Ecología
marino bentopelágico; oceanodromo (Ref. 51243); rango de profundidad 50 - 300 m (Ref. 54932), usually 100 - 200 m (Ref. 54932). Temperate; 79°N - 48°N, 27°W - 30°E (Ref. 54932)
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.
Length at first maturity / Tamaño / Peso / Age
Maturity: Lm 14.0, range 11 - 15 cm
Max length : 35.0 cm TL macho / no sexado; (Ref. 1371); common length : 19.0 cm TL macho / no sexado; (Ref. 4645); edad máxima reportada: 5 años (Ref. 273)
Espinas dorsales (total) : 0; Espinas anales: 0. Gray-brown dorsally, silvery on sides, white on belly. A dark blotch is at the upper edge of the pectoral-fin base.
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.
