Offshore species which inhabit the outer part of the continental shelf and upper part of the slope. Feed at night when they come up towards the surface (Ref. 1371). Juveniles feed primarily on crustaceans (Ref. 58452). Adults' food consists primarily of fishes (particularly lantern fishes, sardines and anchovies) and, to a lesser extent, crustaceans and squids (Ref. 1371). Spawning occurs near the bottom at 330-550 m depth range from April to July in New England and from late spring to early autumn in the Gulf of Mexico and the Carribean Sea (Ref. 58452). Marketed fresh, frozen and smoked.
