Uatumã River
The Uatumã River (sometimes spelled Uatamã) is a river flowing through the state of Amazonas in Brazil. It is a northern tributary of the Amazon River, and known for its extensive peacock bass population. It is a blackwater river. The river flows through the Uatuma-Trombetas moist forests ecoregion. During the wet season starting in December, water levels can rise some 25 to 40 feet. Water levels have been strongly affected by the building of the controversial Balbina Dam on the river in the mid to late 1980s to generate electricity. The hydroelectric dam generates an average of 112.2 MW of electricity from the river system and floods a total of 2360 km2 of rainforest around the Uatumã river. From the point where the river emerges from the dam it defines the east boundary of the Caverna do Maroaga Environmental Protection Area, established in 1990. The Uatumã Biological Reserve established in 1990 is a nature reserve around the river in the municipalities of São ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blackwater River
A blackwater river is a type of river with a slow-moving channel flowing through forested swamps or wetlands. As vegetation decays, tannins leach into the water, making a transparent, acidic water that is darkly stained, resembling black tea. Most major blackwater rivers are in the Amazon Basin and the Southern United States. The term is used in fluvial studies, geology, geography, ecology, and biology. Not all dark rivers are blackwater in that technical sense. Some rivers in temperate regions, which drain or flow through areas of dark black loam, are simply black due to the color of the soil; these rivers are ''black mud rivers''. There are also black mud estuaries. Blackwater rivers are lower in nutrients than whitewater rivers and have ionic concentrations higher than rainwater. The unique conditions lead to flora and fauna that differ from both whitewater and clearwater rivers. The classification of Amazonian rivers into black, clear, and whitewater was fir ...

Peacock Bass
Peacock bass or Brazilian tucunaré are large freshwater cichlids of the genus ''Cichla''. These are diurnal predatory fishes native to the Amazon and Orinoco basins, as well as rivers of the Guianas, in tropical South America. They are sometimes referred to in English by their Brazilian name ''tucunaré'' or their Spanish name ''pavon''. Despite the common name and their superficial similarity, they are not closely related to other fish known as bass, such as the North American largemouth bass (''Micropterus salmoides''). Peacock bass are important food fish and also considered valuable game fish. This has resulted in their accidental (escapees from fish farms) or deliberate (release by fishers) introduction to regions outside their native range, both elsewhere in South America, and in warm parts of North America and Asia. Singles have been caught elsewhere, including Australia, but do not appear to have become established there. Where established as an introduced species, t ...
