Biologie     Glossaire (ex. epibenthic)

Benthopelagic to bathypelagic in about 400 and 1200 m depth. Minimum depth from Ref. 1371. Form large schools at 600 to 900 m depth (Ref. 9988). Feed on a variety of fish and invertebrates, but primarily on pelagic crustaceans such as shrimps, amphipods and cumaceans; cephalopods and lantern fishes constitute a lesser portion of the diet. Batch spawner (Ref. 51846). This species is currently facing overexploitation in the North Atlantic. Utilized frozen and for fishmeal; can be fried and baked (Ref. 9988).
