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 short-lived organisms such as penaeid shrimps.

This volume documents the usefulness of multivariate methods û notably multiple regression, path analysis and canonical correlation û in the context of aquaculture, which has to date tended to neglect such methods, and hence to underutilize available data. All examples used here stem from...
