About Rio Arinos
As a river in Mato Grosso, Brazil, Rio Arinos fishes best when the flow is steady and the water is clear enough to see a foot or two down. Anglers who do well at Rio Arinos pay attention to small things: the angle of the current, the colour of the water, what's hatching, where the wading birds are working. Fly anglers can match local insect activity; spin anglers can run small spinners or soft plastics through the same lies.

Fishing Techniques
- For Vampire fish
Use a wire leader to prevent bite-offs, as vampire fish have extremely sharp teeth.
- For Piavuçu
Fish near submerged structure like fallen trees or weed beds, as Piavuçu often ambush prey from cover. Vary your retrieve speed to find what triggers a strike.
- For Giant trahira
Fish near structure such as submerged logs, rocks, and vegetation, as Giant Trahira are ambush predators.
