Abstract The northernmost commercial fisheries in the world take place in the northern Barents Sea up to around 80° N. This is an area where global warming is particularly intense and where large, previously ice-covered areas are now more accessible to fishing vessels. This raised questions whether existing conservation and management measures are adequate. In this paper, we discuss the process of developing new regulatory measures, including four large preliminary closed areas covering 442,022 km2 and an additional ten closed areas covering more than 3260 km2 that protects sites with biodiversity, specific to the region. The new measures, an amendment to an old regulation related to the management of impacts from bottom fisheries on ecosystems, is based on knowledge derived from more than 10 years of scientific surveys of the seabed ecology. A key finding here is that cost-efficient, large-scale mapping and monitoring of seabed ecosystems is important for the development of area-based regulations of fishing activities. In the process of developing the regulation the Directorate of Fisheries made its own analysis of the data from the scientific surveys by a novel approach using commercially available software. Such area-based measures also contribute to the achievement of Aichi target 11 and UN Sustainable Development Goal 14.5 on protecting maritime areas.

应对全球变暖：北极的新渔业管理措施

摘要 世界上最北端的商业渔业发生在北纬 80 度左右的巴伦支海北部。这是一个全球变暖特别严重的地区，以前被冰覆盖的大面积区域现在更容易被渔船进入。这提出了现有保护和管理措施是否足够的问题。在本文中，我们讨论了制定新监管措施的过程，包括占地 442,022 平方公里的四个大型初步封闭区和占地超过 3260 平方公里的额外十个封闭区，这些封闭区保护具有特定于该地区的生物多样性的地点。新措施是对与管理底层渔业对生态系统影响有关的旧法规的修订，其依据是从 10 多年的海底生态科学调查中获得的知识。这里的一个关键发现是，对海底生态系统进行经济高效的大规模测绘和监测对于制定基于区域的捕捞活动法规很重要。在制定法规的过程中，渔业局使用商业软件通过一种新颖的方法对科学调查的数据进行了自己的分析。这种基于区域的措施也有助于实现爱知目标 11 和联合国可持续发展目标 14.5 保护海域。在制定法规的过程中，渔业局使用商业软件通过一种新颖的方法对科学调查的数据进行了自己的分析。这种基于区域的措施也有助于实现爱知目标 11 和联合国可持续发展目标 14.5 保护海域。在制定法规的过程中，渔业局使用商业软件通过一种新颖的方法对科学调查的数据进行了自己的分析。这种基于区域的措施也有助于实现爱知目标 11 和联合国可持续发展目标 14.5 保护海域。
