Reference Collections For Age Determination Of Select Northwest Atlantic Species

February 28, 2020

The Fishery Biology Program has photographs of our reference collections (known-age fish) for various species. Currently, there are images available for Atlantic cod, haddock, and American shad.

These collections of otoliths images may be used as a training resource or to measure the accuracy of age estimates. These images are of fish for which the age is reliably known. Both annotated and unannotated images are available. 

We are working to assemble image collections for additional species. Please contact Eric Robillard for more information.
