An assessment of the American plaice stock in NAFO subdivision 3Ps / by W. Brodie. : Fs70-8/87-46E-PDF

"Sampling data from 1973-81 were reviewed and recalculation of catch numbers and weights from this period, together with values from the more recent period permitted an assessment using sequential population analysis to be performed on this stock for the first time in several years. Calibration of the analysis with commercial CPUE indicated the fully-recruited fishing mortality in 1986 to be 0.18, slightly below the F0.1 level. Research vessel surveys in 1986 and 1987 indicate the biomass to be close to the average from 1980-87. Catch rates in the commercial fishery declined in 1986 from the very high levels observed in 1984 and 1985, but are still higher than the historical average. Catch projections, based on the sequential population analysis at Ft = 0.18, indicate the F0.1 catch in 1988 to be 5,100 tons"--Abstract, page 2.
