Age Reading Demonstration (ARD)

Want to try your hand at ageing fish bones? Try our interactive fish ageing program. Click on the species you want to start with to begin ageing, then click on the otolith image where you see annular marks. Submit the marked image. ARD will automatically mark the image with marks from an experienced age reader, and compare your age with the experienced age reader's age.
