Assessment of Pollock in Division 4VWX and Subarea 5

Pages : 28
Book Description
Research. vessel survey results are inconclusive for pollock, however commercial catch rates would indicate that the 1979 year-class is strong whilst the 1978 year-class is not as large as previously thought. Cohort analyses further suggest that fishing mortality has been underestimated in past assessments, such that year-classes preceding 1979 have been exploited to a greater extent. A terminal F of 0.35 was considered the most appropriate level to provide the best estimate of stock status in 1981. Projections with F0 1 catches in 1982 and 1983 gave 42,000 and 48,000 mt respectively. If the TAC is taken in 1982 (54,000 mt) then the projected catch for 1983 is 45,000 mt.

Stock Status of Pollock in NAFO Division 4VWX and Subarea 5

Languages : en
Pages : 33
Book Description
"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.
