Estimation of yield per recruit when growth and fishing mortality oscillate seasonally
Type: Journal Article
A general form of the yield equation is presented. This is used to investigate the effects of seasonal growth oscillations on estimation of yield per recruit. The results show that these effects will be strongest in ...
