- BigJoe's tip
Arowana jump wildly when hooked. Keep the line tight and the rod low.
- 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
Good eating when fresh.
- Cleaning
Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.
- Cooking suggestions
Eaten locally, but sport anglers release them.
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 rules; arowana are protected during spawning season in some areas. 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.
