📖 Overview

Basically solitary rather than a schooling fish. They exhibit a homing instinct . 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 . Maximum depth reported at 868 m . Epibenthic-pelagic . Juveniles are found among algal clumps in bays and fjords moving offshore as they mature . 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 . Eaten in Nordic countries, marketed fresh or smoked. Male flesh is most demanded and roe is sold fresh .
