Fishing near Mucajaí, Roraima

Mucajaí sits in Roraima, Brazil's northernmost state, where the Rio Mucajaí runs just 2 km from town before joining the larger Rio Branco nearby. The surrounding landscape shifts between Amazonian forest and open savanna, laced with smaller igarapés — Igarapé Azul, Igarapé Arara, Igarapé Traíra — that feed the main channels. These waters draw local anglers year-round for piranha, aracu, and other native species typical of the upper Rio Branco basin.
