crown lease holders must provide evidence of a current insurance policy to the Secretary, DPI prior to deploying aquaculture equipment and annually thereafter. All licence holders must provide evidence of a current insurance policy to the Secretary, DPI prior to licence renewal or upon request.
The State is not at risk for personal liability or for product quality/recall provided that the relevant quality assurance programs are in place (including the VSQAP) and managed correctly. Accordingly, holders of aquaculture licences within the PCAFR will not be required to hold public liability insurance for product quality. However, it is suggested that holders of aquaculture licences producing product for human consumption hold an appropriate level of public liability insurance for product quality.
Cost of removal of commercial aquaculture equipment
Section 60A of the Fisheries Act provides for the removal of commercial aquaculture equipment within a specified time at the cost of the licence holder or general permit holder if "a person's authorisation to conduct aquaculture activities under an aquaculture licence or a general permit ceases". Ultimately it is the responsibility of the Crown lease holder to ensure all commercial aquaculture equipment is removed from the site at the expiration of the Crown lease. However, if the Crown lease holder is no longer financially viable at the expiration of the Crown lease and there is no current aquaculture licence held over the Crown lease site, it would not be possible for the State to recover the cost of removal of commercial aquaculture equipment. The following options aim to balance the cost of removal, and risk of abandonment of commercial aquaculture equipment with cost-effectiveness for industry while ensuring the State can recover the cost for removal of commercial aquaculture equipment from an aquaculture Crown lease site. Two options are available:
- bond option - lessees contribute annually to an indemnity fund calculated in accordance with the nature of equipment to be removed and the hectares under leasehold. The fund will be administered by Fisheries Victoria and the Government of Victoria may draw upon the fund to cover cost of removal of commercial aquaculture equipment and the interest from which is returned to lessees; or
- bank guarantee option - lessees may establish an individual bank guarantee for the purposes of removal of commercial aquaculture equipment, calculated in accordance with the nature of equipment to be removed and the hectares under leasehold.
Both options will be designed to accurately reflect the full cost of removing equipment, the risks of equipment abandonment relevant to the duration of the lease and, minimise the start-up cost for industry.
Fisheries Victoria, in consultation with relevant industry representatives, will determine an agreed option for recovering the cost of removal of commercial aquaculture equipment.
Exotic marine organisms
At present there are breeding populations of exotic marine species within PPB which have the potential to colonise commercial aquaculture equipment within the PCAFR. Management of these species is not the responsibility of the Plan.
The PCAFR will be developed in accordance with the SEPP and the requirements of the associated PPBEMP.
To assist in the early detection and eradication of incursions of new marine pests in the waters of PPB, it is important that where suspected such incursions are reported. Fisheries Victoria will develop an aquaculture licence condition requiring licence holders to report the presence of suspected exotic species on commercial aquaculture equipment.
In these cases the recommendations of the Interim Victorian Protocol for Managing Exotic Marine Organisms Incursions 1999 (or as updated) will be implemented by the DSE.
Implementation of the management plan
This Plan describes the management of the PCAFR with emphasis on ESD. The Plan has effect following its declaration by the Minister by notice in the Victoria Government Gazette. Implementation of the Plan will require actions by Government in respect of certain policy matters, by DPI in respect of day-to-day management, and by other stakeholders.
Key actions to be undertaken in the implementation of the Plan
The key actions to be undertaken to implement the recommendations of the Plan are listed and numbered below. Note that these tasks are not in priority order. A timetable for the implementation of these key actions is provided in Appendix 9. Many key actions must be completed prior to the allocation of sites, Crown leases or aquaculture licences. The purpose, process, timelines, outputs, outcomes and costs for the implementation of each of the key actions are detailed in Table 6. Note in this Table reference to cost is made on the basis that those key actions that will be implemented within the current Fisheries Victoria budget are referred to as 'within budget costs' (for example no additional funding is required).

Appendix 4: The Victorian Government response to the recommendations of the Final Report of the Environment Conservation Council's (ECC) Marine, Coastal and Estuarine Investigation (2000) for marine aquaculture in Victoria
R40. Commercial finfish aquaculture should not be considered in Port Phillip Bay until preliminary trials have been conducted under the following conditions:
- the trials are undertaken according to the nutrient reduction plan as outlined in clause 12, Schedule F6 (Waters of Port Phillip Bay) of the State Environment Protection Policy (Waters of Victoria); and
- a detailed monitoring program, including monitoring of the ongoing net nutrient balance, is carried out by the Department of Natural Resources and Environment.
