Baboso
The barba-chata is a large pimelodid catfish native to the Amazon basin, where it moves through the deepest river channels on long migrations between the estuary and Andean foothills.
Commercial fishermen take most of the catch with drifting gillnets during upstream runs, but the species also turns up in artisanal and subsistence fisheries across the Central Amazon and border regions with Colombia and Peru.
Scientific Name: Brachyplatystoma platynemum
Also known as Barba-chata, Barbado, Babão, Xeréu
- Light grey or brown on the back, fading to a lighter belly, with no spots or stripes — a plain, unmarked body that distinguishes it from spotted pimelodids.
- Head is compressed and elongated; barbels are notably long, broad, and flattened — the feature that gives the fish its Portuguese name, barba-chata (flat beard).
- Caudal fin is deeply forked with narrow lobes in adults, a useful field mark when separating it from related goliath catfish.
- Reaches around 130 cm and over 10 kg; females tend to run larger than males, which average around 65 cm to the females' 75 cm.
What to know
Habitat Distribution
- Native to the Amazon basin in Brazil, including the Central Amazon, Lower Amazon, and the estuary; also present in the Brazilian-Colombian-Peruvian border region, which accounts for the bulk of recorded catches.
- Lives in the deepest channels of large rivers, over sand, stones, and driftwood — a bottom-oriented fish that avoids shallow floodplain waters.
- The freshwater estuary serves as nursery habitat for juveniles; adults migrate upstream toward Andean foothills to spawn.
- Also recorded in the Pará region and northwestern Brazil near the Orinoco drainage boundary.
Key Locations
- Brazilian-Colombian-Peruvian border region — accounts for roughly 77% of recorded barba-chata catches in Brazilian waters.
- Central Amazon — secondary catch zone, particularly in large main-channel rivers near Manaus.
- Amazon estuary (Pará) — important nursery area for juveniles and a point of capture during downstream movements.
- Lower Amazon — part of the migration corridor between the estuary and upstream spawning grounds.
Specific Spots
- Deep main-channel runs with sand and gravel substrate — this fish hugs the bottom of the largest, fastest water it can find.
- Confluences and channel bends where current concentrates baitfish schools during upstream migration pushes.
- Driftwood and submerged structure on deep channel edges give the fish a place to hold between feeding movements.
Baboso FAQ
Answers from onWater's species guide.
What are the best lures and bait for Baboso?
Live or fresh-cut characins (curimatã, sardinha) are the most direct match to the fish's natural diet and the standard approach in commercial and artisanal fisheries. Large deep-diving plugs and heavy jigs (60–100 g) worked along the bottom of main-channel runs can draw strikes during active migration periods.
When is the best time to fish for Baboso?
Migration runs bring fish through different parts of the Amazon system at various times of year; the species does not have a single narrow peak season. Estuary and lower river areas see fish during downstream juvenile movements; upper river and border regions see adults during upstream spawning migrations.
How do you catch Baboso?
Most barba-chata in Brazil are taken by commercial fishermen using drifting gillnets set in deep main-channel water during upstream migration runs. Artisanal anglers fish heavy bottom rigs with live or cut baitfish in the same deep-channel zones, working confluences and channel bends where migrating fish concentrate.
What do Baboso eat?
Feeds entirely on other fish, primarily characins like Prochilodus (curimatã), Anodus, and Astyanax. Large baitfish profiles work best: deep-diving plugs or heavy jigs that sink into the channel and imitate a mid-sized characin.
Where do Baboso live?
Native to the Amazon basin in Brazil, including the Central Amazon, Lower Amazon, and the estuary; also present in the Brazilian-Colombian-Peruvian border region, which accounts for the bulk of recorded catches.
