Fisheries Instrument Choice under Uncertainty
利用实际渔业数据构建动态模型,比较不确定性下总捕捞量控制和总努力量控制两种管理方式对预期利润、方差、最优种群规模等的影响,为渔业管理提供工具选择依据。
This paper uses data from an actual fishery to construct a tractable, dynamic model to compare expected profit and its variance, optimal stock size, optimal harvest rate, and optimal fishing effort under different management regimes under uncertainty. The results provide a comparison of instrument choice between a total harvest control and a total effort control under uncertainty, an original method to evaluate the tradeoffs between profits and other criteria in a dynamic context, and insights regarding the relative merits of catch and effort controls in fisheries management. <i></i>
