Found on the continental shelf and slope to depths over 1,000 m (Ref. 27121). Juveniles (to about 64 cm) feed on small crustaceans and small deep-sea fishes such as lanternfishes, whereas larger individuals feed chiefly on small hakes and jack mackerel (Ref. 1371); cannibalism is common (Ref. 27121). Migrates southward in the spring and northward in autumn (Ref. 1371). Breeds throughout the year, peaks of reproductive activity in August and September (Ref. 36731). Marketed smoked, frozen, and fresh on ice; eaten steamed, fried and baked (Ref. 9988).
