Basically solitary rather than a schooling fish. They exhibit a homing instinct (Ref. 9737). Adults inhabit rocky bottoms but may occur among floating seaweed. They migrate considerable distances in an annual cycle between deeper waters in winter and shallower waters in summer (Ref. 26141). Maximum depth reported at 868 m (Ref. 58426). Epibenthic-pelagic (Ref. 58426). Juveniles are found among algal clumps in bays and fjords moving offshore as they mature (Ref. 96431). During the spawning season the males become reddish in color on the underside, whereas females turn blue-green. Adults feed on ctenophores, medusas, small crustaceans, polychaetes, jelly fish and small fishes. Valued for their eggs, which make an inexpensive caviar (Ref. 9988). Eaten in Nordic countries, marketed fresh or smoked. Male flesh is most demanded and roe is sold fresh (Ref. 35388).
