|A Pacific fish (in rivers from Kamchatka, through Alaska to California. Incidental migrations to rivers of Shiribetsu and Yurapu of Hokkaido have been reported), introduced into northern rivers of France; in 1973 and 1974, 50,000 yearlings escaped into the Varenne (Normandy) from a fish farm, and 10,000 in 1975, with lesser numbers in southern France and southern Brittany in 1976-79; in 1975-77 up to 25 adults were caught in the Varenne, in rivers to the north, and around the Channel Is. Also introduced to the Great Lakes of America, Argentina, and Chile.|
|Habitat and Biology|
|Anadromous, adults enter rivers from autumn to winter and spawn about 2,500 to 7,000 eggs in headwaters. Fry emerge from bottom gravel in spring, spending about one year in the river.
Instead of territorial behavior in the parr, the smolt make schools and are carried out to sea. Young fish remain close to shore. Immature migrate more than 1600 km offshore.Main food items are insects in the river, small fishes such as sandlance and herring and many crustaceans near shore, and squids and krill in the open ocean.After 1 or 2 years of at sea, adults return to the river.|
|To about 88 cm and 14 kg; usually to around 3.6 kg at which weight it measures around 50-76 cm.|
|Interest to Fisheries|
|Caught by gillnets and trawl nets. The total catch reported for this species to FAO for 1999 was 15 466 t. The countries with the largest catches were USA (13 259 t) and Russian Federation (1 668 t).|
