Productive areas are typically associated with structure and changes in current. Confluences where smaller streams or igarapés meet the main river channel are always worth exploring, as they funnel food and attract predators. Submerged timber, fallen trees, and logjams provide excellent cover for Peacock Bass and catfish. Sandbars and points that create current seams are also reliable spots. Deep pools at the base of rapids or river bends often hold larger specimens of Payara and catfish. Backwater lagoons, accessible during the dry season, can be hotspots for concentrated fish activity.
