This paper develops a risk table to facilitate incorporation of additional information into the fisheries stock assessment and management process. The risk table is designed to evaluate unanticipated ecosystem and environmental impacts on marine resources that may require a rapid management response. The risk table is a standardized framework to document concerns about the assessment model, population dynamics, and the ecosystem/environment that are not explicitly addressed within the stock assessment model. A scoring procedure is used to evaluate the severity of the concern. These concerns can then be evaluated in support for or against a reduction from the maximum Acceptable Biological Catch while providing reviewers and stakeholders transparent documentation of the concerns. The risk table was applied successfully to several stocks on a trial basis during the 2018 groundfish assessment cycle for the North Pacific Fishery Management Council, and will be used for all full groundfish assessments in 2019. Rapid changes in climate are likely for Alaska marine ecosystems in coming decades, and these changes are not entirely predicable. Therefore, we avocate that the risk table approach should be included in the suite of management tools used to address the effects of climate change on Alaska marine resources.

制定渔业捕捞建议时可解决种群评估以外问题的风险表

本文拟定了一个风险表,以促进将更多信息纳入渔业种群评估和管理过程。风险表旨在评估可能需要快速管理层响应的生态系统和环境对海洋资源的意外影响。风险表是一个标准化的框架,用于记录有关评估模型,种群动态以及生态系统/环境的问题,这些问题在种群评估模型中未明确解决。评分程序用于评估问题的严重性。然后可以评估这些关注点,以支持或反对最大可接受生物捕捞量的减少,同时为审核者和利益相关者提供关注点的透明文档。该风险表已在北太平洋渔业管理委员会的2018年底层鱼类评估周期中成功地试用了几只种群,并将用于2019年的所有完整底层鱼类评估。阿拉斯加海洋生态系统的气候可能迅速变化。未来几十年,这些变化并非完全可以预测。因此,我们提倡将风险表方法纳入用于解决气候变化对阿拉斯加海洋资源影响的管理工具套件中。
