Abstract

Crustaceans, which are highly susceptible to the effects of climate change, are critical for food security worldwide. Yet, management rarely evaluates the performance of alternative regulatory strategies under climate-driven life history change. This limits the development of climate-ready management plans, undermining fisheries sustainability. We compared the performance of alternative minimum legal size (MLS) regulations under shifts in growth and maturity for American lobster in the Gulf of Maine, the most valuable single-species commercial fishery in the United States. Across the life history change scenarios examined, increasing MLS improved status indicators, while decreasing MLS eroded status indicators for spawning stock biomass, legal abundance, landings, and exploitation rate. Our results demonstrate that protecting the lobster stock by increasing MLS improves fishery output, highlighting that conservation and industry goals can be complementary. This study exemplifies the utility of MLS as a conservation measure for crustacean fisheries under climate change.

在气候驱动的生活史变化下，工业和保护目标对美国最有价值的渔业是相辅相成的

甲壳动物极易受到气候变化的影响，对全球粮食安全至关重要。然而，管理层很少评估气候驱动的生活史变化下替代监管策略的表现。这限制了气候管理计划的制定，破坏了渔业的可持续性。我们比较了缅因湾美国龙虾（美国最有价值的单一物种商业渔业）在生长和成熟度变化的情况下，替代最低法定规模（MLS）法规的表现。在研究的生命史变化情景中，增加MLS改善了产卵种群生物量、合法丰度、上岸量和开采率的状态指标，而减少MLS侵蚀了状态指标。我们的研究结果表明，通过增加MLS来保护龙虾种群可以提高渔业产量，这突出表明保护和行业目标可以互补。这项研究证明了MLS作为气候变化下甲壳类动物渔业保护措施的效用。

期刊介绍： Conservation Letters is a reputable scientific journal that is devoted to the publication of both empirical and theoretical research that has important implications for the conservation of biological diversity. The journal warmly invites submissions from various disciplines within the biological and social sciences, with a particular interest in interdisciplinary work. The primary aim is to advance both pragmatic conservation objectives and scientific knowledge. Manuscripts are subject to a rapid communication schedule, therefore they should address current and relevant topics. Research articles should effectively communicate the significance of their findings in relation to conservation policy and practice.
