Keep an eye on this page for the Rio Marié 2026/2027 fishing reports which include highlights and statistics from the season. This incredible fishery in the Brazilian Amazon comprises more than 500 miles of exclusive access to the country’s only catch-and-release, “fly fishing only” river. With more than 15 species of peacock bass, regular encounters with fish over ten pounds and a realistic change of a trophy peacock bass of 20lb, the Rio Marié is a great choice for some exciting fishing. We will update the page with all the weekly news from the guides on the ground.
Rio Marié Fishing Report – Week 6 – September 13th to 20th
The sixth week of the season brought another shift to the Rio Marié as water levels slowly began to rise. Fishing demanded consistency all week, with tougher stretches requiring anglers and guides to stay focused and keep adjusting their approach.
Several returning friends of the Rio Marié joined the group, bringing experience with this fishery into conditions that didn’t always make opportunities easy to find. The week’s rhythm required commitment, but persistence eventually opened the door to meaningful encounters.
By the end of the week, the group had created a collection of very different stories. Some were defined by consistent trophy-class fish, others by the remarkable colors that make peacock bass so distinctive, and one experience brought two generations of the same family together on the water.
Fishing Stats:
Total Peacock Bass Caught: 576
Temensis >10lb: 7
Temensis >15lb: 4

This week’s highlights
In a week when fishing demanded consistency, Thiago found his opportunities and made them count.
He landed not one, but two 21lb peacock bass during the same week, an impressive result under demanding conditions.
Finding one fish of that class can define a trip. Repeating the feat in the same week showed the consistency required to capitalize when the right opportunities finally appeared.
Not every memorable peacock bass is defined only by its measurements.
Warren landed one of the most strikingly coloured peacock bass seen on the Rio Marié. The vivid colouration immediately set the fish apart and made it one of the week’s visual highlights.
It was another reminder that these fish’s appeal extends beyond size alone. Their patterns, colours, and individual characteristics make every encounter different.
At 89, Kyoshi Suguita kept adding new experiences to a lifetime of fishing.
During a challenging week, he remained engaged in the pursuit and successfully brought a large peacock bass to the boat. His presence on the Rio Marié showed that decades of experience and a continued commitment to fishing can still lead to meaningful moments on the water.
Fishing alongside his father Kyoshi, André added another chapter to the family’s week with an 85cm peacock bass, his largest fish of the trip.
With father and son sharing the same boat, both had meaningful catches during the week. Their experience brought a different dimension to the fishing, connecting two generations through the same pursuit on the Rio Marié.
As the river rises slowly, changing water levels will continue to shape fishing in the days ahead.
Our guides will keep evaluating how the river develops and adjusting their approach as new conditions emerge. Week six reinforced the importance of consistency, observation, and readiness when pursuing trophy-class peacock bass on the Rio Marié.
Rio Marié Fishing Report – Week 5 – September 6th to 13th
The Rio Marié entered its fifth week with a rapidly changing river and another opportunity to demonstrate what makes this fishery so remarkable. As water levels dropped, navigating the river became increasingly demanding, requiring guides to constantly reassess their routes and adapt to the conditions.
The fifth week of the season brought a new group of anglers into this dynamic environment. The week unfolded with consistent opportunities for quality peacock bass and several moments that would leave their mark on the 2026 season.
What followed was an exceptional collection of trophy catches, including a remarkable simultaneous encounter and a new season benchmark. Each moment reflected a different aspect of fishing the Rio Marié, where observation, precise decisions, and the ability to react can turn a single opportunity into something memorable.
Unforgettable moments
Sometimes, the difference between an opportunity and a missed fish comes down to a decision made in a fraction of a second.
Michael spotted movement in the water and immediately delivered his streamer toward it. Before the fish had fully revealed itself, a powerful peacock bass erupted at the surface, took the fly, and began stripping line.
His quick reaction had connected him with a beautiful 20lb peacock bass.
It was a moment that demonstrated the importance of observation and instinct on the Rio Marié. Recognizing an opportunity and responding without hesitation can make all the difference when pursuing trophy class fish.
Few moments capture the excitement of fishing the Rio Marié quite like two anglers connecting with exceptional fish at precisely the same time.
