Want to try your hand at ageing fish bones? Try our latest interactive fish ageing program: ARD 3.0. To get started, click on the link to ARD 3.0 and select a 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.
