Abstract:A class of two species and predator-prey model with a stage-structure is considered.The existence and the unique of the positive equilibrium are discussed.Some conditions for global asymptotic stability of the unique positive equilibrium are obtained.The optimal harvesting strategy is gained by applying the optimal control theory.
Keywords:predator-prey  stage-structure  globally asymptotical stability  optimal harvesting
