Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

North Atlantic: from about 37°N to Baffin Island and Greenland in the western Atlantic, and off Iceland and Norway south to North Africa in the eastern Atlantic. Reported to occur from the tongue of the Ocean east of Andros Islands (about 24°N, 77°W) in the Bahamas.

Biology     Glossary (e.g. 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).
