Problem the AI is intended to solve

Fisheries managers and researchers often need to know the age of fish for population estimates, stock assessment, and similar projects. Fish otoliths (an ear bone) often accumulated rings annual (similar to tress).

Expected benefits

automate this process to see if we can reduce variability across individual agers and automate the aging process of counting otolith rings possibly saving time
