Alaska State Fish

King Salmon (common name)
Oncorhynchus tshawytscha (scientific name)


Alaska’s state fish, the chinook salmon, is called the king salmon because it is the largest species of salmon. Individuals reach over 100 pounds. The king is native to the Pacific Coast of North America. Its coloration is a variable pattern of mottled blue-green, with silver flanks, black spots on the tail, and black around the mouth. When it spawns, reddish patches develop on its flanks and its nose becomes hooked. The chinook is migratory. At one to six years of age, adult chinook travel from the ocean back to the streams in which they were born in order to lay eggs. Once hatched, the salmon typically migrate to estuaries and then go out to sea after three months.  A small number of male chinook, called "jack salmon," spend two years in freshwater before migrating to the ocean or just turn around after a few months at sea and return to freshwater.  The salmon is one of the most popular edible fish in the world, eaten raw, smoked, marinated, or cooked. The king salmon was adopted as the official state fish of Alaska in 1962.
