Columbia River Chinook
Columbia River estuary · Pacific County · Upper Columbia spring-run listed endangered 1999
Chinook are the largest Pacific salmon. NOAA lists several Columbia River populations as threatened or endangered, and they are primary prey for Southern Resident killer whales.
Chinook salmon, Oncorhynchus tshawytscha, are also called king salmon. NOAA Fisheries says they are the largest of the Pacific salmon. They can grow as long as 4.9 feet and up to 129 pounds, though typical mature fish are about 3 feet and 30 pounds. They hatch in freshwater, feed in the ocean, and return to natal streams to spawn.
Several Columbia basin populations are protected under the Endangered Species Act. NOAA lists Lower Columbia River Chinook as threatened (May 24, 1999) and Upper Columbia River spring-run Chinook as endangered (March 24, 1999). Snake River fall-run Chinook are also listed as threatened. NOAA says salmon are primary prey for Southern Resident killer whales.
