Remarks Often caught pelagically (Ref. 4705). Feeds on crustaceans (Ref. 4705, 6885), eelpouts, capelin, redfishes, deep sea prawns and other bottom invertebrates (Ref. 35388). Food also includes Atlantic cod, polar cod, young Greenland halibut, roundnose grenadier, barracudinas, sand lance and cephalopods (Ref. 5951). Greenland halibut <20 cm collected in the continental shelf <200 m deep, euphausiids were the important food. Fish >70 cm had a higher daily ration value (1.17% of body weight per day) than for two smaller size groups (0.66 and 0.64% of body weight per day for 30-49 and 50-69 size groups, respectively) (Ref. 55110). It is preyed upon by Greenland shark, white whales, narwhals, hooded seals, cod and salmon. Parasites of the species include 3 trematodes, Brachyphallus crenatus, Derogenes varicus and Fellidostomum furcigerum; and 1 nematode (Ref. 5951).

Association remarks Tagging experiments in Greenland waters between 1986 and 1998 to collect information on stock delineations, migration routes, and seasonal movements of fjord populations indicate that Greenland halibut migrate extensively between feeding and spawning areas and the seasonal pattern in the recovery of these fish indicates that Greenland halibut aggregate in the inner part of fjords during the second half of the year (when inshore waters are not covered with ice) (Ref. 94939). Are active swimmers and make extensive vertical migrations, spending less time at the bottom compared to other flatfishes. Larvae 27 mm and longer move vertically near the surface until they reach 70 mm, live at depths of about 250 m and drift with current; later they descend to greater depths (Ref. 86779).
