INTRODUCTION OF SUITABLE STOCK-RECRUITMENT RELATIONSHIP BY A COMPARISON OF STATISTICAL-MODELS

A method for estimating the suitable stock-recruitment equations based on a comparison of various statistical models is presented. Fourteen statistical models including the Ricker curve and Beverton-Holt curve were considered. Stock-recruitment relations were estimated by the max imum likelihood method and suitable models were selected using AIC. Th irty-five sets of stock-recruitment data derived from published papers were analyzed. The results show that the various statistical models s elected as suitable models do not always coincide with the model used in the original papers. A detailed examination is needed to estimate t he stock-recruitment relationship.
