摘要

<正>In this paper,we establish the exploitation of continuous harvest of preda- tor 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 equilibria for proportional harvest. Finally,we solve the problem of optimal harvest policy using Pontragin's ma- ximal principle.
