Cayman's environment department identifies Nassau grouper by AI facial recognition
Cayman Islands Department of Environment — The Cayman Islands Department of Environment now runs AI fish identification on the Nassau grouper aggregation off Little Cayman, shooting as many photographs as possible across three or four days for software that reads every marking. Croy McCoy, research manager at the Research and Assessment Unit, said postgraduates once tallied each grouper by eye on footage, hours of labour that facial recognition software absorbs while matching this year's arrivals against earlier ones. That evidence feeds the Grouper Moon Project, run with the Reef Environmental Education Foundation on an endangered species since 2001; a multi-agency crew returned in February 2026.
