About Arctic Offshore Farming

Arctic Offshore Farming is a pioneering project within offshore fish farming. Developed with an uncompromising focus on fish health, the offshore cage and its technological solutions aim to solve the most common challenges in the aquaculture industry. Arctic Offshore Farming is dimensioned and built to withstand the hardy weather conditions offshore – where the salmon have their natural habitat.

Arctic Offshore Farming is a submergible offshore cage which emphasises good fish health. The biggest innovation is four artificial breathing surfaces under water, equivalent to 10 % of the cage’s surface area, giving access to fresh air when the cage is submerged. Here, the salmon can jump in air and light as if it were on the surface, whilst the submerged offshore cage keeps salmon lice in the upper layers of water at a distance. The result is the next generation of offshore cages, emphasising fish health whilst keeping environmental impact at a minimum.
