Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 98-110; Anal spines: 0; Anal soft rays: 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.

IUCN Red List Status (Ref. 115185)

Endangered (EN) (A1d)

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 0.7500 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
4.0 ±0.5 se; Based on diet studies.

Resilience (Ref. 69278)
Very Low, minimum population doubling time more than 14 years (tmax=30; tm=10; K=0.02-0.2; Fec=1,300,000; also Musick et al. 2000 (Ref. 36717))

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

Price category (Ref. 80766)
