The Rio Mamiá is a significant blackwater tributary flowing through the heart of the Amazon rainforest in Amazonas, Brazil. This river is characterized by its dark, tea-colored water, a result of tannins leaching from decaying vegetation, which creates a unique and challenging environment for anglers. The river winds through dense jungle, featuring a mix of deep channels, submerged timber, and flooded forest areas known as igapós, providing diverse and productive habitat for a remarkable array of iconic Amazonian sportfish.
