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

Arctic to Northwest Atlantic, and Northeast Atlantic: Port Barrow, Alaska to West Greenland, then south along Canadian coast to the Miramichi, Gulf of St. Lawrence and Cape Breton Island. Northeast Atlantic: a disjunct population in the White Sea exists. The stock has been strongly reduced in recent years.

Biology     Glossary (e.g. epibenthic)

Non-schooling (Ref. 28073). Lives close to the coast and is rarely found offshore, in deeper water (Ref. 1371). Benthic, shallows and deepwater to 400 m (Ref. 58426). Feeds on fishes (capelin, polar cod, smaller Greenland cod and Greenland halibut (Ref. 5951)), shrimps, crabs, euphausiids, squids, polychaetes, and echinoderms. There is probably competition between this species and Gadus morhua (Ref. 1371). Over 12 nucleotide substitutions in the 307 base pair region of the mitochondrial cytochrome b gene differentiate this species from Gadus morhua (Ref. 40214).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00448 - 0.01409), b=3.07 (2.91 - 3.23), based on LWR estimates for species & (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.2 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=3-4; tmax=12).
Vulnerability (Ref. 59153):  High vulnerability (57 of 100) .
low
Price category (Ref. 80766):   Low.
