Rio Marié Fishing Report – Week 1, August 10 to 17
We opened our 11th season with the energy this river demands. Rio Marié remains the ultimate, limited-access destination for giant peacock bass—a place designed for anglers who value refined tactics, disciplined casting, and the pursuit of exceptional fish. It is not for everyone. It is for those seeking the pinnacle of jungle fly fishing, where a single strike can define your week.
This week confirmed once again why the Marié holds the world’s largest specimens, and why its reputation is built on precision, persistence, and rarity.
This week also marked a special milestone: Carlos and Joaquim, once native guides, stepped up as the main professional fly-fishing guides of the Rio Marié. They are the very first indigenous guides to become full pro fly-fishing guides in the Amazon.
Fully trained through Untamed’s programme, they distinguished themselves with commitment, skill, and enthusiasm — even dedicating themselves to learning English to better connect with international anglers. Their achievement is a proud chapter in the story of the Marié, showing how deep local knowledge, combined with training and passion, elevates the entire experience.
Juliano’s mission was to land the biggest peacock bass of his life. In a quiet lagoon, his guide Rafael called out a cruiser. One precise cast with the Marié SLT, one decisive eat, and the fight was on. Juliano held firm and brought a 90cm giant to hand—textbook jungle execution.
With years of experience on these waters, Mike’s measured approach was rewarded with an 88cm, 22 lb trophy. A reminder that calm precision is the edge on the Marié.
Mike’s highlight came when casting to what seemed like a log. A heavy strip, and the log came alive. The flight ended with a 20lb temensis, a classic Marié deception and drama.
Using a fly tied by his grandfather, John, Matthew landed the biggest peacock bass of his young life. A generational moment, written on the waters of the Marié.
With water levels steady and bait becoming more concentrated in the lagoons, the weeks ahead promise consistent trophy opportunities. The Marié is set to deliver what only it can: precise casts, bigger fish, and the kind of encounters that define a lifetime of angling.
