The Uberabinha River is a tributary to the Paranaíba River and, up to now, data about its ichthyofauna was still unknown. Currently the fish community suffers threats due to environmental degradation and the construction of hydroelectric dams. The present study sought to survey the ichthyofauna of the Uberabinha River. Samples were collected in November 2011 and January 2012 using gill nets, cast nets, trawls and sieves. We captured 844 individuals, totaling 36 species of fish. This is the first record of fish from the Uberabinha River and is probably an altered assemblage due to environmental impacts caused by human actions.

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. Keywords: Ichthyology, inventory, Neotropical region, Rio Grande, survey. Ictiofauna do Ribeirão Frutal e afluentes, bacia do alto Rio Paraná, Minas Gerais, Sudeste do BrasilResumo: A bacia do Ribeirão Frutal está localizada no sistema do alto Rio Paraná, no município de Frutal, Estado de Minas Gerais, Sudeste do Brasil. Até o momento, não existe publicação de um levantamento ictiológico completo para essa bacia. Portanto, aqui fornecemos uma lista das species de peixes do Ribeirão Frutal e alguns de seus tributários. Nós encontramos 31 espécies de peixes representando cinco ordens e 10 famílias. Identificamos uma provável espécie não descrita e cinco não nativas na bacia do Frutal. Por fim, recomendamos novos levantamentos de peixes em pequenas bacias hidrograficas do sistema do alto Rio Paraná.

The management of water resources is a complex issue, and the conservation of fish and fishery resources is a growing challenge given the increase in the number of hydroelectric projects in Brazilian river basins. This study describes the fragmentation of the Tocantins–Araguaia River Basin resulting from the installation of hydroelectric plants in operation and planned by the electricity sector until 2050, as well as its relationship with the conservation of fish fauna, especially long-distance migratory species. The hydroelectric projects in operation and planned were analyzed using data obtained from the National Electric Energy Agency. A literature review was carried out to assess the fish species of the Tocantins–Araguaia ecoregion, with an emphasis on long-distance migrants. In general, 75 hydroelectric dams are in operation, and a further 119 projects are in the electricity sector’s plans for construction by 2050 in the Tocantins–Araguaia ecoregion, including a stretch of the basin above the Tucurui dam, which will accentuate the fragmentation in the area. Of the 702 species found in the region, 31.1% are endemic, 6.1% are endangered, and several long-distance migratory species have had their populations restricted. Analysis of this information highlights the widespread impact on the ichthyofauna, affecting both species with a restricted distribution and migratory species with a long-distance distribution. The studies associated with the projects contribute to the advancement of knowledge, but they are only carried out after the works have been defined, which makes it difficult to plan conservation in advance. Transformations in the basin are imminent given the current changes and those expected in the coming years because of the electricity sector’s planning for the region. Considering the inseparable relationship between biodiversity and socio-environmental and cultural diversity, fish conservation is intrinsically linked to the conservation of socio-diversity and the effective participation of local communities from the start of the process. Fish depend on water, and people need both water and aquatic diversity. In conclusion, a well-structured and adaptative conservation plan, combined with the integration of effective fish routes, can contribute to the sustainable development of hydroelectric projects while safeguarding the biodiversity and ecological integrity of the Tocantins–Araguaia Basin.
