Commercial salmon farms producing coho, Oncorhynchus kisutch, and chinook salmon, O. tshawytscha, have been established at several sites within central and southern Puget Sound, Washington.  From an experimental salmon farm in 1971–72 that produced 60 metric tons of pan–size fish, the industry has grown in 1973–74 to a production estimated at 350 metric tons.  Although the technical feasibility of saltwater pen culture has been demonstrated, certain problems hinder economic viability.  The major constraints are disease, availability of feeds and saltwater farm sites, institutional barriers (laws and regulations), and knowledge of saltwater husbandry.
