Abstract
In 1993, commercial inshore gillnet vessels continued exploratory fisheries for Greenland halibut in the north west Atlantic, off the coasts of Newfoundland and Labrador. Catch rates doubled those of fisheries conducted in 1992; five vessels fishing to maximum depths landed 518, 790 kg of Greenland halibut and 4,300 kg of roughhead grenadier. In the 1992 season fishing effort, fishing depths and fishing gear for 22 inshore gillnet vessels in the length range 16.5 to 19.5 m. were monitored in the north west Atlantic. Greenland halibut (Reinhardtius hippoglossoides) catches were analysed to identify catch rates, the average fish size, by-catch quantities and the mesh size versus size of fish caught. Recommendations included the expansion of deep-water gillnet fishing, detailed stock assessment studies, analysis of fishing pressure impact, and marketing and utilisation of the significant by-catch of roughhead grenadier.
