Details

This system uses computer vision and deep learning to automatically estimate the age of salmon by analyzing scale imprint images. It is designed to assist technicians at Fisheries and Oceans Canada's Sclerochronology Lab, which processes approximately 80,000 salmon scale aging assessments per year across British Columbia and the Yukon. The system does not process personal information and is currently in development. Its use of AI has been disclosed.
