Climate change is altering the productivity of marine fisheries and challenging the effectiveness of historical fisheries management. Harvest control rules, which describe the process for determining catch limits in fisheries, represent one pathway for promoting climate resilience. In the USA, flexibility in how regional management councils specify harvest control rules has spawned diverse approaches for reducing catch limits to precautionarily buffer against scientific and management uncertainty, some of which may be more or less resilient to climate change. Here, we synthesize the control rules used to manage all 507 US federally managed fish stocks and stock complexes. We classified these rules into seven typologies: (1) catch-based; (2) constant catch; (3) constant escapement; (4) constant F; (5) stepped F; (6) ramped F and (7) both stepped and ramped F. We also recorded whether the control rules included a biomass limit (‘cut-off’) value or were environmentally linked as well as the type and size of the buffers used to protect against scientific and/or management uncertainty. Finally, we review the advantages and disadvantages of each typology for managing fisheries under climate change and provide seven recommendations for updating harvest control rules to improve the resilience of US federally managed fisheries to climate change.

美国联邦渔业管理中使用的收获控制规则及其对气候适应力的影响

气候变化正在改变海洋渔业的生产力并挑战历史渔业管理的有效性。捕捞控制规则描述了确定渔业捕捞限额的过程，代表了促进气候适应能力的一种途径。在美国，区域管理委员会在规定捕捞控制规则方面的灵活性催生了多种减少捕捞限制的方法，以预防性地缓冲科学和管理的不确定性，其中一些可能或多或少地适应气候变化。在这里，我们综合了用于管理所有 507 个美国联邦管理的鱼类种群和种群群的控制规则。我们将这些规则分为七种类型：（1）基于捕获；(2) 不断的捕捉；(3)恒速擒纵机构；(4)常数F；(5)阶梯式F；(6) 斜坡 F 和 (7) 阶梯式和斜坡 F。我们还记录了控制规则是否包括生物量限制（“截止”）值或是否与环境相关，以及用于控制的缓冲区的类型和大小防止科学和/或管理的不确定性。最后，我们回顾了每种类型学在气候变化下管理渔业的优缺点，并提供了七项更新收获控制规则的建议，以提高美国联邦管理的渔业对气候变化的适应能力。
