Marine biota are redistributing at a rapid pace in response to climate change and shifting seascapes. While changes in fish populations and community structure threaten the sustainability of fisheries, our capacity to adapt by tracking and projecting marine species remains a challenge due to data discontinuities in biological observations, lack of data availability, and mismatch between data and real species distributions. To assess the extent of this challenge, we review the global status and accessibility of ongoing scientific bottom trawl surveys. In total, we gathered metadata for 283,925 samples from 95 surveys conducted regularly from 2001 to 2019. We identified that 59% of the metadata collected are not publicly available, highlighting that the availability of data is the most important challenge to assess species redistributions under global climate change. Given that the primary purpose of surveys is to provide independent data to inform stock assessment of commercially important populations, we further highlight that single surveys do not cover the full range of the main commercial demersal fish species. An average of 18 surveys is needed to cover at least 50% of species ranges, demonstrating the importance of combining multiple surveys to evaluate species range shifts. We assess the potential for combining surveys to track transboundary species redistributions and show that differences in sampling schemes and inconsistency in sampling can be overcome with spatio‐temporal modeling to follow species density redistributions. In light of our global assessment, we establish a framework for improving the management and conservation of transboundary and migrating marine demersal species. We provide directions to improve data availability and encourage countries to share survey data, to assess species vulnerabilities, and to support management adaptation in a time of climate‐driven ocean changes.

我们准备好追踪气候驱动的跨越国际边界的海洋物种变化了吗？ ‐ 科学底拖网数据的全球调查
为了应对气候变化和海景变化，海洋生物群正在快速重新分布。虽然鱼类种群和群落结构的变化威胁着渔业的可持续性，但由于生物观测数据不连续、缺乏数据可用性以及数据与实际物种分布不匹配，我们通过跟踪和预测海洋物种来适应的能力仍然是一个挑战。为了评估这一挑战的严重程度，我们回顾了正在进行的科学底拖网调查的全球状况和可及性。总的来说，我们从 2001 年至 2019 年定期进行的 95 项调查中收集了 283,925 个样本的元数据。我们发现收集的元数据中有 59% 不是公开的，这凸显了数据的可用性是评估全球物种重新分布的最重要挑战。气候变化。鉴于调查的主要目的是提供独立数据，为重要商业种群的种群评估提供信息，我们进一步强调，单一调查并未涵盖主要商业底层鱼类的全部范围。平均需要 18 次调查才能覆盖至少 50% 的物种范围，这证明了结合多项调查来评估物种范围变化的重要性。我们评估了结合调查来跟踪跨境物种重新分布的潜力，并表明可以通过时空模型来克服采样方案的差异和采样的不一致，以跟踪物种密度的重新分布。根据我们的全球评估，我们建立了一个框架，以改善跨境和迁徙海洋底层物种的管理和保护。 我们提供改善数据可用性的指导，鼓励各国共享调查数据，评估物种脆弱性，并支持气候驱动的海洋变化时期的管理适应。
