"Research vessel surveys and commercial catch rates indicate a slight decline in total stock biomass from a maximum in 1980. There has been a trend of decreasing size at age in recent years. Consequently although the 1981 quota was undercaught, F0,1 was achieved. It was difficult to discriminate among a wide range of 1981 terminal fishing mortalities using conventional relationships. A terminal F of 0.35 was considered most appropriate for projection of catches. F0 . 1 catches in 1982 and 1983 were 18,500 and 20,000 mt respectively. If the TAC is taken in 1982 (23,000 mt.) the projected catch for 1983 is 19,000 mt." Includes abstract in French. gccst Fisheries gccst Salt water fish Canada. Department of Fisheries and Oceans.
