Ecological risk assessments are important as scientific support for the implementation of ecosystem-based fisheries management. Marine invertebrates are important to ecosystem structure and function and may be sensitive to fishing pressure. Some are also of increasing commercial value – but have hitherto not been paid much attention to in ecological risk assessments. Here, catches of invertebrates in Swedish west-coast fisheries with demersal trawls and creels are examined from an ecological risk assessment perspective. It is found that few non-commercial invertebrate species have been regularly recorded in onboard observer programs. Furthermore, for being a comparatively well-studied area, it is striking to find that out of the 93 species included, 56% could be classified as data deficient in terms of known attributes needed to perform basic ecological risk assessments. This implies that there is little or no available information on the basic life history traits important for estimating productivity. Additionally, onboard observer data for invertebrates are inadequate beyond targeted commercial species for robust statistical analysis on volumes generated over time and between fisheries. However, over 18% of the studied species are categorized as red-listed on the Swedish IUCN Red List. Combined with the few records available in observer data programs, the study illustrates the need to pay more attention to marine invertebrates in fisheries monitoring programs and research, especially bycaught and non-commercial invertebrate species.

瑞典西海岸渔业捕获的无脊椎动物的生态风险评估

生态风险评估对于实施基于生态系统的渔业管理具有重要的科学支撑。海洋无脊椎动物对生态系统的结构和功能很重要，并且可能对捕捞压力敏感。有些还具有不断增加的商业价值，但迄今为止在生态风险评估中尚未受到足够重视。在这里，从生态风险评估的角度审查了瑞典西海岸渔业中使用底拖网和鱼架捕获的无脊椎动物。研究发现，船上观察员计划定期记录的非商业无脊椎动物物种很少。此外，作为一个研究相对充分的领域，令人惊讶的是，在所纳入的 93 个物种中，56% 的物种在执行基本生态风险评估所需的已知属性方面可被归类为数据不足。这意味着关于对估计生产力很重要的基本生活史特征的可用信息很少或根本没有。此外，除了目标商业物种之外，船上无脊椎动物的观察者数据不足以对一段时间内和渔业之间产生的数量进行可靠的统计分析。然而，超过 18% 的研究物种被列入瑞典 IUCN 红色名录。结合观察者数据计划中可用的少量记录，该研究表明需要在渔业监测计划和研究中更多地关注海洋无脊椎动物，特别是兼捕和非商业无脊椎动物物种。
