The Rio Doce is a very important freshwater system in Brazil running through the Atlantic Forest, however available information about its biodiversity is scarce. In 2015, the Rio Doce basin was damaged by a burst of Fundão tailing dam in Mariana (Minas Gerais) causing an extraordinary environmental damage, with consequences still incompletely known. In the present paper we analyzed 6042 latitude/longitude records of 208 fish species from the Rio Doce deposited in collections prior to November 2015, in order to identify areas of endemism in the river before the burst. Several areas of endemism were identified along the basin, most of them describing small and novel patterns. Our analyses helped to identify areas of major diversity along the basin as well as information gaps concerning fish sampling. We hope this contribution will help obtaining quantitative measures on the impact caused by the Fundão dam catastrophe on fish biodiversity and will be useful to orient general actions towards the restoration of the basin.
里奥杜西是巴西一条非常重要的淡水河流，流经大西洋森林，但有关其生物多样性的信息却很少。2015 年，里奥杜西流域的法顿尾矿坝溃坝，对马里亚纳（米纳斯吉拉斯州）造成了巨大的环境破坏，其后果仍不完全清楚。在本文中，我们分析了 6042 条 208 种鱼类的经纬度记录，这些记录来自于 2015 年 11 月之前保存在收藏中的里奥杜西的数据，以便在溃坝前确定该河流的特有种区域。在流域范围内确定了几个特有种区域，其中大多数描述了小而新颖的模式。我们的分析有助于确定流域内的主要多样性区域，以及有关鱼类采样的信息空白。我们希望这一贡献将有助于对法顿大坝灾难对鱼类生物多样性造成的影响进行定量评估，并为恢复流域提供指导。
