Management strategies for commercial marine species in Northern ecosystems. Proceedings of the 10th Norwegian-Russian Symposium. Bergen, 27-29 August 2003. Greenland halibut (Reinhardtius hippoglossoides (Walbaum)) are widely distributed over wide geographic areas of the Northeast Atlantic Ocean, with no break in the continuity of the distribution from the arctic Frans Josef Land and Novaya Zemlya archipelagos in the north and east to beyond the boreal Shetland Islands in the south. Although the entire Greenland halibut resource in the North Atlantic is genetically homogeneous, they comprise a single interbreeding stock in the Barents Sea and Norwegian Sea areas, which is known as the Northeast Arctic stock. In general, and for most of the year, larger fish become more abundant and smaller fish less abundant in progressively deeper water with peak abundance occurring over a depth range of 400-1 000 m. But during the spring and summer, the mature and bigger fish may be shallower.