While wading along the river’s margins, Ken and Richard experienced a remarkable simultaneous hookup. Both anglers connected with giant peacock bass, and both successfully landed their fish.
Two 21lb peacock bass, hooked and landed side by side.
Landing a fish of that caliber while wading is already a significant achievement. Experiencing two such catches simultaneously made this encounter one of the defining stories of the week.
For Ken and Richard, it was a shared moment that demonstrated just how remarkable an opportunity on the Rio Marié can become.
The fifth week still had another major achievement to deliver.
Fishing alongside his guide Rafael, Van connected with an exceptional peacock bass that would establish a new length benchmark for the 2026 season.
After landing the fish, the measurements confirmed its significance: 92cm and 24lb, the longest peacock bass recorded so far this season.
Crossing the 90 cm mark represents a major achievement on the Rio Marié, and Van’s catch raised the season’s length benchmark to an exceptional 92 cm.
The result added another meaningful chapter to the opening weeks of 2026 and reinforced the remarkable trophy potential of this protected fishery.

Rio Marié Fishing Report – Week 4 – August 30th to September 6th
High water changes the way the Rio Marié must be approached. When fish spread across a much larger environment, familiar patterns become less predictable and every decision on the water becomes more important.
This week we welcomed the Tailwaters group, a lively and energetic crew that embraced the experience from the beginning. Throughout the week, anglers and guides remained committed to the process, working together and making the most of every opportunity the river presented.
Weeks like this reinforce an essential part of trophy peacock bass fishing in the Amazon. Success is not built around waiting for perfect conditions. It comes from consistency, careful decisions, teamwork, and being ready when the right opportunity finally appears.
Unforgettable moments
With the river still running high and fish scattered throughout the flooded margins, finding a trophy class peacock bass was especially challenging.
Robert made his opportunity count.
He connected with an exceptional 88cm, 20lb peacock bass, a remarkable fish under conditions that made encounters with larger temensis harder to come by.
The catch reflected exactly what the week demanded. Stay focused, keep fishing consistently, and be prepared when the river finally presents the opportunity you have been searching for.
With water levels beginning to drop by the end of the week, the Rio Marié is entering another transition.
The changing river will continue to influence fish location and behavior, requiring our guides to observe each new development closely and adjust the strategy accordingly. As conditions evolve, every new stretch of water can create another opportunity in the pursuit of trophy class peacock bass.
Fishing Stats:
Total peacock bass Caught: 476
Temensis over 10lbs: 3
Temensis over 15lbs: 1
Temensis over 20lbs: 1
Temensis over 80cm: 2
Rio Marié Fishing Report – Week 3 – August 23rd to 30th
Week three brought a different challenge to the Rio Marié. With water levels continuing to rise, fish became more scattered and increasingly difficult to pattern, demanding constant adjustments from anglers and guides throughout the week. Hosted by longtime friend Matt, the group relied on experience, consistency, and careful reading of the river to keep creating opportunities.
Instead of waiting for conditions to become easier, the boats adapted day by day, focusing on edges and structure and making every opportunity count. And during a week when each encounter carried extra weight, one explosive surface take delivered exactly the kind of moment that reminds us why topwater fishing for trophy peacock bass is so memorable.
Unforgettable moments
During a week when fish were more scattered and every opportunity carried extra importance, Matt produced a moment that captured the excitement of topwater fishing on the Rio Marié.
Working the surface with one of his favourite peacock bass flies, the Pole Dancer, Matt drew an explosive strike from an 85cm temensis. The fish attacked directly on the surface, creating the kind of visual encounter that makes topwater fishing so compelling.
For an experienced Rio Marié angler hosting his own group through a challenging week, it was a fitting moment. A well placed fly, an aggressive surface take, and a trophy class fish that rewarded the continued search.
Fishing stats:
Total peacock bass caught – 278
Fish over 10lb – 2
Fish over 15lb – 2
Fish over 80cm – 1
Rio Marié Fishing Report – Week 2 – August 16th to 23rd
In the Amazon, giant peacock bass are rarely the result of luck alone. They are earned through persistence, consistency, teamwork, and the ability to adapt—and the second week of the 2026 Rio Marié season proved exactly that.
