Guaporé River

The Guaporé crosses the eastern part of the Beni savanna region. It forms the border of the 615771 ha Guaporé Biological Reserve, and is fed by rivers originating in the reserve, the São Miguel, Branco, São Simão, Massaco and Colorado. About 260 fish species are known from the Guaporé River basin, and about 25 of these are endemic. While many fish species in the river essentially are Amazonian, the fauna in the Guaporé also has a connection with the Paraguay River (part of the Río de la Plata Basin). The Guaporé and the Paraguay, while flowing in different directions, both originate in the Parecis plateau of Brazil. Among the fish species shared between these rivers are the black phantom tetra (important in the aquarium industry) and golden dorado (important in fisheries).
