Found usually between 70 and 370 m depth. Adults live close to the bottom during day-time, but move off-bottom at night. Adults feed mainly on fish (small hakes, anchovies, pilchard, herrings, cod fishes, sardines and gadoid species) and squids. The young feed on crustaceans (especially euphausiids and amphipods). Are batch spawners (Ref. 51846). Almost entirely marketed fresh, whole or filleted, to specialized restaurants or retail markets (Ref. 58452). Utilized fresh, dried or salted and frozen; can be steamed, fried, microwaved and baked (Ref. 9988). Stocks seem to be over-fished (Ref. 35388).
Continuous recruitment of oocytes connotes indeterminate fecundity for this species (Ref. 79799).
