提出了具有阶段结构的单一物种渔业的动态模型，使用税收作为控制工具来保护鱼类种群免遭过度捕捞。推导了系统的局部稳定性和全局稳定性的标准。最优税收政策是利用庞特里亚金极大原则建立的。数值模拟表明，增加税收可以保护渔业资源。
A dynamic model for a single species fishery with stage structure is proposed using taxation as a control instrument to protect the fish population from overexploitation. Criteria for local stability and global stability of the system are derived. The optimal tax policy is established by using Pontryagin's maximal principle. By numerical simulation, it is shown that the fishery resources can be protected by increasing the tax.
