Greenland Halibut, Reinhardtius hipp<strong>og</strong>lossoides<br />
During the period 2003-2009 annual catches of Greenland halibut in the <strong>Davis</strong><br />
<strong>Strait</strong> were about 10,000-12,000 tonnes, but increased in 2010 to about<br />
14,000 tonnes (Jørgensen 2010). Half of the catch ise from Greenland waters<br />
(Fig. 5.1.3) and constitutes a significant proportion of the total Greenlandic<br />
catch of Greenland halibut. <strong>The</strong> other half of the catch is taken in Canadian<br />
waters close to the Greenland border. In recent years most of the catches in<br />
Greenland waters use bottom trawl apart from a very small fishery which<br />
uses longlines (about 20 tonnes). <strong>The</strong> fishery has been distributed in the<br />
same way throughout the period (Fig. 5.1.3).<br />
Greenland halibut inshore exploitation: Greenland halibut in the inshore areas<br />
of West Greenland are considered to be recruited from the offshore stocks of<br />
Greenland halibut in the <strong>Davis</strong> <strong>Strait</strong> (Riget & Boje 1988). In northern Greenland<br />
(north of 67°N) a large inshore fishery with total catches up till 25,000<br />
tonnes (Nygaard et al. 2010) will presumably be affected if the offshore stock<br />
collapses. In the assessment area inshore fishery is mainly conducted in<br />
Nuup Kangerlua (the Nuuk/Godthåb fjord) and catches peaked in the early<br />
1980s at a level of more than 2,000 tonnes per year. <strong>The</strong> stock collapsed due<br />
to a high fishing mortality and there was no fishery in the fjord until 2009. In<br />
2010 landings from Nuup Kangerlua were at a level of 230 tonnes.<br />
