Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 100 - 113; Spine anali: 0; Raggi anali molli: 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).
Body shape (shape guide): elongated; Cross section: oval.
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).
