Large oceanic migrants play important roles in ecosystems, yet many species are of conservation concern as a result of anthropogenic threats, of which incidental capture by fisheries is frequently identified. The last large populations of the leatherback turtle, Dermochelys coriacea, occur in the Atlantic Ocean, but interactions with industrial fisheries could jeopardize recent positive population trends, making bycatch mitigation a priority. Here, we perform the first pan-Atlantic analysis of spatio-temporal distribution of the leatherback turtle and ascertain overlap with longline fishing effort. Data suggest that the Atlantic probably consists of two regional management units: northern and southern (the latter including turtles breeding in South Africa). Although turtles and fisheries show highly diverse distributions, we highlight nine areas of high susceptibility to potential bycatch (four in the northern Atlantic and five in the southern/equatorial Atlantic) that are worthy of further targeted investigation and mitigation. These are reinforced by reports of leatherback bycatch at eight of these sites. International collaborative efforts are needed, especially from nations hosting regions where susceptibility to bycatch is likely to be high within their exclusive economic zone (northern Atlantic: Cape Verde, Gambia, Guinea Bissau, Mauritania, Senegal, Spain, USA and Western Sahara; southern Atlantic: Angola, Brazil, Namibia and UK) and from nations fishing in these high-susceptibility areas, including those located in international waters.
大型海洋洄游动物在生态系统中发挥着重要作用，但由于人为威胁，许多物种仍受到保护关注，其中渔业的偶然捕捞经常被确定为威胁之一。棱皮龟（Dermochelys coriacea）的最后一个大型种群存在于大西洋，但与工业渔业的相互作用可能危及最近的积极种群趋势，因此减少兼捕成为当务之急。在这里，我们首次对大西洋棱皮龟的时空分布进行了泛大西洋分析，并确定了与延绳钓渔业努力的重叠。数据表明，大西洋可能由两个区域管理单元组成：北部和南部（后者包括在南非繁殖的海龟）。尽管海龟和渔业的分布高度多样化，但我们强调了九个容易受到潜在兼捕影响的高风险区域（北部大西洋有四个，南部/赤道大西洋有五个），这些区域值得进一步进行有针对性的调查和缓解。在这八个地点都有报道称棱皮龟被意外捕获，这进一步证实了这一点。需要开展国际合作，特别是来自那些在其专属经济区内可能容易受到兼捕影响的国家（北部大西洋：佛得角、冈比亚、几内亚比绍、毛里塔尼亚、塞内加尔、西班牙、美国和西撒哈拉；南部大西洋：安哥拉、巴西、纳米比亚和英国），以及在这些高风险区域捕鱼的国家，包括那些位于国际水域的国家。
