| Abstract: | A stage-structared fishery model with harvesting is proposed and analyzed in this paper. The existence of the equlibria of the model, along with their local stability, instability and global stability are discussed, respectively. Taxation threshod is obtained to sustain permanence and stability of the fishery resources. |
