Piranha

Piranhas are a fixture of Brazilian freshwater fishing, from the flooded forests of the Amazon and Rio Negro to the vast wetlands of the Pantanal. Locals fish them for the table as much as for sport, using simple tackle and raw meat.
Several species are present — including the large piraya and various Serrasalmus — and while the reputation precedes them, they're a practical, accessible target that rewards knowing where big fish concentrate.
Scientific Name: Serrasalmus eigenmanni
Also known as piranha, piraya, pirambeba
- Deep, laterally compressed body with a distinctive rounded or rhomboid profile; silvery to dark flanks, often with a reddish or orange belly in Pygocentrus piraya and related species.
- Razor-edged, interlocking triangular teeth are the clearest ID feature — handle with extreme care; even a fish that appears dead can bite.
- Serrasalmus species (pirambebas) tend toward a more elongated, darker body; S. manueli and S. gouldingi carry a prominent humeral spot (dark mark just behind the gill cover) in most life stages.
- Most fish run 20–35 cm; larger Serrasalmus species such as S. manueli and S. rhombeus can exceed 50 cm and are among the biggest in the family.
What to know
Habitat Distribution
- Native throughout Brazil — found in the Amazon basin, Rio Negro, Rio Solimões, Rio Tapajós, and the Pantanal wetlands of Mato Grosso do Sul.
- Occupy rivers, oxbow lakes, floodplain lakes, and seasonally flooded forest — the igapó and várzea habitats of the Amazon are core territory.
- During high water, schools move into flooded timber and treetops; as water drops, they concentrate in lakes, channels, and river margins.
- The Pantanal holds dense populations year-round, particularly in closed or slow-moving lakes where large predatory fish gather.
Key Locations
- Rio Negro and Anavilhanas Archipelago — blackwater flooded forest holds multiple Serrasalmus species; accessible from Manaus.
- Rio Solimões near Manaus — guided piranha fishing tours run regularly from the city into adjacent floodplain lakes.
- Santarém area, Maica Lake — floodplain lakes at the confluence of the Amazon and Rio Tapajós are productive and accessible to visiting anglers.
- Pantanal wetlands, Mato Grosso do Sul — dense populations in slow lakes and streams; local guides like those based near Corumbá know exactly where schools concentrate around larger predatory fish.
- Parintins — river town on the Amazon main stem with guide-led piranha fishing in surrounding floodplain channels.
Specific Spots
- Flooded treetops and submerged timber during high-water season — piranhas use the structure as cover and ambush points for smaller fish moving through.
- Oxbow lakes and floodplain pools cut off from the main river; restricted water movement concentrates fish and their prey together.
- Edges of schools of larger fish like pintado or pacu — piranhas follow big fish and feed on scraps, scales, and injured baitfish.
- Shaded banks and creek mouths in the Pantanal, especially where current slows and organic debris collects.
Piranha FAQ
Answers from onWater's species guide.
What are the best lures and bait for Piranha?
Raw red meat, beef heart, beef fat, or fresh fish chunks, is the universal bait used by local guides across the Amazon and Pantanal; it's cheap, effective, and what piranhas key on naturally.
When is the best time to fish for Piranha?
Dry season (roughly June–October in the Amazon, May–September in the Pantanal) concentrates fish in shrinking lakes and channels, the most productive time to find and catch piranhas consistently.
How do you catch Piranha?
Most piranha fishing in Brazil is done from small boats or canoes, drifting or anchoring over floodplain lakes, flooded timber, and slow channels. Guides slap the water surface to attract schools, then drop baited hooks to mid-column or near bottom.
What do Piranha eat?
Primarily eat smaller fish, fins, scales, and whole baitfish, but will also take chunks of meat, offal, and carrion; raw beef or fish scraps on a plain hook is the standard bait used by local guides across the Amazon and Pantanal.
Where do Piranha live?
Native throughout Brazil, found in the Amazon basin, Rio Negro, Rio Solimões, Rio Tapajós, and the Pantanal wetlands of Mato Grosso do Sul. Occupy rivers, oxbow lakes, floodplain lakes, and seasonally flooded forest, the igapó and várzea habitats of the Amazon are core territory.
