Industrial-scale harvest of species at risk of extinction is controversial and usually highly regulated on land and for charismatic marine animals (e.g. whales). In contrast, threatened marine fish species can be legally caught in industrial fisheries. To determine the magnitude and extent of this problem, we analyze global fisheries catch and import data and find reported catch records of 91 globally threatened species. Thirteen of the species are traded internationally and predominantly consumed in European nations. Targeted industrial fishing for 73 of the threatened species accounts for nearly all (99%) of the threatened species catch volume and value. Our results are a conservative estimate of threatened species catch and trade because we only consider species-level data, excluding group records such as 'sharks and rays.' Given the development of new fisheries monitoring technologies and the current push for stronger international mechanisms for biodiversity management, industrial fishing of threatened fish and invertebrates should no longer be neglected in conservation and sustainability commitments.
工业规模捕捞濒危物种颇具争议，在陆地和受追捧的海洋动物（如鲸鱼）方面，通常受到高度监管。相比之下，受威胁的海洋鱼类可在工业渔业中合法捕捞。为了确定这一问题的严重程度和范围，我们分析了全球渔业捕捞和进口数据，发现了 91 种全球受威胁物种的报告捕捞记录。其中 13 种物种在国际上进行交易，主要在欧洲国家消费。针对 73 种受威胁物种的有针对性的工业捕捞，几乎占据了受威胁物种捕捞量和价值的全部（99%）。由于我们仅考虑物种层面的数据，不包括“鲨鱼和鳐鱼”等群组记录，因此我们的研究结果是对受威胁物种捕捞和贸易的保守估计。鉴于新的渔业监测技术的发展以及当前对加强生物多样性管理国际机制的推动，在保护和可持续性承诺中，不应再忽视对受威胁鱼类和无脊椎动物的工业捕捞。
