Life Cycle
provided by Fishbase
Gonads of male and female do not mature at the same time. The spermatozoa are kept in the ovary of the female after copulation until such time that the eggs ripen paving the way for fertilisation (Ref. 74488). Gives birth to 50,000-350,000 pelagic larvae of 8 mm length (Ref. 35388).
Migration
provided by Fishbase
Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.
Trophic Strategy
provided by Fishbase
Epibenthic-pelagic. Feeds on crustaceans and fishes (Ref. 58426). Also feeds on planktonic organisms (Ref. 12223). Preyed upon by Atlantic halibut, Atlantic cod, swordfish and harbor seals. Parasites of the species include 6 trematodes, 1 cestode, 6 nematodes and 3 copepods (Ref. 5951).
Biology
provided by Fishbase
Found off the coast from 100-1000 m; juveniles found in fjords, bays and inshore waters. Normally trawled in deep water (Ref. 9988). Benthic (Ref. 5951). Feed mostly on euphausiids in summer; herrings in autumn and winter; capelins, herrings, euphausiids and ctenophores in spring. Gregarious throughout life. A slow growing species (Ref. 9988). Ovoviviparous, gonads of male and female do not mature at the same time. The spermatozoa are kept in the ovary of the female after copulation until such time that the eggs ripen paving the way for fertilization (Ref. 74488). Copulation takes place in late summer or early autumn (Ref. 35388, 34817); in winter females give birth to 50,000-350,000 pelagic larvae of 8 mm length (Ref. 35388). Utilized fresh and frozen; eaten fried, broiled, microwaved and baked (Ref. 9988).
