CageEye autonomous fish feeding from Bluegrove
- Published 18 November 2022; updated 21 September 2026; 2-minute read. CageEye’s Echofeeding system uses hydroacoustic sensors to observe fish biomass regardless of visibility, then machine-learning models estimate appetite and adjust feeding automatically, with a human operator overseeing the system. The plug-and-play hardware is described as self-cleaning, suitable for remote use and compatible with external feeders and existing camera systems.
- The page says appetite-based feeding can improve growth, fish health and welfare, reduce wasted feed and environmental impacts, and provide data to evaluate/predict feeding operations. Echofeeding is reported in use in Canada, Chile, the Faroe Islands, Iceland and Norway, including at three of Norway’s four largest salmon farmers. CageEye is part of Bluegrove, which was expanding into other species and markets.
- The article cites a precision-aquaculture market estimate of USD 398 million in 2019 and projection of USD 764 million by 2024; this forecast is past-dated. Linked UN SDGs: 2, 12 and 14.
