The Rio Feijão Verde is a significant river system flowing through the state of Paraná in southern Brazil. It is a tributary of the larger Rio Iguaçu system, which is renowned for its diverse and powerful freshwater fish species. The river's name, translating to "Green Bean River," hints at its often verdant, nutrient-rich waters that support a robust aquatic ecosystem. This river offers anglers a chance to pursue some of Brazil's most iconic and hard-fighting freshwater gamefish in a setting that ranges from accessible stretches near population centers to more remote and challenging sections.
