Distribution and size of snow crab catches within and nearby the assessment area in 2003-2005 (left) and 2006- 2009 (right). Catches less than 100 kg are not shown. Greenland Halibut, Reinhardtius hippoglossoides During the period 2003-2009 annual catches of Greenland halibut in the Davis Strait were about 10,000-12,000 tonnes, but increased in 2010 to about 14,000 tonnes (Jørgensen 2010). Half of the catch ise from Greenland waters (Fig. 5.1.3) and constitutes a significant proportion of the total Greenlandic catch of Greenland halibut. The other half of the catch is taken in Canadian waters close to the Greenland border. In recent years most of the catches in Greenland waters use bottom trawl apart from a very small fishery which uses longlines (about 20 tonnes). The fishery has been distributed in the same way throughout the period (Fig. 5.1.3). Greenland halibut inshore exploitation: Greenland halibut in the inshore areas of West Greenland are considered to be recruited from the offshore stocks of Greenland halibut in the Davis Strait (Riget & Boje 1988). In northern Greenland (north of 67°N) a large inshore fishery with total catches up till 25,000 tonnes (Nygaard et al. 2010) will presumably be affected if the offshore stock collapses. In the assessment area inshore fishery is mainly conducted in Nuup Kangerlua (the Nuuk/Godthåb fjord) and catches peaked in the early 1980s at a level of more than 2,000 tonnes per year. The stock collapsed due to a high fishing mortality and there was no fishery in the fjord until 2009. In 2010 landings from Nuup Kangerlua were at a level of 230 tonnes. 55°W 55°W 50°W 50°W 68°N 66°N 64°N 62°N 151
