Status of the cod stock in subdivision 3Ps / by C.A. Bishop. : Fs70-8/80-48E-PDF

"Catches declined in the 1970's to a low of approximately 26,000 t in 1978. Catch at age data from the commercial fishery in 1979 indicate that the 1974 year-class made up 50% of the catch. Survey data show that the 1978 year-class is strong. From a series of cohort runs an appropriate terminal F in 1979 was determined using the relationship of cohort biomass with standard C.P.U.E. Using this cohort biomass at age and an estimate of recruitment, the projected catch in 1981 fishing at F0.1 would be approximately 32,700 t"--Abstract, page [1].
