An analysis of red king crab bycatch in bottom-trawl fisheries in the Russian exclusive economic zone (EEZ) in the Barents Sea based on data collected from 2010 to 2019 shows an annual range of 2.2–9.8 thousand tonnes of crab bycatch from 2010 to 2018, which is 0.7–2.9% of the total biomass of red king crab in the EEZ. It was found that the catch of commercially valuable male crabs in the bottom-trawl fishery ranged from 1.4 to 6.5 thousand tonnes, which is ∼0.7–3.3% of the total commercial stock. A protected area created in 2006 is estimated to prevent the catch of 1.1–4.8 thousand tonnes of crab; however, protective measures do not take into account the peculiarities of the current distribution of crab populations and the geography of the fishing area. This work offers suggestions for improving the regulatory measures to protect the king crab stock in Russian waters of the Barents Sea.

俄罗斯巴伦支海水域底层鱼类渔业中红帝王蟹的兼捕:评估和规定

根据 2010 年至 2019 年收集的数据,对巴伦支海俄罗斯专属经济区 (EEZ) 底拖网渔业中红王蟹兼捕的分析显示,2010 年至 2018 年的年蟹兼捕量为 2.2-980 吨,占专属经济区红帝王蟹总生物量的 0.7-2.9%。结果表明,底拖网渔业中具有商业价值的雄蟹捕捞量为 1.4 至 6500 吨,占商业总存量的 0.7-3.3%。2006 年建立的保护区估计可防止捕获 1.1-4.8 万吨螃蟹;然而,保护措施没有考虑到目前螃蟹种群分布的特点和捕捞区的地理情况。
