Further work on nonparametric prediction of recruitment of 2J3KL cod from stock and environmental influences / by J.C. Rice. : Fs70-8/87-54E-PDF
"Nonparametric methods for projecting expected recruitments from stock and environmental influences were used to estimate expected recruitments for the 2J+3JK cod stock. For the recruitments observed between 1962 and 1980, stock size accounted for 62% of the variance in recruitment. Spring and summer surface temperatures accounted for 6.5% of the residual variance in recruitment; winter temperatures and salinities accounted for 7.1% of the residual variance. Using these results, the 1981 year-class is predicted to be about 300 million recruits (numbers at age 4), the 1982 year-class is predicted to be slightly smaller (280 million recruits), the 1983 and 1984 year-classes between 350 and 400 million recruits, and the 1985 year-class substantially smaller; perhaps 200 million recruits"--Abstract, page 2.
