自1996年以来，世界自然保护联盟（IUCN）的标准一直被用于将海洋鱼类分类为濒危物种，但迄今为止还没有对深海鱼类进行评估——尽管它们由于某些生活史特征而容易受到侵略性深海捕捞的影响。在这里，我们使用研究调查数据来显示，在西北大西洋的加拿大水域，有五种深海鱼类在17年的时间里数量下降，达到了国际自然保护联盟的极度濒危标准。我们的研究结果表明，需要采取紧急行动来实现深海渔业的可持续管理。
Criteria from the World Conservation Union (IUCN) have been used to classify marine fish species as endangered since 1996, but deep-sea fish have not so far been evaluated — despite their vulnerability to aggressive deepwater fishing as a result of certain life-history traits. Here we use research-survey data to show that five species of deep-sea fish have declined over a 17-year period in the Canadian waters of the northwest Atlantic to such an extent that they meet the IUCN criteria for being critically endangered. Our results indicate that urgent action is needed for the sustainable management of deep-sea fisheries.
