The Atlantic Salmon
Atlantic salmon (Salmo salar) have been a part of salmon farming in Norway since the 1960's and in British Columbia since the early 1980's. The Atlantic salmon is actually a trout and more closely related to Rainbow trout than Pacific salmon. It follows an anadromous migration pattern, and spends most of its adult stage in saltwater, returning at maturity to lay eggs in freshwater rivers. The freshwater phase may last 1 to 4 years and the time spent in saltwater will also vary from 1 to 4 years. The Atlantic salmon is also iteroparous, meaning the adult spawner may not necessarily die after spawning and may recondition itself to spawn another year. In this respect, the Atlantic salmon is similar to the steelhead prized by sport fisherman in the Pacific Northwest.
The Atlantic salmon is an outstanding fish for salmon farming, as they grow quickly and have the fresh fish quality consumers are looking for.
