Chinook Salmon are anadromous – they hatch in freshwater streams and rivers then migrate out to the saltwater environment of the ocean to feed and grow. When in the ocean, Chinook Salmon are blue-green on the back and top of the head with silvery sides and white bellies. Young Chinook Salmon feed on terrestrial and aquatic insects, amphipods, and other crustaceans; older Chinook primarily feed on other fish. Image courtesy of NOAA.
