Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 8 - 9; Radios blandos dorsales (total) : 28 - 38; Espinas anales: 1 - 2; Radios blandos anales: 22 - 33; Vértebra: 23 - 25. Small specimens may have an additional forward-directed spine at first dorsal origin (embedded in larger specimens).
Body shape (shape guide): fusiform / normal.
Adults are often found offshore, up to 500 miles from the coast (Ref. 9283). Are considered as one of the straddling stocks in the northeast Pacific (Ref. 87829). They form large schools (Ref. 2850). Young frequently occur in school near kelp and under piers (Ref. 2850). They feed mainly on small crustaceans and fish larvae (Ref. 9283). Large individuals often move inshore and north in the summer (Ref. 2850). Marketed fresh, smoked, canned and frozen; eaten fried, broiled and baked (Ref. 9988).
