Status of the cod stock in Subdivision 3Ps / by C.A. Bishop and S. Gavaris. : Fs70-8/82-33E-PDF
"Cod catches from Subdivision 3Ps have increased since the low of 26,000 t in 1978 and have constantly been above the recommended TAC. The catch in 1981 which was mainly by inshore gears was dominated by the 1974 and 1975 year-classes. Using catch rate data and cohort analyses, the terminal fishing mortality in 1981 was estimated at 0.40. A non-equilibrium surplus production analysis suggested past overexploitation as well as a recent trend in stock improvement. The predicted non-equilibrium yield in 1982 at 2/3 effort MSY was 35,000 t."
