Bluegrove presents autonomous feeding solution at AquaSur 2022

During AquaSur, on March 2 to 4 in Puerto Montt, Chile, Bluegrove will present an autonomous feeding solution that helps salmon farmers increase fish growth while improving feed conversion rate and animal welfare in aquaculture. 

Bluegrove’s autonomous feeding solution will be presented at the booth, located at B101. Visitors can watch the online feeding dashboard, experience real-life feeding sessions and look at the hydroacoustic sensors that are being used to monitor the movement of fish in cages.  

Visitors will be demonstrated a system that makes its own feeding decisions about when and how much to feed the fish based on different data inputs, specific farm setups and objective analysis of fish appetite. 

Hydroacoustic sensors accurately observe how fish in cages move and school, which means the appetite-based decision engine will know exactly when the fish are hungry and when to end the meal. This helps the autonomous feeding machine understand the fish so as long as they’re hungry it will respond by providing feed.

The hydroacoustic sensors, used to collect data from the cage, are low-maintenance and work independently of light or visibility. While a camera sees about 1 to 3% of the cage, hydroacoustics observe about 70% of the entire cage.

Autonomous feeding is the future of feeding fish in cages. Bluegrove’s feeding system is already being used by salmon farmers in Chile and Norway. 

Technical talks

On Thursday March 3, at 11.30 – 12.15 our experts Dr. Sunil Kadri and Ole Fretheim will give a presentation on how hydroacoustics and machine learning technologies can be used to optimize feeding. This talk is followed by a presentation of our colleague Haakon Lund, who will explain the use of the underwater aeration system called Mid-Norwegian Ring to improve the water quality in cages.
