Endemic fish wiped out in Brazilian Amazon hydroelectric dam area, study finds

The Balbina hydroelectric dam in the Brazilian Amazon caused the extinction of seven endemic fish species in the Uatumã River due to habitat transformation. Researchers suggest exploring unaffected tributaries for potential species refuge. The study highlights the broader threat of hydropower dams, industrial fishing, and climate change on Amazonian fish populations. The dam’s impact on indigenous livelihoods and the environment has been recognized, prompting calls for conservation efforts and alternative energy sources.
