Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. Gray-brown dorsally, silvery on sides, white on belly. A dark blotch is at the upper edge of the pectoral-fin base.

Benthopelagic to pelagic over muddy bottoms. Mostly found between 100 and 200 m. Feeds mostly on planktonic crustaceans (copepods, euphausiids, shrimps, amphipods) but also on small fish and various eggs and larvae (Ref. 1371). Caught mainly for reduction to fishmeal (Ref. 3383), trout pellets, fodder (Ref. 35388).

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

Oviparous, sexes are separate (Ref. 205). Migrates for spawning between the Shetland Islands and Norway and out of the Skagerrak. Major spawning grounds are Northwestern Scotland, Norway, Faeroe Islands and Iceland.

Estimates based on models

Preferred temperature (Ref. 115969): 5.9 - 10.1, mean 7.8 (based on 185 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00603 (0.00527 - 0.00689), b=3.06 (3.02 - 3.10), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.0 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.36; tm=2.3; tmax=5; Fec=27,000).

Prior r = 0.50, 95% CL = 0.33 - 0.75, Based on 3 full stock assessments.

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (41 of 100).

Price category (Ref. 80766): Low.
