Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 98 - 110; Spine anali: 0; Raggi anali molli: 73 - 85. Uniformly dark brown or black; young marbled or spotted with paler marks (Ref. 4705).

Adults are benthic but occasionally pelagic (Ref. 4705). Feed mainly on other fishes (cod, haddock, pogge, sand-eels, herring, capelin), but also takes cephalopods, large crustaceans and other bottom-living animals. Batch spawner (Ref. 51846). Growth rate varies according to density, competition and availability of food. Slow growth rate and late onset of sexual maturity, halibut populations can be seriously affected by overfishing (Ref. 35388). Utilized fresh, dried or salted, smoked and frozen; can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Also Ref. 58426.

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Males reach sexual maturity at 7-8 years and females at 10-11 years. Spawning happens from December to April, near the bottom (300 to 700 m), at temperatures between 5 and 7°. Egg size 3.0-3.8, larval size at hatching 6.5 mm (Ref. 4705).

Estimates based on models

Preferred temperature (Ref. 115969): 0.4 - 7.9, mean 3.4 (based on 1760 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00398 - 0.00759), b=3.17 (3.08 - 3.26), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.5 se; based on diet studies.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (tmax=30; tm=10; K=0.02-0.2; Fec=1,300,000; also Musick et al. 2000 (Ref. 36717)).

Prior r = 0.27, 95% CL = 0.18 - 0.40, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (88 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (43 of 100).

Price category (Ref. 80766): Very high.
