Productive areas are found along the entire river but are often associated with specific structures. Confluences with smaller tributaries or streams attract bait and predators. The numerous permanent and semi-permanent lagoons connected to the main river, known as "baias" or "corixos," are hotspots, especially during the dry season. Submerged timber, known as "galhadas," and undercut banks provide essential cover for peacock bass. Islands and sandbars create current breaks that hold fish.
