Abstract

A dynamical predator-prey model with constant prey harvesting, proportional harvesting in predator has been studied. The square root functional response also has been incorporated in the system to describe the prey herd behavior, assuming the average handling time is zero. The existence and the local stability of equilibria of the system have been discussed. It is examined that, two types of bifurcation occur in the system. The two types of bifurcations have been analyzed, and it has been found by analyzing the saddle-node bifurcation that, there is a maximum sustainable yield . At >(1/4) , the prey population will abolish from the system and then extinction of the predator population will happen. But if 0
