Productive fishing areas are found along the entire river course. Confluences with tributaries, like the Rio Jaminauá, are often hotspots as they create current seams and bring in nutrients. Areas with significant structure—such as fallen trees, undercut banks, and rocky outcrops—hold predatory fish. Backwater lagoons and oxbow lakes connected to the main river during high water can be exceptionally productive for a variety of species once they become isolated pools in the dry season.
