Maximum Sustainable Yield for Discrete-time Population Dynamics
It is one of the important problems how to maximize the fish population catch permanently for our enough food supply. The amount for it is referred to as “Maximum Sustainable Yield (MSY) in fishery resource management. Originally the continuous-time logistic model has often been used to formulate and evaluate MSY. Although we can only deal with the case of globally asymptotically stable equilibrium as MSY by using this model, fish population usually shows the temporal fluctuation, so we should carefully consider the dynamics including unstable equilibria, exhibiting, for example, the periodic cycle and chaotic behavior. In this article we use discrete-time logistic model to evaluate the MSY other than asymtotically stable equibrium.
