Also know as King Salmon, Oncorhynchus tshawytscha, is the largest of the Pacific anadromous salmon. The largest King landed to date weighted 125 pounds and measured 58 inches in length. These kings of the ocean range from Alaska to Baja California, with abundances schooling in the Sacramento and Columbia River confluences with the Pacific. These fish return to their place of birth, sometimes far up-steam of the ocean, to spawn and die. Chinook can live to be five years old before spawning.
