What it is.
A Rio Negro basin trip for speckled peacock bass, locally called tucunaré-açu. It differs from the butterfly peacock bass fishery in Florida. The exact tributary is an essential part of the destination, because one Amazon calendar does not describe every river.

Where to go.
Rio Negro basin, Amazonas. These destination profiles match the named water or departure base. Each retains its own research status.
The season, with context.
Low-water season; exact months differ across Rio Negro tributaries and remain unresolved here.
A seasonal pattern, a provider schedule, and a legal opening are different facts. Confirm the current rule for the exact water and trip category.
Official rules and permissions
How it is fished.
Cast large plugs, jigs, or streamers.
The research describes large plugs, jigs, and streamers from a river lodge or liveaboard format. Ask the operator to name the tributary and explain the current water-level plan. Low water is the documented context. The checked material does not settle one month range for the whole basin.
Planning format: Multi-day; river lodge or liveaboard. Confirm the actual duration with the provider.
What to bring.
- Sun and insect protection, rainwear, and quick-drying clothing.
- A soft bag within the confirmed boat or aircraft allowance.
- The operator’s target-specific tackle list, including compatible leaders and connections.
What a guide provides.
No provider inclusions are confirmed here. Use this trip-specific list to ask what the actual guide supplies. Mark an item “Guide provides” only after confirmation.
- Confirm the named tributary, local access authorization, and transfer route.
- Ask about boat, guide, tackle, meals, and remote communications.
- Agree on what changes if water levels prevent the planned fishing area.

What seasonal window does the evidence support?
