Fishing near Duque de Caxias, Rio de Janeiro

Duque de Caxias sits on the western shore of Guanabara Bay in the Rio de Janeiro metropolitan area, surrounded by a network of rivers draining the Serra do Mar. The bay itself and the nearby lowland rivers — including the Rio Iguaçú just a few kilometers away — are the main draws for local anglers, with freshwater fishing in the river channels and estuarine fishing where those rivers meet the bay.
