| Abstract: | The article deals with single-species growth model of stage-structure and diffusion , With mature population harvesting,we obtain the conditions for existence of a globally asmptotically stable positive equilibrium , consider the optimal harvesting policy. Further, we consider the effects of diffusion on the total population size . |

| Keywords: | Stage structure Stability equilibrium Optimal harvesting Diffusion |
