Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 1; Mjukstrålar i ryggfenan (totalt) : 100 - 113; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 83 - 90. Dorsal part of body purplish blue, belly silvery with a slight bluish tinge; small melanophores scattered on fin membrane of dorsal and anal fins; inside of mouth blackish (Ref. 1371).
Schooling species which are concentrated on the outer part of the continental shelf (Ref. 1371). Feeds mainly on fish (herring, anchovies, lantern fishes), also on mysids, cephalopods, euphausiids and amphipods (Ref. 1371). Migrates southward in spring and summer and northward in winter (Ref. 1371). Utilized fresh, frozen and for fishmeal (Ref. 1371).