Commercial operations should only be approved by the NRE after advising the Minister responsible for Fisheries and the Minister for Environment and Conservation that
- the trial demonstrates that commercial operations can be carried out with no net additional nutrient input to Port Phillip Bay; and
- a mechanism is developed, and put in place, to ensure independent monitoring of the ongoing net nutrient balance of commercial finfish aquaculture operations in the bay.
Schedule F6 (Waters of Port Phillip Bay) of the State environment protection policy (Waters of Victoria) requires the annual nitrogen load to Port Phillip Bay to be reduced by 1000 tonnes by 2006, and development of a Port Phillip Bay Environmental Management Plan and associated Nutrient Reduction Plan. Any finfish aquaculture proposals will be required to conform to the Nutrient Reduction Plan.
Within this context, the application of nutrient offset mechanisms (through the establishment of 'nutrient trading' whereby the addition of nutrients from one operation is offset by the removal of nutrients by another operation) will be investigated. In addition, as nitrogen is the key limiting nutrient for biological processes in the Bay, the focus of any offsetting/trading will be on nitrogen rather than other nutrients, such as phosphorus. Under any offset/trading scheme, purchasers of offsets will need to ensure best practice approaches are used to minimise nutrient inputs.
Commercial finfish aquaculture in Port Phillip Bay will only be considered if it can be demonstrated through peer-reviewed scientific research that nutrient management can be implemented successfully and without detriment to the environmental values of the Bay.
During the current review of the State environment protection policy (Waters of Victoria), EPA will consider including specific provisions in relation to waste minimisation requirements of aquaculture.
R41.
Each aquaculture area be subject to preparation of a management plan, including:
- specification of baseline and ongoing environmental monitoring requirements;
- access to the zone by other users;
- design, construction, maintenance and visual impact of structures; and
any additional requirements for individual areas noted in recommendations E1 to E12 below.
It is proposed that aquaculture zones be declared as fisheries reserves under Section 88 of the Fisheries Act 1995. As prescribed by Section 89 of the Act, a Management Plan must be prepared. The purpose of a Management Plan is to specify policies and strategies to ensure the ecological sustainable development of aquaculture zones. Accordingly the Management Plan will specify commitments to monitoring, public access, structural compliance and other requirements listed above (see R46).
R42.
Until the completion and approval of a Victorian Translocation Policy consistent with the National Policy for the Translocation of Live Aquatic Organisms, (Ministerial Council on Forestry, Fisheries and Aquaculture 1999), translocation of marine organisms for aquaculture be conducted according to interim translocation protocols or codes of practice, which should be publicly available. Preparation of the State policy and associated codes of practice should include public consultation.
NRE is developing a Victorian Translocation Policy, which will be released for public comment. In the interim, as a minimum standard NRE will continue to comply with the National Policy for the Translocation of Live Aquatic Organisms regarding translocation of marine organisms for aquaculture.
R43.
NRE expand existing and introduce new research and monitoring programs for existing and new aquaculture operations to include the following:
- assessment of changes in benthic species composition and abundance beneath aquaculture farms;
- monitoring for introduced species, pathogens, diseases, nutrient enrichment (particularly when supplementary feeding is used) and other potential ecosystem effects on the surrounding environment;
- an assessment of recovery times following cessation of aquaculture activities in an area;
- participation by the proponent in, and contribution to the cost of these programs; and
- publicly available reports.
Such detail will be outlined in the Management Plans for aquaculture zones, which will be released for public comment. The Management Plan will also give consideration to the indicators mentioned above, amongst others, and specify the frequency of public reporting.
R44.
Aquaculture operations which use supplementary food ensure that the food is tested and certified to be free from diseases, pathogens, other unwanted species, and therapeutic chemicals, subject to Import Risk Analyses (IRAs) to be developed by AQIS for processed aquatic animal feeds, aquatic meals and other aquatic animal products (see AQIS 1997).
Monitoring of imported product is the responsibility of Biosecurity Australia (formerly part of the Australian Quarantine and Inspection Service). Aquaculture operators will only be able to use imported product approved by Biosecurity Australia.
R45.
Conditions of aquaculture licences include provision for an instrument such as a performance bond to ensure that the operator undertake restoration of the site should the operation be abandoned or destroyed.
Recent changes to the Fisheries Act 1995 provide specific provision for the Secretary of NRE to require the clean-up of a site by the licence holder if that licence is cancelled or expired. This provision extends to the licence holder covering the costs associated with restoration of abandoned or destroyed aquaculture sites.
