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).

Biology     Glossary (e.g. epibenthic)

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).

Bayesian length-weight: a=0.01072 (0.00610 - 0.01884), b=3.06 (2.90 - 3.22), based on LWR estimates for species & Subfamily-BS (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).
