Automated otolith aging using image processing [2024 INV#WO0000000109315]

Low riskExact public inventory row

Description

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).

Detailed example

automated aging process

AI / analytics pattern

Classical/Predictive Machine Learning: Models trained on data to make predictions or classifications based on identified patterns or relationships.

Automation level / stage

b) Pilot – The use case has been deployed in a limited test or pilot capacity.

Expected benefit

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

Controls / human review

ATO: No; PIA: Not published

Data needed

Otolith images (pictures) with known ages
