Pacú (Colossoma macropomum and Piaractus spp.) are powerful, hard-fighting freshwater fish, often referred to as the “vegetarian piranha” due to their similar appearance but distinct feeding habits. Found in South America’s tropical rivers and flooded forests, pacú are known for their strong, bulldog-like fights, unique human-like teeth, and ability to crush nuts and fruits. These fascinating fish provide an exciting challenge for light tackle and fly anglers alike.
Where to Find Pacú
Pacú thrive in slow-moving rivers, flooded forests, and oxbow lakes, often feeding near fruiting trees, submerged logs, and riverbanks. The top destinations for pacú fishing include:
- Brazil (Amazon Basin & Pantanal) – Prime waters for giant Tambaqui (Black Pacú).
- Bolivia (Secure, Pluma & Mamoré Rivers) – Jungle fly fishing for pacú, a bucket-list experience.
- Peru & Colombia (Amazon Tributaries) – Strong populations of multiple pacú species in remote waters.
- Argentina & Paraguay (Paraná River & Iberá Wetlands) – Excellent fishing for Piaractus pacú near submerged structure.
- Venezuela & Guyana – Remote jungle rivers with untouched populations of large pacú.
What Makes Pacú Special?
Pacú are unlike most freshwater game fish, as they feed primarily on fruits, seeds, and nuts that fall from overhanging trees. They have incredibly strong jaws and molar-like teeth, capable of crushing hard shells and vegetation. Their unexpected power, rapid bursts of speed, and ability to break leaders make them a formidable opponent for any angler.
Top Fishing Techniques
Since pacú primarily feed on vegetation and fallen fruits, targeting them requires unique tactics. Some of the most effective methods include:
- Fly Fishing with Fruit & Nut Imitations – A specialized and exciting way to target feeding pacú.
- Floating Baits (Berries, Bread, Corn, Nuts) – Drifted near tree lines where pacú actively feed.
- Casting Soft Plastics & Small Lures – Occasionally effective when pacú are feeding on small fish or insects.
- Live & Cut Bait Fishing – In some areas, pacú will take worms or shrimp fished near structure.
- Chumming with Fruit or Corn – Used to attract pacú in slow-moving water.
Best Time to Fish for Pacú
- Brazil & The Amazon Basin – Best from June to November, when water levels drop.
- Bolivia & Peru (Jungle Rivers) – Best from August to November, during dry season.
- Argentina & Paraguay – Best from spring through early fall, when fish are most active.
- Venezuela & Guyana – Best from September to March, when fruiting trees attract feeding fish.
