Northeast Atlantic: southwest Barents Sea, sometimes at Bear Island, south to the English Channel, - and the Bay of Biscaye (Ref. 90172)-, around Iceland and Faeroe Islands.

Max length : 35.0 cm TL पुल्लिंग / अलिंग; (Ref. 1371); common length : 19.0 cm TL पुल्लिंग / अलिंग; (Ref. 4645); अधिकतम सूचित उम्र: 5 वर्षो (Ref. 273)
पृष्ठीय रीढ़ (सम्पूर्ण) : 0; गुदा कांटा: 0. Gray-brown dorsally, silvery on sides, white on belly. A dark blotch is at the upper edge of the pectoral-fin base.
Body shape (shape guide): fusiform / normal; Cross section: circular.
Benthopelagic to pelagic over muddy bottoms. Mostly found between 100 and 200 m. Feeds mostly on planktonic crustaceans (copepods, euphausiids, shrimps, amphipods) but also on small fish and various eggs and larvae (Ref. 1371). Caught mainly for reduction to fishmeal (Ref. 3383), trout pellets, fodder (Ref. 35388).
Oviparous, sexes are separate (Ref. 205). Migrates for spawning between the Shetland Islands and Norway and out of the Skagerrak. Major spawning grounds are Northwestern Scotland, Norway, Faeroe Islands and Iceland.
