Family
Salmonidae
Description: Medium-to-large, torpedo-shaped fish. Powerful swimmers. Most salmonids are anadromous, spending adult life in salt water and returning to breed in freshwater streams. Breeding adults undergo radical changes in color when entering fresh water; males develop a hooked jaw, large canine teeth, and a 'razor back'. Juvenile salmon need estuaries for transition to salt water for early growth. Locally, all five major salmon species can be found: Chinook ('King'- 70 lbs, 52 in/1.3 m), Chum ('Dog'- 9 lbs, 40 in/1.02 m), Coho ('Silver'- 6-12 lbs, 38 in/.96 m), Sockeye ('Red'- 5-7 lbs, 33 in/.83 m), and Pink ('Humpback'- 4-6 lbs, 30 in/.76 m).
Food: Predators- feeding on small crustaceans, aquatic insects and smaller fish.
Reproduction: Spawning females dig redds (shallow nests) in bottom gravels; lay small, round eggs that males fertilize with milt (sperm); and cover eggs with gravel. Pacific salmon die soon after mating. Eggs spend two to five months in stream-bed gravel.
Fun Facts: Largest chinook ever known was found in Alaska in 1946; it was 125 lbs.
