The Chinook salmon (Oncorhynchus tshawytscha) is the largest species in the Pacific salmon genus Oncorhynchus. The common name refers to the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, spring salmon, and Tyee salmon. The scientific species name, tshawytscha, is based on the Russian common name chavycha (чавыча). Chinook salmons are anadromous fish native to the North Pacific Ocean and the river systems of western North America, ranging from California to Alaska, as well as Asian rivers ranging from northern Japan to the Palyavaam River in the Arctic north-east Siberia. Order: Salmoniformes, Family: Salmonidae, Species: Oncorhynchus tshawytscha (Walbaum, 1792)
