Piau verdadeiro
Piau verdadeiro is a native freshwater fish of Brazil's semi-arid northeast, found in river basins across Ceará, Rio Grande do Norte, Paraíba, and the São Francisco drainage.
It's a staple target for local anglers fishing reservoirs and river stretches, valued as table fare and as a reliable catch on light tackle where larger gamefish are scarce.
Scientific Name: Leporinus piau
Also known as Piau, Piau gordura, Piau comum
- Elongated, laterally compressed body typical of the Anostomidae family; silvery to yellowish flanks, often with dark horizontal stripes or spots along the sides.
- Blunt snout and small, firm mouth positioned slightly downward — a useful ID feature that separates it from similar-looking characins in the same water.
- Grows to around 33 cm (roughly 13 inches); most fish caught by anglers run considerably smaller, in the 15–25 cm range.
What to know
Habitat Distribution
- Native to Brazil's semi-arid northeast — originally described from the Salgado River basin in Ceará, with wide distribution across northeastern Brazilian drainages.
- Found in the Acaraú, Banabuiú, Coreaú, Curu, Jaguaribe, Poti, and Salgado river basins of Ceará, as well as basins in Rio Grande do Norte and Paraíba.
- Also present in the São Francisco River basin, including tributaries such as the rio Paraopeba in Minas Gerais, where it has been documented as a migratory species.
- Lives in rivers, streams, and semiarid reservoirs — adapts well to impounded water, which makes it common in the many dammed systems of the northeast.
Key Locations
- Salgado River basin, Ceará — the type locality for the species and a core part of its native range.
- Jaguaribe River basin, Ceará — one of the major northeastern drainages where piau verdadeiro is regularly caught.
- Rio Verde Grande, São Francisco basin — listed as a productive fishery for the species within the broader São Francisco drainage.
- Rio Paraopeba, Minas Gerais — a São Francisco tributary where the species has been documented migrating through fish ladders at the Igarapé Dam.
Specific Spots
- Near dam tailwaters and fish ladders, where migrating fish concentrate during the spawning run — the stretch immediately below a dam is often the most productive water.
- Along rocky or vegetated margins of reservoirs, where the fish graze on plant material and invertebrates attached to structure.
- Shallow, weedy coves and densely vegetated areas, which the species uses for spawning and as feeding grounds.
- Current breaks and slower pools in river stretches, especially where bottom substrate shifts from sand to rock or gravel.
Piau verdadeiro FAQ
Answers from onWater's species guide.
What are the best lures and bait for Piau verdadeiro?
Massa (homemade dough bait made from manioc flour, corn, or other plant-based ingredients) is the traditional and most widely used bait, local anglers often have their own recipes.
When is the best time to fish for Piau verdadeiro?
Rainy season (roughly November–April in the northeast) brings the best fishing as rising water triggers feeding and spawning movement. Dry season (May–October) concentrates fish in reservoirs and deeper pools, where they can still be caught but in tighter areas.
How do you catch Piau verdadeiro?
Most anglers fish from the bank or in small boats, presenting dough baits or natural baits on bottom rigs near vegetation, rocky margins, or dam tailwaters. Handline fishing remains common in the northeast, where the species is a familiar and accessible catch for local communities.
What do Piau verdadeiro eat?
Primarily plant material, algae, and aquatic invertebrates, its downward-angled mouth is built for grazing along the bottom and on submerged vegetation. Small dough baits, corn, and plant-based pastes mimic this feeding style well. Also takes small invertebrates and organic detritus.
Where do Piau verdadeiro live?
