Fast rapids and the eddies below them in the Amazon, Orinoco and Guiana rivers.
- Depth
5–30 ft in fast water.

Early morning and late afternoon.

Heavy jigs, deep-diving crankbaits and spoons on wire leaders.

Catch it
Step by step, from first cast to landing.
Step-by-step: how to catch it
- Go where it lives: Fast rapids and the eddies below them in the Amazon, Orinoco and Guiana rivers.
- Rig up: 7 ft medium-heavy baitcasting or spinning rod; 8–9 weight fly rod. Wire or 60–80 lb fluorocarbon for toothy fish.
- Pick your bait: Cut fish and live baitfish. Lures: Heavy jigs, deep-diving crankbaits and spoons on wire leaders.
- Fish it: Cast jigs or crankbaits into the eddies and current seams below rapids and let them sink. Payara hit hard and jump.
- Time it: Early morning and late afternoon. No tide — falling water after the rainy season is best.
- Fishing techniques
Cast jigs or crankbaits into the eddies and current seams below rapids and let them sink. Payara hit hard and jump.
- BigJoe's tip
Their bony mouth makes hook sets tough. Use very sharp single hooks and expect to lose a few.
- Catch and release
Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.
Clean & cook
Is it good to eat, and how to prepare it.
- Edibility
Edible but not prized — strong or bony; many anglers release it.
- Cleaning
Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.
- Cooking suggestions
Edible but bony; usually released.
Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
Sharp teeth on many river fish (dorado, payara, piranha, tararira) — use pliers and lip grips. Caimans, stingrays and strong currents are real hazards; shuffle your feet when wading.
- Regulations
Follow local river rules; most fishing is catch-and-release. Every country requires a fishing license (in Brazil, the Licença de Pesca Amadora), each Argentine province and Brazilian state adds its own rules, and most rivers close during the spawning season. Indigenous lands and strict reserves are closed to outside anglers without permits.
- Conservation
Keep only what you'll eat, release the rest quickly, and follow size and bag limits.
