Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Invades shelf waters during summer and concentrating over the continental slope in winter. Forms schools (Ref. 9072). The young feed on euphausiids and amphipods and occasionally on copepods, cephalopods and small fish. Utilized in frozen blocks and as fishmeal. In Japan used as suerii (minced meat) for karaoke (fish cake) (Ref. 27363). Can be fried, microwaved and baked (Ref. 9988).
