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

Eastern Atlantic: Svalbard to west coasts of Scotland and Ireland, deeper parts of North Sea and across the Wyville Thomson ridge to Denmark Strait. Western Atlantic: Davis Strait to George's Bank in Canada.

Biology     Glossary (e.g. epibenthic)

Bathypelagic (Ref. 58426). Prefer depths of 182.8-255.9 m, temperature 7-10°C and mean salinity 34 ppt (Ref. 5951). Probably form schools close to the bottom. Feeds on planktonic invertebrates including euphausiids, amphipods (arrow worms, krill and Thermisto (Ref. 5951)), chaetognaths, squids and ctenophores, also small fishes. Spawns from April to July (Ref. 4773). Growth is slow. Eggs and young are pelagic at depths of 400-500m. Used fresh or in fish meal production (Ref. 35388).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00232 - 0.00785), b=3.16 (2.99 - 3.33), based on LWR estimates for species & (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.3 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.12-0.14; tm=5-9).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (51 of 100) .
Price category (Ref. 80766):   Very high.
