Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 93-103; Anal soft rays : 62 - 75; Vertebrae : 64 - 67. Barbel on present on chin, none on snout, its length equal to eye diameter. Color is variable; dorsally dark red-brown or green brown to yellow shading into pale color on belly. Young specimens may have six transverse yellow bands on sides. Vertical fins with dark margin rimmed with white.

Biology     Glossary (e.g. epibenthic)

Found in small shoals on rough, rock, gravel, or pebble bottoms. Generally keeps far from the shore, near the bottom, mostly between 150 and 450 m in the northeastern Atlantic, and between 18 and 550 m in the northwestern Atlantic. Occurs at a temperature range of 0°-10° C (Ref. 9988 ). Solitary or in small groups. Feeds on crustaceans and shellfishes, benthic fishes (flatfishes and gurnard) and even on starfishes. Preyed upon by seals (Ref. 9988 ). Sold fresh, frozen as fillets or dried salted. Eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Spawns in shallower waters between 40-400 m, usually 100 to 200 m. Most important spawning grounds are located between Scotland and Iceland, from 200 to 500 m depth. In the Gulf of Maine, spawning grounds can be found in shallower waters (>50 m). Some individuals even spawn close inshore in Cape Cod, Provincetown Harbor and the Isles of Shoals (Ref. 1371 ).

Estimates based on models

Preferred temperature (Ref. 115969 ): 0.5 - 7.7, mean 3.6 (based on 726 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00708 (0.00439 - 0.01142), b=3.09 (2.95 - 3.23), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.9   ±0.3 se; Based on diet studies. Generation time: 8.1 (5.8 - 11.1) years. Estimated as median LN(3)/K based on 11 growth studies. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.08-0.16; tm=8-10; tmax=20; Fec=2 million). Prior r = 0.45, 95% CL = 0.30 - 0.68, Based on 7 stock assessments. Vulnerability (Ref. 59153 ):  High vulnerability (63 of 100) . Price category (Ref. 80766 ):   Low .
