Stock status of pollock in NAFO division 4VWX and subarea 5 / by J.M. McGlade, M.C. Annand, and D. Beanlands. : Fs70-8/83-34E-PDF
"Commercial and research vessel survey catch rates for all ages were similar to those in 1981, however, research catch rates at age for fish of ages 3-5 were very different. Overall landings dropped from approximately 58,000 t to 55,000t. In a series of SPAs, it was possible to discriminate amongst terminal fishing mortalities for 1982, by using commercial catch rates. Total stock biomass showed a slight decrease in 1982 compared to 1980-1981. A terminal F of 0.3 was considered most appropriate for the projection of catches. F0.1 catches in 1983 and 1984 were 52,500 t and 53,000 t respectively. If the TAC is taken in 1983 (45,000 t) the projected catch for 1984 is 55,000 t"--Abstract.
