Atlantic Salmon (Salmo salar) are an exotic species that are occasionally found in Washington waters.
They are commercially grown in sea-water net pens in Puget Sound and in some freshwater hatcheries as well. Occasionally some of these fish will escape from their holding pens and may be caught by anglers in fresh or saltwater.
