Highly variable recruitment and a complex harvest strategy resulted in dramatic inter-annual changes in historical catches, including prolonged closure periods, for Bering Sea Tanner crab (Chionoecetes bairdi). Current management regulations, linked to recent frequent closures, led to an industry-initiated cooperative effort to reevaluate the harvest control rule (HCR) that forms part of the State of Alaska harvest strategy. Management strategy evaluation (MSE) was used to assess conservation and economic trade-offs of fifteen HCR options that differed in how females were considered. Several male-only HCRs performed similarly to those that accounted for females. However, the inclusion of both sexes reflected conservation and economic objectives while acknowledging the uncertainty around reproductive dynamics. The HCR selected by the Alaska Board of Fisheries included a threshold for opening the fishery based on mature male biomass (MMB), scalars based on relative levels of mature female biomass (MFB) and MMB that determine the exploitation rate on MMB, and a maximum exploitation cap on industry-preferred sizes of legal males. This work illustrates how manager-stakeholder collaboration may enable improved fishery management. Our analysis provided managers with a tool to facilitate productive and transparent dialogue with industry, with the goal of accounting for conservation and economic objectives, given some of the underlying biological uncertainty associated with reproductive dynamics. This study demonstrates that the inclusion of reproductive buffers in HCRs for male-only fisheries may be able to better achieve conservation goals without sacrificing economic performance.

高度可变的招募和复杂的捕捞策略导致了历史捕获量的显着年际变化，包括延长的封闭期，白令海坦纳蟹 ( Chionoecetes bairdi）。与最近频繁关闭相关的现行管理法规导致了行业发起的合作努力，以重新评估构成阿拉斯加州收获战略一部分的收获控制规则 (HCR)。管理策略评估 (MSE) 用于评估 15 种 HCR 选项的保护和经济权衡，这些选项在如何考虑女性方面有所不同。几个仅限男性的 HCR 的表现与那些占女性的 HCR 相似。然而，包括两性反映了保护和经济目标，同时承认生殖动态的不确定性。阿拉斯加渔业委员会选择的 HCR 包括一个基于成熟雄性生物量 (MMB) 的渔业开放阈值、基于成熟雌性生物量 (MFB) 和 MMB 相对水平的标量，它们决定了 MMB 的开发率，以及行业首选的合法男性规模的最大剥削上限。这项工作说明了管理者与利益相关者的合作如何能够改善渔业管理。我们的分析为管理人员提供了一种工具，以促进与行业的富有成效和透明的对话，目标是考虑到保护和经济目标，考虑到与生殖动态相关的一些潜在生物不确定性。这项研究表明，在仅雄性渔业的 HCR 中包含繁殖缓冲区可能能够在不牺牲经济绩效的情况下更好地实现保护目标。我们的分析为管理人员提供了一种工具，以促进与行业的富有成效和透明的对话，目标是考虑到保护和经济目标，考虑到与生殖动态相关的一些潜在生物不确定性。这项研究表明，在仅雄性渔业的 HCR 中包含繁殖缓冲区可能能够在不牺牲经济绩效的情况下更好地实现保护目标。我们的分析为管理人员提供了一种工具，以促进与行业的富有成效和透明的对话，目标是考虑到保护和经济目标，考虑到与生殖动态相关的一些潜在生物不确定性。这项研究表明，在仅雄性渔业的 HCR 中包含繁殖缓冲区可能能够在不牺牲经济绩效的情况下更好地实现保护目标。
