This article is concerned with optimal policies for a two-species agedependent population model with interaction of predator and prey,which is described by an integro-differential system and controlled by fertility.Necessary conditions for optimal control problems with free terminal states,infinite horizon and target sets are obtained,respectively,by means of Dubovitskii-Milyutin's functional approach.
