An Open-Access Analysis of the Northern Anchovy Fishery
利用美国减少渔业数据估计生长和产量函数，建立开放获取模型分析北方鳀鱼渔业的长期均衡和极限周期，并扩展模型纳入墨西哥和美国渔业行为，预测未来动态。
In this paper we model the northern anchovy fishery using open access dynamics. The growth and production functions are estimated from U.S. reduction fishery data and we explore the dynamics of a simple open access model using these estimates. The existence of a stable long-term equilibrium and limit cycles are demonstrated. An expanded model then incorporates the behavior of the Mexican and U.S. fisheries into the open-access framework. Nonlinear optimization is used to estimate cost and adjustment coefficients for both fleets. We apply this model to forecast the likely future behavior of the northern anchovy fishery.
