Rio Marié Fishing Report – Week 9, OCTOBER 5 TO 12

The 2025 season on the Marié keeps proving its strength week after week. Excellent weather and ideal water levels combined to create one of the most productive fishing stretches so far, rewarding persistence, precision, and skill.

Returning friends and seasoned anglers made the most of every opportunity, with multiple fish over 20 lbs and a remarkable number of 21 peacocks exceeding 80 cm. Each day brought moments of power, challenge, and celebration — the essence of what defines fishing on the Marié.

No stranger to these waters, Matt joined CEO Rodrigo Salles and Rafael for a day that would become one for the books. Together they landed ten big fish, capped by Matt’s 90cm – 23.5 lb giant — the 11th fish over 90cm of the 2025 season and Matt Harris’ largest peacock bass to date. A fitting moment for an angler who has shared Marié’s story with the world for nearly a decade.

Rio Marié Fishing Report – Week 8, September 28 to October 5

The momentum on the Marié shows no sign of slowing down — it’s pure fire.

This week pushed the river into legendary territory, with over one hundred peacock bass surpassing the 80 cm mark in less than eight weeks. And that doesn’t even include the mythical 90 cm giants that continue to define the Marié as the ultimate big-fish destination on Earth.

With stable weather and flawless water levels, our group from the USA turned every stretch of river into an opportunity. From double hook-ups with 20-pounders to one of the largest fish of the entire season, this week was a masterclass in what the Marié stands for — precision, persistence, and the relentless pursuit of something extraordinary.

Known for her calm focus and unshakable connection to the water, Katie once again proved her skill on the Marié. In one of those moments when everything aligns, she landed a spectacular 88 cm, 23 lb peacock bass — the largest of the week and one of the standout fish of the 2025 season. Her catch was a reminder of why patience, timing, and trust in the guide make all the difference on the River of Giants.

Rio Marié Fishing Report – Week 7, September 21 to 28

Another unforgettable week came to an end on the Marié, marked by great camaraderie and remarkable fishing. We had the honour of hosting a group of long-time friends, joined by renowned bat conservationist Merlin Tuttle, who added to the spirit of exploration and appreciation for the Amazon.

The week’s defining moment was the landing of the 10th peacock bass over 90 cm of the 2025 season — an achievement unmatched anywhere else in the world of peacock bass fishing.

As water levels continued to drop, opportunities multiplied. The Marié once again proved why it stands alone as the River of Giants.

On the last day of his trip, Larry, who had already landed an impressive 18 lb fish earlier in the week — but the Marié had one more surprise in store. That afternoon, he spotted a powerful wake and placed his cast perfectly. The strike was instant and violent, peeling line and backing in seconds. The battle grew intense as the fish charged dangerously close to the bank’s structure, but Larry stayed calm and in control. Finally, a 21 lb giant slid into the net — the ultimate highlight of his week on the River of Giants.

Rio Marié Fishing Report – Week 6, September 14 to 21

This was a week of mobility and strategy, with the Untamed Amazon navigating to the upper reaches of the Marié in search of optimal conditions. Some days demanded persistence, but the reward came in the form of exceptional fish size and unforgettable moments.

Two fish over 90cm were landed — including a historic milestone for the Marié: the youngest angler ever to land a peacock bass of this size on fly gear. Even more special, both brothers shared this achievement in the same week — proving once again that the Marié is truly the River of Giants.

Matt joined his father and brother for a family adventure. After landing a solid 18lb fish, his guide spotted a massive peacock bass cruising nearby. Matt made the perfect cast — the fish ate instantly — and an intense fight followed, testing his strength and composure. When the battle was over, the giant measured 90cm, making Matt, at just 18 years old, the youngest angler ever to land such a trophy at the Rio Marié.

Returning for his second season, Alex was rewarded with the fish of a lifetime. One afternoon, while fishing a remote lagoon, his guide pointed out a wake moving along the edge. Alex’s cast landed precisely where it needed to, and the strike was explosive.
The fight was powerful and nerve-wracking, but Alex kept calm and used every bit of experience he had gained. The result: a 92cm, 26lb peacock bass — the largest fish of the season so far, one of the largest ever landed at the Marié. A moment his family — and our team — will never forget.

