了解休闲垂钓的努力如何应对监管调整是重要的重建过度捕捞的股票，如大西洋条纹鲈鱼。在本文中，我们使用所述的偏好选择实验数据来评估个人垂钓者的参与可能会对钓鱼行程特征的变化做出反应，特别是小型，中型和奖杯条纹鲈鱼的数量保持和释放。我们用这些结果来模拟替代捕鱼政策在马萨诸塞州，罗得岛，康涅狄格州的垂钓者福利，垂钓者的努力，休闲捕鱼死亡率和女性产卵种群生物量（SSB）的综合效果。我们发现，广泛的经济有效的政策是可用的，如果主要管理目标是控制休闲捕鱼死亡率。相比之下，我们发现，有效的政策范围是相当狭窄的，如果主要的管理目标是保护女性SSB。此外，在分析的36项替代政策中，只有一项政策; 28“至36”的一条鱼收获槽，预计相对于2015年的一条鱼，28“或更长的实际政策，在总产卵量和雌性产卵量方面都将实现不小的减少。实施一个鱼收获槽28“至36”来与最小的成本方面放弃垂钓者的福利，由于相对较低的利率，其中奖杯条纹低音超过36“遇到。
Understanding how recreational angling effort responds to regulatory adjustment is important for rebuilding overfished stocks such as Atlantic striped bass Morone saxatilis. In this paper, we use stated preference choice experiment data to evaluate how individual angler participation may respond to changes in fishing trip characteristics, particularly the number of small, medium-sized, and trophy striped bass kept and released. We use these results to simulate the aggregate effect of alternative fishing policies in Massachusetts, Rhode Island, and Connecticut on angler welfare, angler effort, recreational fishing mortality, and female spawning stock biomass (SSB). We find that a wide range of economically efficient policies are available if the primary management objective is to control recreational fishing mortality. In contrast, we find that the range of efficient policies is quite narrow if the primary management objective is to protect female SSB. Additionally, only one of the 36 alternative policies analyzed; a one-fish harvest slot of 28″ to 36″, is expected to achieve a non-trivial reduction in both total and female spawning stock removals relative to the actual 2015 policy of one fish, 28″ or longer. Implementing a one-fish harvest slot of 28″ to 36″ comes with minimal costs in terms of foregone angler welfare due to the relatively low rate at which trophy striped bass in excess of 36″ are encountered.
