Biologia     Glossário (p.ex. 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).

Ciclo de vida ou comportamento de acasalamento Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

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).
