| Summary: | Since 1988 Greenland Institute of Natural Resources has annually conducted a bottom trawl survey off West Greenland. The main purpose of the survey is to evaluate the biomass and abundance of Northern shrimp (Pandalus borealis), but data on fish species have been recorded regularly since 1992. This paper presents biomass and abundance estimates together with length frequencies of cod, Greenland halibut, redfish, wolffishes, American plaice and starry skate from the 1992-2005 surveys. Further, a recruitment index for Greenland halibut is presented. Materials and Methods The survey covers the offshore areas at West Greenland between 59°15'N and 72°30'N from the 3-mile limit to the 600 m depth contour line and the inshore area Disko Bay and Julianehåbs Bay (Fig. 1 and Table 1). The survey area is divided into NAFO Divisions, which were further subdivided into five depth strata (50-100, 101-150, 151-200, 201-400 and 401-600) on basis of depth contour lines. The area surveyed has, however, changed throughout the |
