"The Greenland halibut (Reinhardtius hippoqlossoides Walbaum) is an amphiboreal, mesopelagic piscivorous predator. In Davis Strait, it is the object of an international fishery which uses bottom trawls, longlines, and gill nets. Young Greenland halibut inhabit nursery areas on the banks along both sides of the strait. As they approach sexual maturity, which they attain at about age 10-12, they seek deeper water. Mature females are larger than males. Greenland halibut spawn in spring primarily on the Continental slope and in deep basins (650-1000+ m). Currents distribute larvae along West Greenland and Baffin Island where they settle in the nursery grounds on the banks. In 1987, a winter fishery for this species began in Cumberland Sound (Baffin Island). Indigenous fishermen, operating from snow machines and sleds, set longlines through ice. They fish in depths between 600-1125 m. Their catch is predominantly female, aged 9-12. It is postulated that the fish in Cumberland Sound are a component of the larger population inhabiting Davis Strait"--Abstract, page iv. Includes abstracts in English and French.
