The stage-structured predator-prey model and optimal harvesting policy. (English) Zbl 0961.92037

Summary: We establish a mathematical model of two species with stage structure and the relation of predator-prey, to obtain the necessary and sufficient condition for the permanence of two species and the extinction of one species or two species. We also obtain the optimal harvesting policy and the threshold of the harvesting for sustainable development.
