Sábalo
Curimbatá is one of the most abundant fish in Brazil's southern river systems — a bottom-grazing schooler that can make up more than half the fish biomass in a given stretch of river.
Commercial and artisanal fishermen in the Paraná-Paraguay basin and Pantanal have depended on it for generations. Recreational anglers target it with simple bottom rigs, particularly during its dramatic upstream spawning runs.
Scientific Name: Prochilodus lineatus
Also known as Curimbatá, Curimba, Corimbatá, Grumatã, Sábalo
- Tall, laterally compressed body; greenish-gray on the back and sides, fading to a lighter belly, with yellowish-green fins and faint horizontal streaking.
- The mouth is circular and protrudes forward — adapted for scraping biofilm and detritus off hard surfaces, which makes it immediately recognizable from other species.
- Common fish run around 45 cm (roughly 18 inches); larger individuals reach 80 cm and can push 9 kg (20 lb), though fish over 5 kg are considered a good catch today.
What to know
Habitat Distribution
- Native to the Paraná-Paraguay basin — one of Brazil's most productive river systems — as well as the Paraíba do Sul drainage in the southeast.
- Also present in the Lagoa dos Patos system and surrounding rivers in Rio Grande do Sul, with a confirmed range extension into Mirim Lagoon at the extreme south of Brazil.
- Favors large, turbid rivers with sand or mud bottoms and connected floodplains; the Pantanal wetlands of Mato Grosso do Sul hold significant populations, including in the Touro Morto River.
Key Locations
- Lower Paraná River basin — the historical center of curimbatá commercial fisheries and still the most productive region for the species in Brazil.
- Pantanal wetlands, Mato Grosso do Sul — including the Touro Morto River, where large schools have been documented in the floodplain system.
- Paraíba do Sul basin, southeastern Brazil — part of the species' native range and supporting regional artisanal fisheries.
- Lagoa dos Patos and Mirim Lagoon, Rio Grande do Sul — the southern limit of the species' confirmed range in Brazil.
Specific Spots
- Deep channel edges and sandy bottom runs where current slows — curimbatá graze these areas systematically, moving along the bottom in schools.
- Floodplain connections and backwater mouths during high water, when fish spread out to feed on detritus-rich sediments deposited by floods.
- Rocky or hard-substrate stretches during spawning migrations, where fish stage before pushing upstream — these concentrations are the most reliable windows for anglers.
Sábalo FAQ
Answers from onWater's species guide.
What are the best lures and bait for Sábalo?
Dough baits, fermented corn, and masa-style paste baits are the go-to offerings; the bait needs to sit on the bottom and carry a strong organic scent to draw fish in. Small pieces of aquatic vegetation or algae-coated material can also work, mimicking the biofilm the fish naturally graze on.
When is the best time to fish for Sábalo?
Spawning migrations typically coincide with rising water and warming temperatures in spring and early summer (roughly October–December in the Paraná basin), concentrating fish and creating the best fishing of the year.
How do you catch Sábalo?
Most anglers fish curimbatá from the bank or from small boats anchored in current, using bottom rigs baited with dough or fermented paste. The most productive windows are during upstream spawning migrations, when large schools concentrate in river channels and staging areas.
What do Sábalo eat?
Feeds almost entirely on biofilm, algae, and detritus scraped from the river bottom, its circular, protruding mouth is built for exactly this.
Where do Sábalo live?
Native to the Paraná-Paraguay basin, one of Brazil's most productive river systems, as well as the Paraíba do Sul drainage in the southeast. Also present in the Lagoa dos Patos system and surrounding rivers in Rio Grande do Sul, with a confirmed range extension into Mirim Lagoon at the extreme south of Brazil.