R46.
Other uses within licenced sites be allowed, except where they affect safe, secure and efficient aquaculture operations.
Aquaculture leases in zones are comparable to terrestrial commercial businesses. Public health and safety (ropes, surface obstructions, traffic etc.), operational efficiency and stock security are issues to consider when looking at multiple-use of these sites. In general, public access to aquaculture zones will be permitted but not to any declared lease areas.
Recommendation E: Aquaculture Zones:
The recommended areas shown on Map A (numbered E1 to E12) be made available for marine aquaculture subject to recommendations R41 to R46 above:
E1 Portland Aquaculture Zone
E2 Grassy Point Aquaculture Zone
E3 Clifton Springs Aquaculture Zone
E4 Point Lillias Aquaculture Zone (land-based)
E5 Avalon Aquaculture Zone (land-based)
E6 Bates Point Aquaculture Zone
E7 Kirk Point'Werribee Aquaculture Zone
E8 Beaumaris Aquaculture Zone
E9 Mount Martha Aquaculture Zone
E10 Dromana Aquaculture Zone
E11 Pinnace Channel Aquaculture Zone
E12 Flinders Aquaculture Zone.
The Government will support aquaculture initiatives subject to environmental assessment in each case. Existing and future marine aquaculture will be assessed under a management planning process, where planning and environmental controls will be established following community consultation. Aquaculture initiative funds over the last two years were aimed at facilitating industry growth. A review of the aquaculture initiative has recently been completed and endorsed by the Minister for Energy and Resources and will guide future Government commitment to aquaculture development.
All proposed aquaculture zones in Port Phillip Bay will be developed in accordance with Schedule F6 (Waters of Port Phillip Bay) of the State environment protection policy (Waters of Victoria).
The Kirk Point-Werribee Aquaculture Zone is located near the Western Treatment Plant. Any aquaculture proposal will need to be developed in accordance with requirements specified in the Werribee Segment of Schedule F6 (Waters of Port Phillip Bay) of the State environment protection policy (Waters of Victoria).
Appendix 5: Detailed description of the attributes of the Pinnace Channel Aquaculture Fisheries Reserve
The physico-chemical and biological features of the PCAFR have been assessed and described by the Marine and Freshwater Resources Institute and the ECC as part of characterisation studies of the area (ECC 1998, Barry and Bailey 2001; Coleman et al. 2001)11. The following description is a synopsis of this information.
Location
The PCAFR is comprised of two blocks located on either side of the Pinnace Channel where it flows from the Great Sands area (see Figure 1).
The sites are referred to as the northern and southern blocks and the coordinates are as follows.
Northern block | ||
---|---|---|
Datum GDA94 (Degrees and decimal minutes) | ||
South | East | |
North West | 38°14.257' | 144°48.864' |
North East | 38°13.910' | 144°49.979' |
South West | 38°15.693' | 144°49.581' |
South East | 38°15.347' | 144°50.697' |
Southern block | ||
Datum GDA94 (Degrees and decimal minutes) | ||
South | East | |
North West | 38°16.573' | 144°50.061' |
North East | 38°16.226' | 144°51.177' |
South West | 38°18.010' | 144°50.779' |
South East | 38°17.663' | 144°51.895' |
Both sites are rectangular (approximately 1.7 by 2.8 km each) and are 500 ha. The site location allows adequate separation from:
- major shipping activity, and
- the Port Phillip Heads Marine National Park (at the closest point the separation distance is 3.1 km).
Bathymetry
Both blocks have water that ranges from 15 to more than 20 m in depth (see Figure 2). The northern block comprises around 80 per cent of water at depths greater than 20 m. The southern block comprises around 20 per cent of water at depths greater than 20 m. The deepest area within either site is around 24 m.
Sediment characteristics
In the characterisation survey a total of 20 randomly allocated sites were analysed. The sediment is predominantly of very fine sand (0.06 to 0.125 mm) with some areas of fine sand (0.125 to 0.25 mm). The mud content of the sediment ranges from approximately 8 to 40%.
Sediment characteristics are related to depth, with grain size decreasing and mud content increasing as depth increases. Sandy, shallower areas at depth less than 20 m displayed a bedform dominated by mounds and depressions caused by Callianassid shrimps, while the muddy sediments of depth greater than 20 m displayed a flat profile (Coleman et al. 2001).
