The most productive areas are consistently where structure creates ambush points or depth changes. Target the mouths of smaller tributaries where they flow into the main igarapé, as these are natural funnels for baitfish. Deep undercut banks, especially those with overhanging roots or vegetation, hold large Peacock Bass and catfish. Any significant submerged timber, logjams, or fallen trees are prime locations. The deeper pools at the base of riffles or bends in the creek channel are reliable spots to find holding fish.
