Abstract

Progress towards ecosystem-based fisheries management calls for useful tools to prioritize actions. To select suitable methods for local circumstances, evaluating approaches used in other jurisdictions can be a cost-effective first step. We tested Productivity Susceptibility Analysis (PSA) to assess the potential vulnerability of the marine fish community in the Skagerrak–Kattegat (Eastern North Sea) to possible interactions with all Swedish fisheries operating in the area. This analysis combines attributes for a species productivity with attributes related to the susceptibility to capture to quantify a single score for vulnerability: high, medium, or low risk. Results indicate that demersal trawl and gillnet fisheries were associated with the highest risk levels if interaction occurs, i.e. having the highest prevalence of species with potentially high vulnerability to the fisheries. Mixed results were seen when comparing the assessment results with available data. The main benefit of utilizing PSA in the area is the comprehensiveness of the assessment, including data-deficient fisheries and species. Drawbacks include potential overestimation of actual risks. Overall, together with available data, PSA in the studied area provides a comprehensive map of potential risks for further actions and may progress a science-based, precautionary management of the area.

基于风险的Skagerrak–Kattegat海洋鱼类群落对瑞典渔业的脆弱性评估

摘要

在基于生态系统的渔业管理方面取得进展，需要有用的工具来确定行动的优先次序。为了选择适合当地情况的方法，评估在其他辖区使用的方法可能是具有成本效益的第一步。我们对生产率敏感性分析（PSA）进行了测试，以评估Skagerrak–Kattegat（东部北海）中海水鱼类群落与该地区所有瑞典渔业之间可能存在的相互作用的潜在脆弱性。该分析将物种生产力的属性与与捕获的敏感性相关的属性相结合，以量化脆弱性的单个评分：高，中或低风险。结果表明，如果发生相互作用，则深海拖网和刺网渔业的风险最高，即 具有最高流行率的物种，对渔业可能具有很高的脆弱性。将评估结果与可用数据进行比较时，看到了混合结果。在该地区利用PSA的主要好处是评估的全面性，包括缺乏数据的渔业和物种。缺点包括实际风险的潜在高估。总体而言，所研究地区的PSA与可用数据一起，为进一步采取行动提供了潜在风险的全面地图，并可能对该地区进行基于科学的预防性管理。缺点包括实际风险的潜在高估。总体而言，所研究地区的PSA与可用数据一起，为进一步采取行动提供了潜在风险的全面地图，并可能对该地区进行基于科学的预防性管理。缺点包括实际风险的潜在高估。总体而言，所研究地区的PSA与可用数据一起，为进一步采取行动提供了潜在风险的全面地图，并可能对该地区进行基于科学的预防性管理。
