Prime locations are consistently associated with structure and changes in depth. Fallen trees, known locally as "galhadas," are exceptionally productive, especially for Tucunaré and Traíra. The confluence areas where smaller streams or igarapés meet the main river attract baitfish and, consequently, predators. Deep pools, particularly those with undercut banks or rocky ledges, hold larger fish during the heat of the day. Backwater lagoons (lagoas) connected to the main river are hotspots during the dry season, often holding high concentrations of fish.
