Etymology: Sebastes: Greek, sebastes = august, venerable (Ref. 45335).
Environment / Climate / Range
Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 100 - 1000 m, usually 100 - 500 m (Ref. 35388). Temperate; 3°C - 7°C (Ref. 35388); 79°N - 38°N, 94°W - 71°E (Ref. 54885)
Length at first maturity / Size / Weight / Age
Maturity: Lm 38.2, range 38 - 41 cm
Max length : 100.0 cm TL male/unsexed; (Ref. 4570); common length : 45.0 cm TL male/unsexed; (Ref. 4570); max. published weight: 15.0 kg (Ref. 35388); max. reported age: 60 years (Ref. 35388)
Eastern Atlantic: Kattegat and North Sea, northward to Spitsbergen, southern part of Barents Sea eastward to Kanin Banks and Novaya Zemlya, rare in White Sea, Iceland and eastern Greenland. Western Atlantic: Greenland and southeastern Labrador in Canada to New Jersey in USA (Ref. 7251).
Found off the coast from 100-1000 m; juveniles found in fjords, bays and inshore waters. Normally trawled in deep water (Ref. 9988). Benthic (Ref. 5951). Feed mostly on euphausiids in summer; herrings in autumn and winter; capelins, herrings, euphausiids and ctenophores in spring. Gregarious throughout life. A slow growing species (Ref. 9988). Ovoviviparous, gonads of male and female do not mature at the same time. The spermatozoa are kept in the ovary of the female after copulation until such time that the eggs ripen paving the way for fertilization (Ref. 74488). Copulation takes place in late summer or early autumn (Ref. 35388, 34817); in winter females give birth to 50,000-350,000 pelagic larvae of 8 mm length (Ref. 35388). Utilized fresh and frozen; eaten fried, broiled, microwaved and baked (Ref. 9988).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00610 - 0.01884), b=3.06 (2.90 - 3.22), based on LWR estimates for species & Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.0 ±0.68 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (rm=0.23; K=0.06-0.08; tm=10-12; tmax=60; Fec= 19,000-350,000).
Vulnerability (Ref. 59153
