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 is based on the Russian common name chavycha (чавыча).
Chinook 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. They have been introduced to other parts of the world, including New Zealand and the Great Lakes of North America. A large Chinook is a prized and sought-after catch for a sporting angler. The flesh of the salmon is also highly valued for its dietary nutritional content, which includes high levels of important omega-3 fatty acids. Some populations are endangered, though Chinook salmon have not been assessed for the IUCN Red List.(Source: Wikipedia.org)
The term “salmon” refers to a variety of species that are all “anadromous” fish, which means they are born in fresh water rivers and streams, migrate to the ocean to mature and spend much of their adult life, and then return to the streams and rivers in which they were born to spawn (reproduce) and then die. Six types of salmon are consumed in the United States including: Atlantic, Chinook, Chum, Coho, Pink, and Sockeye Salmon. Of these, five species (Chinook, Chum, Coho, Pink and Sockeye) are harvested from wild fisheries in the Pacific Ocean and one type, Atlantic salmon, is primarily farmed raised.
All types of salmon provide a good source of high quality protein and the heart healthy omega-3 fatty acids. The fat and omega-3 content varies from one species to another. Total fat content ranges from approximately 4 to 11 grams per 3 ounce cooked serving. Omega-3 fatty acid content ranges from 700 to 1,800 milligrams of omega-3 fatty acids per 3 ounce cooked serving.
A summary of the fat and omega-3 content of the six commercially important salmon species is provided in the chart below. Salmon is also a good source of a variety of vitamins and minerals. Canned salmon that contains bones is also a good source of calcium.
