Juveniles are pelagic, spending 2-3 years near the coast including rocky areas, kelp beds, sandy shores and estuaries . Juveniles may form schools with saithe (Pollachius virens) , and have also been found solitary and defending their feeding territory. Larger individuals move to the open sea and are often found around rocky areas at 40-100 m depth . Also observed around shipwrecks and oil platforms . Adults occur singly or in small dispersed shoals but is known to form dense shoals on spawning grounds . Suggested to undertake spawning migrations . Caught as bycatch in cod and saithe fisheries.
