Assessment of the 4VsW cod stock complex / by J.J. Maguire.: Fs70-8/81-19E-PDF
"Research vessel survey population estimates and Canadian tonnage class 5 average catch per unit of effort during the months of January to April were used to fine tune ages 5 and older VPA mean numbers and biomass. A fully recruited 1980 fishing mortality of F = 0.225 was considered to best represent the age 5 and older stock status. Year-class size at ages 4 and 3 in 1980 were adjusted by regression with an index of year-class size from R.V. surveys while year-class size at age 2 was estimated from a relationship between year-class size at age 1 and the age 7 and older biomass during the year of spawning. The 1982 F0.1 catch is estimated to be 53,700 mt."--Abstract.
