5203 |a"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."
