Abstract

The recent trend in the study of dynamics of fish stocks consists in building up suitable simple mathematical models which adequately describe the dynamics of fish stocks. One method is to assume some simple growth law such as logistic law for the fish stock as a whole. This method may be termed a synthetic approach and has recently been developed a great deal by Schaefer. 'The analytic method developed by Beverton and Holt (1957) and others assumes that changes in fish stocks result due to simultaneous operation of vital rates such as, recruitment, growth, natural and fishing mortality rates. Under very simple assumptions, a simple theoretical model is constructed which contains these vital rates as parameters.
