Environment / Climate / Range
Marine; benthopelagic; oceanodromous (Ref. 51243); depth range 50 - 300 m (Ref. 54932), usually 100 - 200 m (Ref. 54932). Temperate; 79°N - 48°N, 27°W - 30°E (Ref. 54932)
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 11 - 15 cm
Max length : 35.0 cm TL male/unsexed; (Ref. 1371); common length : 19.0 cm TL male/unsexed; (Ref. 4645); max. reported age: 5 years (Ref. 273)
spines: 0. Gray-brown dorsally, silvery on sides, white on belly. A dark blotch is at the upper edge of the pectoral-fin base.
Northeast Atlantic: southwest Barents Sea, sometimes at Bear Island, south to the English Channel, around Iceland, and at the Faeroe Islands.
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).