Week two also opened a new chapter with the first Headwaters Camp expedition of the season. Part of the group traveled into the upper reaches of the Rio Marié, while the remaining anglers continued exploring the main river from Untamed Amazon.
The river rose steadily throughout the week, constantly reshaping the fishing conditions and demanding careful decisions from our entire team. Movement became the name of the game. Taking full advantage of the mobility of Untamed Amazon, we repositioned the mothership, explored different stretches of the river, and kept our anglers close to the areas where the best opportunities were developing.
The contrast between the Headwaters Camp and the main river created two distinct experiences unfolding simultaneously across the Marié. Yet both groups shared the same essential approach: remain focused, fish consistently, and adapt to every change the river presented.
Even under challenging conditions, that strategy produced exceptional results: three peacock bass over 20lb, ten fish measuring more than 80cm, and the first 90cm fish of the season—a spectacular 24.5lb giant.
These results demonstrate what makes Rio Marié so extraordinary: the long-term protection of an immense and pristine watershed, the deep knowledge and dedication of our Indigenous and professional guides, and an operation designed to move with the river instead of simply waiting for conditions to improve.
Unforgettable moments
Some fishing days require hours of searching before the right opportunity appears. Others change almost immediately.
Less than five minutes after he began fishing one morning, Joe connected with an enormous peacock bass. It was his first fish of the day—and one of the defining catches of the entire week.
After a powerful fight, Joe landed an impressive 85cm, 20lb temensis. Catching a fish of that calibre is always remarkable, but encountering one within the opening minutes of the session made the moment unforgettable.
It was a perfect example of what the Rio Marié can deliver at any moment. Every cast matters, every opportunity must be taken, and persistence must always be matched by readiness.
One of the week’s most exciting moments was sight-fishing to a true giant holding near the surface. After the fish repeatedly refused larger flies, we noticed it was chasing much smaller baitfish and changed to a pattern that matched their size.
The adjustment worked immediately. The fish attacked on the first cast, took the line deep into the backing, and raced toward the structure. After an intense fight, we landed the first 90cm peacock bass of the season—a spectacular 24.5lb temensis.
A perfect example of how observation, adaptation, and precise decisions can turn an opportunity into the fish of a lifetime.
As the river continues to rise, the coming days will demand even greater attention to how conditions develop throughout the main river and the headwaters.
Week two reinforced a fundamental truth about fishing in the Amazon: conditions may change quickly, but persistence, consistency, teamwork, and intelligent movement create opportunities. On the Rio Marié, any one of those opportunities can become the fish of a lifetime.
Fishing stats:
Total peacock bass caught – 616
Fish over 10lb – 7
Fish over 15lb – 8
Fish over 20lb – 3

Rio Marié Fishing Report – Week 1 – August 9th to 16th
The 2026 season began with a group of Brazilian anglers, several of them longtime Rio Marié veterans returning once again to pursue the giant peacock bass that define this fishery.
From the opening days, their experience on these waters shaped the rhythm of the week. Familiarity with the fishery, careful reading of the river, and consistent execution created a strong start to the new season.
With mostly sunny conditions and water levels beginning to drop toward the end of the week, the Rio Marié offered a dynamic opening chapter and set the tone for the weeks ahead.
Unforgettable moments:
Eric is a true Rio Marié veteran, with years of casts and stories accumulated on these waters. Yet this opening week gave him something he had never experienced before.
In clear water, Eric spotted a giant peacock bass guarding its nest and had the opportunity to sight cast to the fish. He placed the fly in its path, watched the fish turn and eat, and stayed connected through the run.
The result was his first ever sight casted 20lb peacock bass, a new milestone even after many seasons on the Marié and a catch that added another chapter to his history with the river.
Earlier in the week, Helton had an opportunity at a true giant but watched the fish slip away. Rather than allowing that moment to define his trip, he remained focused and continued working the water.
His second opportunity came on the afternoon of the final day. This time he connected and landed a beautiful 20 lb peacock bass, closing his week with one of the fish he had come to the Rio Marié to find.
After an opening opportunity was lost, finishing the trip with a fish of that class made the final afternoon especially meaningful.
Fishing stats:
Total peacock bass caught – 701
Fish over 10lb – 6
Fish over 15lb – 12
Fish over 20lb – 3
Fish over 80cm – 10
