Includes bibliographical references (page 4). "Landings have averaged 2000-3500 t over the past 11 years with the major effort coming from the Newfoundland otter trawlers in the southwest portion of Esquiman Channel in the wintertime and to a lesser extent the Danish seiners on the south side of St. Georges' Bay in the summertime. The age groups comprising this fishery have been reduced from 6-26 years old in 1976 to 6-15 years old in 1980 with this reduction in the number of age groups compensated by increased growth and recruitment. Despite the large reduction of the older age groups, over the past few years, biomass estimates and the number of age classes comprising the fishery appear to be stabilizing. This apparent stability has been generated by annual removals through fishing of about 3500 t"--Abstract. Includes abstract in French. gccst Fisheries gccst Surveys Canada.
