Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 0 - 825 m (Ref. 6793), usually 165 - 293 m (Ref. 27437). Deep-water; 64°N - 24°N, 143°E - 110°W (Ref. 54884)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

North Pacific: Honshu, Japan to Cape Navarin in the Bering Sea (but not in the Sea of Okhotsk) and La Jolla, California, and along the Aleutians from Stalemate Bank and Bowers Bank to the Alaska Peninsula. Stocks have suffered severe population decline due to overfishing (Ref. 27437).

Length at first maturity / Size / Weight / Age

Maturity: Lm 33.2, range 25 - 43.3 cm
Max length : 53.0 cm TL male/unsexed; (Ref. 56527); max. published weight: 2.1 kg (Ref. 56527); max. reported age: 103 years (Ref. 93933)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 14 - 17; Anal spines: 3; Anal soft rays: 6 - 9; Vertebrae: 26. Head spines weak - nasal, preocular, supraocular (may be absent), postocular, tympanic, parietal, and nuchal (may be absent) spines present, coronal spine absent (Ref. 27437). Long lower jaw with prominent forward directed symphyseal knob (Ref. 27437). Posterior margin of caudal indented (Ref. 6885). Bright to light red, usually with dark markings dorsally, may have some dark stippling on sides and dark blotch on caudal peduncle (Ref. 27437).

Biology     Glossary (e.g. epibenthic)

Abundant in offshore waters (Ref. 2850). Young pelagic up to age 3 (Ref. 6885). Grows slowly (Ref. 2850). Viviparous (Ref. 34817). Very important commercial rockfish in the North Pacific (Ref. 2850, 27437). Marketed as fillets (Ref. 2850). Utilized fresh and frozen; eaten fried, microwaved and baked (Ref. 9988).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Produces young in small numbers, only about 300,000 when the fish is 20 years old.

Estimates based on models

Preferred temperature (Ref. 123201): 1.1 - 6.4, mean 3.8 °C (based on 124 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00779 - 0.01118), b=3.09 (3.05 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.3 se; based on diet studies.
Generation time: 8.3 (7.8 - 10.4) years. Estimated as median ln(3)/K based on 33 growth studies.
