Productive areas are consistently found around any significant structure. Key spots include the mouths of smaller tributaries and igarapés (small streams), which funnel baitfish. Deep pools adjacent to sandbars and points are holding areas for larger predators. Areas with extensive submerged timber and root masses along the banks are prime ambush points for Peacock Bass. The confluence zone where the Rio Uaicurapá meets the Rio Negro can be especially productive, as it creates current seams and eddies that attract Payara and large catfish.
