Key areas include deep holes adjacent to submerged or fallen trees, known locally as "galhadas." The mouths of tributary streams and creeks where they meet the Rio Novo create nutrient-rich confluences that attract baitfish and predators. Long, deep runs with undercut clay or root-strewn banks are prime lies for large catfish and Traíra. Sandbars and points that create current breaks are reliable spots for Tucunaré and Dorado. Backwater lagoons connected to the main river during high water provide sheltered, food-rich environments.
