Under climate change, shifts in distributions of commercialized marine species challenge livelihoods and management in some fisheries and create opportunities in others. Whether existing management processes can enable fishers to access emergent fisheries – efforts by fishers to commercialize species – is unclear. Thus far, the literature has largely focused on reactive management processes that lead to overharvest and conflicts over fisheries allocations under species distributional shifts. We examine the progress and outcomes of 144 emergent fisheries in the state waters of Alaska, illustrating the historical diversity of management mechanisms, regions, species, and gears in the state's unique system of permitting and data collection for emergent fisheries. We further examine 28 emergent fisheries' roles in fishing portfolios through a métier analysis, finding that most are small extensions to existing portfolio strategies instead of novel opportunities for specialization. Together, these findings underscore challenges in adapting current processes to future shifts in marine species distributions, reflecting the need for large scale reconsiderations of scale, tradeoffs and a more holistic approach.

在气候变化下，商业化海洋物种分布的变化对一些渔业的生计和管理提出了挑战，但也为其他渔业创造了机会。现有的管理流程是否能够使渔民获得新兴渔业（渔民将物种商业化的努力）尚不清楚。迄今为止，文献主要集中于在物种分布变化下导致过度捕捞和渔业分配冲突的反应性管理过程。我们研究了阿拉斯加州立水域 144 个新兴渔业的进展和成果，说明了该州独特的新兴渔业许可和数据收集系统中管理机制、区域、物种和渔具的历史多样性。我们通过专业分析进一步研究了 28 个新兴渔业在渔业组合中的作用，发现大多数都是对现有组合策略的小规模扩展，而不是专业化的新机会。总之，这些发现强调了使当前进程适应未来海洋物种分布变化的挑战，反映出需要大规模重新考虑规模、权衡和更全面的方法。
