A Conceptional Analysis of Dynamics and Production in Bioeconomic Models
对年龄结构生物经济模型中的捕捞函数和种群动态方程进行了推广，以纳入密度依赖性，并分析了从均匀分布到集群鱼类的脉冲捕捞经济收益变化，对渔业管理有重要启示。
Harvesting functions and stock dynamic equations in age‐structured bioeconomic models are generalized in order to incorporate density dependence. Using this generalization, anything from completely uniformly distributed fish to extreme schooling can be analyzed. The classical Beverton–Holt model comes out as a special case of the generalized model. The generalization can be applied both for simulation as well as for optimization purposes given appropriate software. Conceptual analysis indicates that pulse fishing seems to become less and less economically profitable as we move from uniformly distributed fish to schooling species. This has important implications for how fish stocks ought to be managed.
