Rio Marié is unique in Brazil, with more than 500 miles of exclusive access to the only catch-and-release, "fly fishing only" river in a part of the world where rivers are often shared by half a dozen fishing operations.

This river area is huge, encompassing a truly vast amount of unspoilt water, boasting a healthy population of giant Peacock Bass. For anglers, this translates into very real opportunities to consistently hook and release much larger-than-average Peacock Bass on the fly.

Few, other than local natives, had ever explored the spiderweb of tributaries or investigated the labyrinth of oxbow lagoons that nurse this incredible fishery. Those who risked it all the first season came home to tell fish stories about huge Peacock Bass that are hard to fathom. We are just beginning to scratch the surface of what the Rio Marié has to offer, and already realise the Rio Marié is the ultimate trophy Peacock Bass fishery. Even the locals call it "Rio de Gigantes!"

During each fishing week, a serious angler is bound to hook into a good number of Temensis peacock bass whose average size is astounding at over 10 lbs, not to mention a significant amount of 20+pound trophies. Every day fly anglers are casting in the Rio Marie they are in the legitimate pursuit of the next world record Peacock.

And when anglers are happy with their double digits for the day and want to go lighter, be prepared for dozens of 3 to 8 pound butterfly peacocks which are extremely strong and great sport on 7 weight rods and poppers.
