November 7, 2019 — Farmed salmon company Lerøy Seafood Group has launched a pilot project in Norway that would attach sensors directly to the bodies of salmon in cages, then use an underwater wireless network to capture data in real time from the sensors about fish behavior and transmit it to farm managers on the water’s surface.
The technology would be a major advance from current monitoring systems, which can’t directly measure fish health in the water, and would give salmon farmers the kind of detailed information about the fish in their cages that so far has eluded them.