Sediment carbon content ranged from 1.4 to 5.6%, with carbon content decreasing with depth. Sediment nitrogen content ranged from 0.06 to 0.19%, and tended to increase with depth.
Benthic Fauna
The benthic fauna of PPB is rich in species diversity compared to similar embayments in other parts of the world. Although highly diverse, many species are scattered or infrequent in occurrence appearing at only a few sites (Poore 1992). The benthic fauna of PCAFR conforms to this general pattern with many species represented by relatively few individuals occurring at one or two sites. The characterisation survey identified 137 species, with the number of species per site ranging from 16 to 50 when benthic grab samples were passed through a 1 mm sieve. The number of individual specimens per site ranged from 54 to 519. The species diversity described approximates that of the 'intermediate sediments' as defined by Currie and Parry (1999).
Polychaetes worms most dominated benthic fauna accounting for over 45% of the individuals sampled with Lumbrineris cf laterilli, Marphysa sp, Nephtys inornata and Maldanid sp contributing 29%, 9%, 5% and 2% of the total individuals sampled respectfully. Other relatively abundant species were the crustacean Kalliapseudes sp (5% of individuals sampled) and the bivalves Chioneryx cardiodes (5% of individuals sampled) and Corbula gibba (an exotic bivalve, 2% of individuals sampled). The majority of the species were uncommon, with 92 species represented by less than 10 individuals and 69 species occurring at only one or two sampling sites.
Species diversity and density varied with depth, with greater species diversity and numbers of individuals at sampling sites at a depth 20 m or less (39 and 320 respectively) than at sampling sites greater than 20 m (25 and 110 respectively).
Sites at greater than 20 m depth were also characterised by a more even distribution of individuals amongst species. However, evenness was relatively high for all sampling sites, 0.55 to 0.86, allowing for the detection of opportunistic species associated with altered ecological conditions.

Epiflora and epifauna
Visual analysis identified occasional sparse Caulerpa sp beds along with beds of unidentified red alga, at depth 20 m or less. The depressions caused by Callianassid shrimps collected large quantities of drift algae, and when drift algae was absent, these depressions contained large quantities of broken shell rubble. Microalgal mats were not observed within the PCAFR.
Epifaunal diversity and abundance was low, with fourteen species identified in six video transects covering approximately 5.5 km of the seafloor. Previously only 20 species were recorded by divers within the area now defined as PCAFR (Cohen et al., 2000). Those species identified by divers, but not identified by video footage, are small and or cryptic and would be not easily detected by video. Abundance of epifauna was generally low with less than 10 individuals per 100m, with the exception of the ascidian Pyura stalonifera on sediments in 20m or less of water.
The ascidian Pyura stalonifera was the most common species, followed by the native flat oyster, the ascidian Cnemidocarpa etheridgii and the scallop. The abundance of many species varied between the shallow, sandy sediments (20m or less) and the deeper, muddy sediments (greater than 20m). The sandy sediments supported more of the ascidian Pyura stalonifera. The muddier sediments supported more sea cucumbers Stichopus mollis and scallop.
Current speed and direction
The predominant water currents are generated by tidal flushes that peak during ebb and flood tides12. Current directions are likely to be from the northnorth-east (flood tide) and the south-south-west (ebb tide). The area closer to the northern bank of the Great Sands may produce local current disturbances of variable direction and speed.
Both blocks are subject to daily tidal flushing that is likely to generate considerable mixing and exchange. On the flood tide waters flow in from Bass Strait, while on the ebb tide waters flow from the deeper, central PPB area. The regular flushing of southern PPB should ensure water quality within the PCAFR is maintained at a standard suitable for aquaculture.
A current meter was deployed at each block of PCAFR from mid December 2002 to mid February 2003. At the northern block, ebb and flood current speeds were broadly similar at about 0.10 to 0.15 m/s but occasionally peaked at 0.25 m/s. Peaks in current speed may be the result of intense weather events. The flood current direction was fairly stable at about north to north-north-east. The ebb current direction varied between west to northwest, that is towards Symonds Channel, and south-west to south-south-west, that is towards the Pinnace Channel. At the southern block, peak ebb and flood speeds were again similar but somewhat higher than the northern site, generally 0.10 to 0.25 m/s. Flood current direction was again more stable and mainly between north-north-east and northeast, while ebb current directions varied mainly between west and west-south-west.
