Rio Catarina is a river located in the state of Piauí, in northeastern Brazil. Flowing through a region characterized by the semi-arid landscape typical of the Brazilian interior, this waterway is part of a broader network of rivers and streams that drain the Piauí region. The river supports a modest but notable fishery, with the spotted pimelodus standing out as the top-targeted species among local anglers. Like many rivers in this part of Brazil, Rio Catarina reflects the ecological character of the northeastern interior — a dynamic environment shaped by seasonal rainfall patterns and the rugged terrain of the region.

Deeper pools and areas of slower current are the most productive holding zones for spotted pimelodus on Rio Catarina. Submerged structure, undercut banks, and areas near confluences with smaller tributaries or riachos are prime locations to target. During lower water conditions of the dry season, these deeper sections become concentration points for fish seeking refuge from the heat and reduced oxygen levels in shallower areas.
