THE OPTIMAL HARVESTING OF A PREDATOR-PREY SYSTEM WITH STAGE-STRUCTURE

摘要：

In this paper, we establish the exploitation of continuous harvest of predator and prey with stage- structures. We investigate the properties of harvesting multispecies systems. With some special methods, we obtain boundedness and global attractiveness of all the nonnegative cquilibria for proportional harvest. Finally, we solve the problem of optimal harvest policy using Pontragins maximal principle.
