Age and weight estimator for fish
Our scientists have developed a ‘calculator’ to help recreational anglers estimate the weight and age of fish they catch.
It’s based off thousands of fish records, collected over decades, for these species:
- Australian bass
- Black bream
- Estuary perch
- Golden perch
- Murray cod
- Dusky flathead
- Sand flathead
- King George whiting
- Brown trout
- Rainbow trout
Just select the species, enter the fish’s length and the calculator will do the rest. Easy!
For example, a 55cm snapper weighs a little over 2kg and is about 7 years old while a 35cm black bream comes in at 770 grams and around 17 years old.
