在世界许多地区，休闲渔业并未得到可持续管理。这可能与渔业管理模型中钓鱼者行为和钓鱼者异质性的遗漏或过度简化有关。我们提出了一种综合生物经济建模方法，以研究有关钓鱼者行为、钓鱼者偏好和钓鱼者群体组成的不同假设如何改变对最佳休闲渔业管理的预测，其中最佳法规是通过最大化钓鱼者的总效用来确定的。我们报告了典型的白斑狗鱼（Esox lucius）渔业的四项主要结果。首先，考虑到动态钓鱼者的行为改变了对最佳钓鱼规则的预测。其次，不同钓鱼者类型之间的最佳输入和输出调节差异很大。第三，钓鱼者群体的构成（就钓鱼者类型而言）对于确定最佳法规很重要。第四，用于量化总体使用的福利措施...
In many areas of the world, recreational fisheries are not managed sustainably. This might be related to the omission or oversimplification of angler behaviour and angler heterogeneity in fisheries-management models. We present an integrated bioeconomic modelling approach to examine how differing assumptions about angler behaviour, angler preferences, and composition of the angler population altered predictions about optimal recreational-fisheries management, where optimal regulations were determined by maximizing aggregated angler utility. We report four main results derived for a prototypical northern pike (Esox lucius) fishery. First, accounting for dynamic angler behaviour changed predictions about optimal angling regulations. Second, optimal input and output regulations varied substantially among different angler types. Third, the composition of the angler population in terms of angler types was important for determining optimal regulations. Fourth, the welfare measure used to quantify aggregated uti...
