Over 54 million salmon died in Norwegian fish cages last year, and the total loss amounted to 67 million farmed salmon, according to the Norwegian Directorate of Fisheries. This corresponds to a loss of 16-18 per cent, according to the Norwegian Institute of Marine Research.
A mysterious salmon disease discovered in the Norwegian Enningdalsälven, on the border with Tanum municipality in Västra Götaland, is causing concern. The disease, Red Skin Disease, manifests itself as skin bleeding, fungus, and sores on the fish's belly, causing the salmon to rot alive.
