Fishing in Parque Nacional da Chapada Diamantina

The Parque Nacional da Chapada Diamantina sits in the Serra do Sincorá, in the state of Bahia, covering 152,000 hectares where the Mata Atlântica, Cerrado, and Caatinga meet.

The park's terrain — quartzite ridges, rocky campos rupestres, and periodically flooded lowlands — shapes water that runs clear and cold off the high ground before slowing into pools, wetlands, and river corridors below.

The Rio Paraguaçu and its tributaries are the main drainage system, and the watershed holds more than 60 fish species, a significant number of them endemic to the region. The Rio Paraguaçu itself is the backbone of the park's fishing.

Its upper reaches run through the park's core, and the water clarity is exceptional — fish are often visible at distance in the pools between rapids.

Traíra hold in the deeper remansos and around submerged structure; piau and lambari work the current edges below corredeiras.

The tucunaré, an introduced species, appears in the system but is more associated with the lower Paraguaçu than the park's interior waters.

The Marimbus — a seasonally flooded wetland area on the park's eastern edge, sometimes called the Pantanal da Chapada Diamantina — sits near the confluence of rivers draining toward Andaraí.

The mix of flooded vegetation, lagoas, and slow channels creates different holding water than the rocky upland rivers, and local communities around the Remanso settlement have fished these waters traditionally for generations.

Other rivers within or adjacent to the park — the Rio Preto, Rio Santo Antônio, Rio Garapa, and Rio do Caldeirão (also known as Roncador) — drain the park's varied terrain and carry the same native assemblage: traíra, piau, lambari, piaba, and cascudos on the rocky substrate.

Blind catfish have been documented in cave systems within the park, a reminder of how isolated and specialized this ichthyofauna is.

The park is administered by ICMBio, and fishing regulations here fall under federal protected-area rules rather than standard state licensing alone.

Before fishing anywhere inside the park boundaries, check directly with ICMBio for current rules — the distinction between park interior and the surrounding APA de Marimbus-Iraquara matters, and the rules are not the same in both zones.

This is not water you come to for large fish. You come because the rivers are clear, the species are genuinely unusual, and the fishing sits inside one of the more ecologically complex landscapes in Brazil.
