Marine; brackish; benthopelagic; non-migratory; depth range ? - 1280 m (Ref. 50550), usually 30 - 400 m (Ref. 54255)

Climate / Range

Polar, preferred 5°C (Ref. 107945); 68°N - 34°N, 129°E - 120°W (Ref. 54255)

Distribution

North Pacific: from Kivalina, Alaska, to the southern Sea of Japan and to Carmel, California, USA. The occurrence off the northern part of Baja California (Mexico), as reported from Quast and Hall, (1972) (Ref. 6876) is apparently erroneous.

Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 38-48; Anal spines: 0; Anal soft rays: 33 - 42. The dorsal fins are widely separated. The pelvic fins have a slightly elongated filament. The lateral line is continuous to about the back end of the first dorsal-fin base; it is interrupted at the read of the body. On the head are lateral line pores. Body color is olive green to brown on the back and becomes silvery on the sides and pale ventrally, often with mottled patterns or blotches.

The adults usually live near to the sea floor, but sometimes they also appear near the surface (Ref. 1371). They perform diurnal vertical migrations (Ref. 1371). They mainly feed on krill (Ref. 39882) but they also eat fishes and crustaceans (Ref. 6885). The adults which are spawning are often solely captured for their roe. The meat is used to produce surimi (this is an imitation of shellfish meat) (Ref. 28499). They are traded as fresh fish, boneless flesh, in frozen blocks or as surimi. The fish is cooked in the microwave, steamed or fried in butter (Ref. 9988).
