Robo-turtles in fish farms reduce fish stress
A sea cage can hold up to 200,000 farmed salmon. If the cage is damaged, such as by a hole in the nets, the fish could swim out through the opening and escape in short order.
Clearly, the aquaculture industry wants to avoid this scenario. Not only do escapes lead to large losses for the industry, but we also don’t want farm-raised salmon to mix and interbreed with wild populations.
