Vaupés河因其众多急流而成为亚马逊河流域内为数不多的河流之一。这些河流快速流动的部分不仅为高度专业化的鱼类提供了栖息地,而且还充当了阻碍鱼类沿其运动的天然屏障。在哥伦比亚瓦普斯河下游流域的一次捕鱼探险中,注册了95种,属于30科和7目。尽管该地区最近有库存,我们的全面采样工作特别集中在急流和相关的流变动物区系,允许我们贡献哥伦比亚四种鱼类的第一批记录(MylopluslucienaeAndrade,Ota,Bastos&Jégu,2016年,TometesmakueJégu,Santos&Jégu,2002年,也是该属的第一个记录,Leptodoraspraelongus(Myers&Weitzman,1956),和EigenmanniamatintapereiraPeixoto,Dutra&Wosiacki,2015年)和六个可能未描述的物种(即,Jupiabasp.,Moenkhausiasp.,Phenacogastersp.,Bunocephalussp.,Hemiancistrussp.,和Archolaemussp.).在这项研究中,列出了这些环境中的鱼类动物的评论列表,以及纳入哥伦比亚CaVFish项目的鱼类物种的摄影目录。
The Vaupés River stands out as one of the few within the Amazon basin due to its numerous rapids. These riverine fast-flowing sections not only provide habitat to highly specialized fishes but also function as natural barriers hindering the movement of fish along its course. During a fish-collecting expedition in the lower Vaupés River basin in Colombia, 95 species were registered belonging to 30 families and seven orders. Despite recent inventories in the region, our comprehensive sampling efforts particularly focused on the rapids and associated rheophilic fauna, allowing us to contribute the first records of four fish species in Colombia (Mylopluslucienae Andrade, Ota, Bastos & Jégu, 2016, Tometesmakue Jégu, Santos & Jégu, 2002, also first record of the genus, Leptodoraspraelongus (Myers & Weitzman, 1956), and Eigenmanniamatintapereira Peixoto, Dutra & Wosiacki, 2015) and six presumably undescribed species (i.e., Jupiaba sp., Moenkhausia sp., Phenacogaster sp., Bunocephalus sp., Hemiancistrus sp., and Archolaemus sp.). In this study, a commented list of the ichthyofauna of these environments is presented, as well as a photographic catalog of fish species integrated into the CaVFish Project - Colombia.
