Ichthyofauna of the Ribeirão Frutal and tributaries, upper Rio Paraná basin, Minas Gerais, Southeastern Brazil

Abstract: The Ribeirão Frutal basin is located within the upper Rio Paraná system, in the Frutal municipality, Minas Gerais State, Southeastern Brazil. Until now, there was no complete ichthyological survey published for this small basin. Therefore, here we provided a list of fish species from the Ribeirão Frutal and some of its tributaries. We found 31 species of fishes representing five orders and ten families. We identify a likely undescribed and five non-native species in the Frutal basin. Lastly, we recommend new surveys of fishes in small hydrographic basins within upper Rio Paraná system.

摘要：里贝朗弗鲁塔尔流域（Ribeirão Frutal Basin）位于巴西东南部米纳斯吉拉斯州弗鲁塔尔市境内，隶属于巴拉那河上游水系。迄今为止，该小型流域尚未有完整的鱼类学调查成果发表。为此，本研究梳理了里贝朗弗鲁塔尔流域及其部分支流的鱼类物种名录。本次调查共记录鱼类31种，隶属于5目10科。研究发现该流域内存在1个疑似未描述物种及5个外来物种。最后，本研究建议对巴拉那河上游水系内的小型水文流域开展新一轮鱼类调查。
