Abstract: In the paper we tend to investigate the harvesting effort of prey species in prey predator model with a strong Prey ( N1 ),and a weak Predators ( N2 ). The system is delineated by a system of ordinary differential equations. The Four equilibrium points are known. Local stability analysis is mentioned at every equilibrium points. Global stability is studied by constructing appropriate Lyapunov’s function. Additional Numerical simulation is performed and known the parameters for the system that becomes stable and unstable. Further the results are compared with harvesting effort and while not effort on the prey species. The Harvesting efforts of the prey species with catch ability constant and effort are known that unstable system becomes stable therefore the harvesting effort stabilizes the system.