Wind direction and wave climate
The most predominant direction for winds in southern PPB speeds is southerly which occurs 21% of the time followed by westerly at 15% of the time and northerly 14% of the time12. For winds greater than 30 km/h, the prevailing direction was southerly (7.6%) followed by westerly (7.4%), then south-westerly (6.3%) and northerly (6%).
The most common wind speed range was 20 - 30 km/h (34%) followed by the 30 - 40 km/h (21%) and 11 - 20 km/h (20%). Winds greater than 40 km/h occurred 16.7% of the time and winds 10 km/h or less occurred 7.0% of the time.
Wave heights at PCAFR were estimated using a wave generation model based on fetch lengths within PPB and historical wind data12. Using this model it was estimated the Northern Block experienced waves between 0.5 and 1.0 m 46.9% of the time and waves greater than 1.0 m 7.9% of the time. At the Southern Block waves between 0.5 and 1.0 m occurred 39.5% while waves greater than 1.0 m height occurred 7.8% of the time. The highest waves came predominantly from the north quadrant, primarily a result of this quadrant having the greatest fetch length (approximately 30 km). In addition, some of the strongest winds affecting PPB are from this quadrant.
These data are consistent with the wave climate data compiled for the VRCA in 1974/5 from the nearby Rosebud area of PPB which has a similar fetch length. These data showed a worst case scenario in that year of a maximum wave height of 1.6 m with a period of 4.5 seconds. It is worth noting that waves in excess of 1 m were recorded less than 5% of the time.
Water quality
Water quality within the PCAFR is important to provide an environment to promote the growth of the target species and to ensure harvested stock are suitable for human consumption.
Water quality parameters for growth include temperature, salinity and primary productivity. Temperature were recorded at the site from August 2000 to February 2003 and ranged from 9.9 to 22.1°C. Between August 2000 and August 2001 temperature data was available from both the PCAFR and the Western Channel marker. There was an excellent correlation between the two data sets. The ten year data set from the Western Channel marker indicates that temperatures in the PCAFR are likely to be predominantly between 10 and 22°C.
There are no salinity data available for the PCAFR, however salinity data at a depth of 3 m is available from the Western Channel marker (near Symonds Channel). Salinity at this site varied from 30.4 to 35.5 parts per thousand over an 8 year period.
The concentration of phytoplankton in the waters of the PCAFR is important for the growth of filter feeding bivalve shellfish. The southern end of PPB generally has lower levels of chlorophyll a reflecting a lower concentration of phytoplankton for the area, however good currents in the region may assist nutrient availability to shellfish.
Water quality parameters that impact upon the production of shellfish for human consumption include microbiological contamination and algal blooms. Faecal coliforms of mammalian origin pose a threat to shellfish quality generally when flushed from terrestrial sources into shellfish harvesting areas. There has been very little bacterial sampling in the vicinity of the PCAFR. Based on strong daily tidal exchanges and other findings in the south of PPB (for example Capel Sound) there is little risk of contamination by faecal coliforms from land based sources within the PCAFR. Given the lack of sampling in the PCAFR, potential impacts from the Mud Islands require further investigation.
The high flushing rates and high exchange with Bass Strait water is considered to also decrease the risk of algal blooms within the PCAFR. As a result the PCAFR is consider to be a low risk site with regard to algal blooms and in particular the 'bitter taste' blooms that have a serious impact on mussel farming in other areas of PPB. The VSQAP will monitor the phytoplankton species at the PCAFR for the presence of any problem/nuisance species and appropriate management will be implemented to protect human health and product quality.

5 Wave, current and temperature data for the Pinnace Channel Aquaculture Fisheries Reserve are available at www.depi.vic.gov.au.
6 Compliance points are those specific locations within Crown lease/aquaculture licence sites at which survey data and or samples will be measured/collected, typically along a specific transect. Reference sites are effectively compliance points which are located outside the lease/licence site at a predetermined location and designed to be used as 'controls' to clarify the extent of environmental impacts attributable to aquaculture activity within the Crown lease/aquaculture licence site.
7 'Artificial Feeds' includes pelleted formulated feeds, whole/trash fish and by-products used for aquaculture purposes.
8 Nutrient offset mechanisms may be established whereby the addition of nutrients from one operation is offset by the removal of nutrients by another operation.
9 Buffer zones when required will be designed to ensure impacts attributable to aquaculture activity are contained within the reserve
10 'Longline backbone' is the length of longline backbone (headline) that is available for the attachment of production substrate. No differentiation will be made between the length of single or double backbone longline.
