| 520 | 3 |a"Reported landings, catch at age and research indices for Canada and the USA are presented for the 5Zj,m management unit. Reported landings in 1989 decreased from 20000 t in 1988 to about 14000 t, primarily due to a reduction in Canadian OTB landings. Canada accounts for about 65% of total landings. Landings were dominated by the 1985 (40%) and the 1987 (27%) yearclasses in 1989. Revised estimated of USA survey indices (spring and autumn) in the 5Zj,m were calculated. Catch at age and all three survey indices were used in an ADAPT formulation to estimate population status. The resultant estimate of 3+F in 1989 was 0.29, the lowest in the series and may reflect premature closure of the Canadian OTB fishery. Population biomass in 1990 is estimated to be 69000 t, well above the 49000 t average. Catch projection for 1991, assuming a 1990 catch of 22000 t, indicates catches in the order of 11000 t (F0.1), 16000 t (F 50%) and 22000 t (status quo). Fishing mortality (3+) in 1990 is expected to be 0.39 and between 0.2 - 0.4 in 1991, depending on catch options. An analysis of the ratio of biomass in the Canadian zone of 5Zj,m indicates considerable seasonal and annual variation but an overall average of about 70%"--Abstract, page 1. |
