Want to try your hand at ageing fish bones? Check out our interactive fish ageing program tool. With this tool you can determine how old a fish is by counting otolith (fish ear bones) rings. This is similar to determining the age of a tree.
This interactive tool offers you an opportunity to try your hand at ageing and learn more about the following fish species.
