Biology     Glossary (e.g. epibenthic)

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).
