Short description Morfología | Morfometría

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.

Biología     Glosario (por ej. epibenthic)

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).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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.
