Stingray Marine Solutions reports that over 3,500 of its underwater robots now operate at Norwegian salmon farms, protecting over 112 million fish. Deployments increased by about 1,000 over the last year, according to the company's latest annual report, as reported by Tom's Hardware.

The systems use AI to identify sea lice and target them with lasers while fish swim in their pens, providing an alternative to chemical baths. They operate continuously and protect 20-25% of Norway's farmed salmon. Up-front deployment costs remain a drawback, and the systems work best preventatively: lice can accumulate in darker, murkier corners and beyond the robots' operating area.
