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
