Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; demersal; depth range 0 - 700 m (Ref. 50593), usually ? - 91 m (Ref. 2850). Temperate; 67°N - 35°N, 130°E - 125°W (Ref. 54599)
North Pacific: Korea and the Sea of Japan to the Sea of Okhotsk, Bering Sea, and Barkley Sound, Canada. Reported from the Alaskan Beaufort Sea (Ref. 28503).
Length at first maturity / Size / Weight / Age
Maturity: Lm 27.3, range 21 - 32 cm
Max length : 49.0 cm TL male/unsexed; (Ref. 56370); common length : 33.5 cm TL male/unsexed; (Ref. 4883); max. published weight: 1.7 kg (Ref. 56527); max. reported age: 34 years (Ref. 55701)
Adults feed on hydroids, worms, mollusks, and brittle stars (Ref. 6885). Marketed frozen and eaten fried, microwaved and baked (Ref. 9988).
Each individual spawns from 8 to 11 batches (Ref. 39301). Spawning occurs primarily in shallow water but for large females spawning may take place in waters to a depth of around 50 m (Ref. 119537). Undergoes spawning and feeding migration (Ref. 119537).
