New Research Illuminates the Needs of Farmed Salmon

Scientists in Norway have begun examining how farmed salmon and rainbow trout perceive the light in their environment. Their aim is to provide recommendations to fish farmers on the use of lighting from hatching to harvest for both species.

Light control is widely used in aquaculture to promote healthy growth, synchronise smoltification, and prevent early sexual maturation. This is achieved by adjusting the intensity, quality, and timing of the light surrounding the fish.

By now considering the light environment from the fish’s perspective, the scientists intend to recommend light regimes that are optimally adapted to the biology of the fish at all times.
