背棘 (總數) : 0; 背的軟條 (總數) : 10 - 13; 臀棘: 0; 臀鰭軟條: 18 - 23; 脊椎骨: 65 - 72. Distinguished by the large canine teeth on the vomer and 18 to 23 rays in the anal fin (Ref. 27547). Adipose fin sickle-shaped; paired fins longer in males than in females; all fins with well developed breeding tubercles in ripe males which are poorly developed or absent in females (Ref. 27547). Adult coloration is brown to blue on back and top of the head, the sides lighter to silvery white, and the ventral surface white; speckling is fine, sparse and restricted to the back; peritoneum is light with black speckles (Ref. 6885). Fins transparent, pectorals and caudal often dusky (Ref. 27547). During spawning, male fish has a distinctly raised ridge along the middle of the body and a rough texture, differentiating it from the female which is smaller, smoother and shinier.

Found near shore and in coastal inlets and rivers (Ref. 2850). Possibly to 625 m depth (Ref. 6793). Spends most of its life in the sea, returning to freshwater streams to spawn (Ref. 27547). There is evidence of return to natal streams (Ref. 10276). May migrate up to 160 km upstream. Feeds on plankton and only while at sea (11699, 10276). Excellent food fish and source of oil (15% body wt.). Anadromous (Ref. 96339).

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚

The spawning run from the sea to freshwater streams begins when river temperature rises to about 4.4° but the fish stop running if temperature exceeds 7.8°C. Males predominate the early part of the run, but their numbers are equalled or exceeded by females later (Ref. 10276, 11699). Adults usually die after spawning but some move back to the sea and return to spawn a second time (Ref. 1998). Upon hatching, larvae are found near the bottom and are soon carried downstream to salt water and eventually found in the scattering layer of coastal waters (Ref. 27547).北太平洋: 在白令海 , 與樹蔭處的位於聖徒馬修島西方與 Kuskokwim 海灣在阿留申群島中岸堤到蒙德勒海灣，美國加州。來自卑詩省北部的族群是與那些在菲沙河分開.(參考文獻 10276)