Rio Marié Fishing Report – Week 5, September 7 to 14

This was one of the most epic weeks we’ve ever had on the Marié. Every angler in the group landed fish over 80cm, and two of them surpassed the 90cm mark — a testament to the river’s unmatched reputation as the home of the world’s largest peacock bass.
The perfect mix of dropping waters and relentless pursuit turned the river into a stage for explosive encounters — line-screaming battles, personal milestones, and moments that embodied the very spirit of the River of Giants.

Known worldwide for his research on sharks, Michael came face to face with the Amazon’s apex predator. The encounter ended with a monster in the net — a massive peacock bass of a lifetime 25lb and 90cm that perfectly embodied the raw power of the Marié.

Benjamin’s highlight began with action in a pacu feeding frenzy, but the highlight was still to come. After a heavy strike in the middle of a lagoon, his line screamed into the backing. The battle ended in triumph — a 90cm, 24lb trophy and a memory that will last forever.

After days of searching, Will’s persistence paid off in a dramatic scenario. Just before a storm swept in, and with his friends cheering him on, he finally landed his long-awaited 20lb giant — seconds before racing for cover.

Rio Marié Fishing Report – Week 4, August 31 to September 7

This week brought a remarkable combination of experiences, as part of the group travelled to the Turi River—the Marié’s largest tributary—for the first headwaters camp adventure of the season. There, anglers were rewarded with untouched lagoons, wild landscapes, and encounters with giants.

Meanwhile, those fishing from the mothership found equally memorable action. Dropping water levels made fish more accessible, setting the incredible stage for 11 trophies over 20lb and several peacocks beyond 80cm.

The results spoke for themselves: a week full of powerful fish, dramatic battles, and stories that perfectly capture the River of Giants.

Hannes began his week with solid catches, but the river had saved something special for the end. On the very last day, guided by Sérgio, he spotted a faint ripple in the middle of a lagoon. One precise cast, one brutal strike — and suddenly his fly was gone in an explosion of water. Moments later, a 20lb peacock bass was in the net, the perfect closing chapter to his journey.

Gary’s week became a true saga of the Marié. While fishing a sandbar with his guide Agu, he intercepted a moving wake and brought a powerful 21lb peacock bass to hand. The following day, persistence turned into glory: with guide Rafael, he connected with the fish of a lifetime — a 90cm, 23lb giant that stripped line into the backing before finally surrendering. And the river was not finished with him. Later that same afternoon, Gary landed yet another 21lb trophy, sealing a run that few anglers will ever experience.

Matt had already landed a 20lb fish that morning, but destiny had more in store. In an unnamed lagoon on the Turi River, his guide challenged him: land a giant here, and the place would forever carry his name. At first, the water seemed quiet — until a sudden strike sent a massive fish charging into timber. A native guide dove into the water, wrestling alongside Matt for more than 30 minutes until they finally brought the fish clear. The reward: a 21lb peacock bass and the honour of naming a new lagoon of the Marié.

Alex had already secured a strong 20lb fish, but what followed was nothing short of epic. At the mouth of a lagoon, his fly was devoured by a monster that tore downstream with unstoppable force. Instinctively, Alex and his guide leapt from the boat onto a sandbar, bracing against the charge. The fish ripped through the fly line and into the backing, nearly breaking free. At that critical moment, another boat approached, and a native guide dove into the current, swimming more than 100 feet to seize the line by hand. Against all odds, they subdued a 21lb peacock bass — a capture as dramatic as the Marié itself.

Rio Marié Fishing Report – Week 2, August 17 to 24

This week’s group arrived eager to embrace everything the Marié offers. Their energy and enthusiasm set the tone both on the water and aboard the Untamed mothership, creating a week filled with camaraderie, laughter, and memorable encounters.

The fishing matched the spirit of the group. With water levels steady and dropping, anglers connected with powerful peacock bass across lagoons and structures, testing skill and persistence against some of the river’s largest residents. Giants over 20lb made their presence known, proving once again why the Marié is called the River of Giants.
It was a week that blended technical challenge with pure enjoyment—a reminder that at the Marié, success is measured not only in numbers, but also in the stories shared and friendships forged along the way.

Among highlights this week was Brad, when what began as a slow day turned into a story for the ages. After a fly change, Brad hooked into a true monster—a 90cm, 24lb peacock bass so powerful it broke the first landing net. With the backup net, they finally secured the fish, sealing an unforgettable triumph.

Then on the final day, David was still searching for his trophy. Persistence paid off after countless casts, and he finally connected with an 88cm, 22lb giant. The fight was tense, the reward immense—a perfect finale to his week on the Marié.

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.
