Rio Marie Fly Fishing

On August 25, 2022, Rodrigo M. Salles was fly fishing the Rio Marié. On his very first cast of the day, he hooked and landed a 92 centimeter 25.3-pound peacock bass. With this fish, Rodrigo tied the IGFA All-Tackle Length World Record for the species.

Fly Fishing the Rio Marie

The Rio Marie is a very remote river—more than 400 miles by floatplane from Manaus, Brazil. The Marie River begins on the northwest side of the Brazilian Amazon, near the Colombian border, and is a tributary of the upper Negro River. The river is contained inside an Indian territory of more than 494 million acres.
The Rio Marie liveaboard adventure is the first official sportfishing operation inside Indian territory in Brazil. It is now the largest area in the world specifically dedicated to fly-fishing-only and catch-and-release-only.There are over 400 miles of river, tributaries, and lagoons.
The Temensis peacock bass, the largest of all peacock bass, average 10-to 18-pounds in the more remote locations but have been known to reach 30-pounds. In 2016, a 28 ½-pound fly-caught peacock bass was landed at the Rio Marie, and in 2017, a near 31-pounder! (It was disqualified as an IGFA world record due to some technical issues.) The butterfly peacock bass are abundant and smaller, reaching up to 13-pounds.
Season:  The Fly-Fishing-Only season runs from August to mid-December—during the dry season when the water levels are at their lowest.

The Mobility of the Untamed Amazon – the deluxe, shallow-draft mothership – When the water is high, they fish the headwaters of Marié further upriver, exploring new tributaries and lagoons. Upstream, there is 100 more miles of river to explore. When the water drops, they move downstream to familiar beats. Not only does this mobility allow them to fish and explore new water, but it also helps to manage fishing pressure on the river by incorporating a beat system across a broad expanse of over 200 river miles.

Rio Marie Liveaboard

The Untamed Amazon has three levels. The lower floor is a restricted area for staff only and includes the inner workings of the vessel with twin 200-HP propulsion engines. The main floor has eight guest suites, accommodating up to 18 guests. The top floor is the spacious living and dining room, plus an open lounge where beverages are served.

Getting to the Liveaboard:
It is best to arrive in Manaus a day early (on Friday night) rather than late on Saturday night. At the international airport in Manaus, you'll be greeted by an English-speaking representative. He'll arrange for transfers to a boutique hotel in Manaus. You and another angler will share a double occupancy room included in the package. After an early breakfast at the hotel, the driver will pick up your group between 5:30 and 6:30 a.m. and head to the local airport. You'll take a 3.5-hour private charter flight on a Cessna Caravan hydroplane to where the liveaboard is anchored and waiting for you. (The ground transfers, the first hotel night in Manaus, and the roundtrip hydroplane flight are included in the package.) On the liveaboard, you'll have a light lunch, followed by a short orientation. There will be no fishing on the day of arrival. You'll have a chance to get situated and prepare tackle.
Departure Day:  After breakfast, you'll have a couple of hours to relax before the hydroplane flight back to Manaus. Depending on your departure time, you can fly home on the same day or spend another night in Manaus. (Final hotel night is not included in the package.

The Project has a significant user fee on all visiting anglers.

Rio Marie High Water Policy:

Fishing for peacock bass in the Amazon jungle represents one of the last frontiers in the fly-fishing world. As with any such hyper-remote destinations, there can be challenges associated with offering a first-class experience in the ‘back of beyond.’ In the Amazon, water level conditions will, on occasion, present such challenges. The Amazon River annual water level cycles are not a simple equation, even for the most experienced local experts. Normally, high and low water levels here follow a fairly predictable monthly cycle, but climate changes and the effects of stronger or weaker El Niño and La Niña cycles can directly and immediately affect those levels. Specifically, these El Niño and La Niña events tend to impact the amount of rain in the headwaters of Amazon rivers, which in turn affects the entire Amazon basin. Water levels are important when fishing for peacock bass, and understanding how to work around them is a key component to success. Low water does not always result in the best fishing, just as high water is not always the worst thing. More important is to understand where and how to fish as the water fluctuates.
The Rio Marie system has several hundred miles of rivers, tributaries, and lagoons from its headwaters down to its merging with the Rio Negro. Within this extensive water system, the liveaboard can move up or downstream throughout the season—every week or even daily—to reach the best water levels for trophy fish. This system is useful when navigating less than ideal water conditions. Although the Rio Marie’s season is based on the best water conditions, it’s difficult to predict water levels, and this is one of the risks associated with fishing the Amazon. If you are not comfortable with the risk of the river levels being too high or low during your trip, then it is probably not the trip for you. You will not be refunded for water conditions that may not meet your expectations. In the event the water is too high to fish on any given week, your week will be rescheduled to a later time, but there will not be a refund of your trip payment.
