Salmon farming is a type of aquaculture where the fish are grown in net cages, typically located in sheltered bays and fjords along the coast. Salmon are hatched in brood hatcheries and grown in freshwater until they are large enough to transfer to marine pens.
Salmon farming is associated with numerous environmental concerns, including water pollution, chemical use, parasites and disease. Wild salmon from Alaska come from a well-managed fishery and are low in contaminants. There are five species of wild salmon from Alaska: chinook, chum, coho, pink, and sockeye. All come from well-managed fisheries and are low in contaminants. Arctic char, a member of the salmon family, comes primarily from eco-friendly farms.
