- Pick your bait: Whole or cut fish (2–10 lb baitfish for the big ones). Lures: Rarely; mostly a bait fish.

- BigJoe's tip
Fish the deepest hole below a big rapid or where two rivers meet.
- 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
Excellent eating — one of the best-tasting fish in its range.
- Cleaning
Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.
- Cooking suggestions
The young fish (filhote) are among the most prized eating fish in the Amazon — firm white steaks, grilled or stewed.
Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
A huge, heavy fish that can pull a person off a small boat — use a harness, and never wrap line around your hands.
- Regulations
Minimum sizes and closed seasons apply in Brazil; many lodges release all big fish. 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
Dams and overfishing threaten its long migrations.
