Remarks Non-schooling (Ref. 28073). Lives close to the coast and is rarely found offshore, in deeper water (Ref. 1371). Benthic (Ref. 58426). Feeds on fishes, shrimps, crabs, euphausiids, squids, polychaetes, and echinoderms. There is probably competition between this species and Gadus morhua (Ref. 1371). Parasites of the species include sealworm (Phocanema decipiens) in flesh, copepod (Lernaeocera branchialis) on gills and cestode (Pyramicocephalus phocarum) in the intestine (Ref. 5951).
