Productive areas include confluence zones, such as where the Rio Santo Antônio meets the Rio Araguari, which often create current seams and deep holes holding large fish. Isolated lagoons and "igarapés" (smaller forest streams) connected to the main river are excellent habitats for Peacock Bass and Aruanã, especially as water levels recede. Areas with submerged timber, fallen trees, and undercut banks along the main river channel are prime ambush points for predators.
