Atlantic salmon farm, Pacific Northwest, Canada
View through the net wall of Atlantic salmon being farmed in a pen in the Pacific Northwest. Atlantic salmon (Salmo salar) is farmed all around the world, in both the Atlantic and Pacific Oceans. There are concerns that escapes of non-native fish may upset the balance of the ecosystem in the Pacific region. The high density of the farmed salmon in the pens also encourages diseases, especially salmon lice, which can easily escape the open pens and infect wild fish. From 2021, most non-native salmon farms were banned in the Pacific Northwest Coast region, but many still remain active.
