Jungle Gold: Fly Fishing for Peacock Bass at Rio Maria
When two seasoned anglers, James Norris and Jim Curry, team up the result is a blend of hard-earned knowledge and unfiltered passion for the sport of fly fishing. Between them, they have chased fish across the globe, from chalk streams to saltwater flats. But few destinations have left as deep a mark as the Rio Maria, a remote and electrifying corner of the Brazilian Amazon.
There are places that seem lifted straight from an angler’s dream: wild, unspoilt frontiers where the jungle thrums with life and the fish strike with explosive power. Fly fishing in the Amazon, particularly on the fabled Rio Maria, is not just an adventure. It is a complete immersion into nature at its most untamed.
Welcome to the Jungle
Reaching Rio Maria is no casual outing. This isn’t a ‘pop down to Penrith after work’ kind of trip. It’s a full-throttle expedition into the Brazilian Amazon: an adventure that starts with multiple flights and ends with a floatplane deep into a world untouched by time.
But when you finally arrive? Oh, it’s worth it. The jungle unfolds like a living cathedral with emerald green, teeming with energy. Howler monkeys roar from the treetops, macaws streak across the sky like fireworks, and the river pulses with potential. Beneath the dark, tea-coloured waters lies a creature of raw power and mythic status, the Peacock Bass.
The Beast Beneath
Calling the Peacock Bass aggressive is like calling a hurricane breezy. These apex predators don’t just strike, they obliterate. Hook one and brace yourself for a bare-knuckle brawl. They charge from beneath sunken trees, smash your fly with brutal force, and dive for cover before you can react. Every strike is an explosion, every battle a heart-pounding slugfest.
The heavyweight champ, Cichla temensis, regularly pushes past 20 pounds. Even the ‘average’ 10-pounders will shred your fly line, ruin your fishing tackle, and test every skill you've ever honed. Their colours are breathtaking, electric green, molten gold, and warpaint stripes that blaze under the Amazon sun. They’re living treasure, and they fight like jungle demons.
Arm Yourself
This is no place for finesse. This is combat fly fishing. Bring fly fishing rods with backbone and attitude. A single-handed 8 or 9-weight is your sword, paired with a saltwater reel featuring bulletproof drag. Think warm-water floating and intermediate lines, cold water lines turn gummy in the Amazon heat. Don’t forget the leaders: heavy-duty 40 to 60 lb fluorocarbon will save your fly.
Topwater flies are where the real thrill lies. Pole Dancers, oversized Poppers, and Crease Flies that gurgle and chug until, boom, the water detonates. Subsurface patterns like Game Changers, Deceivers, and flashy firetiger streamers bring beasts out of the deep.
The Thrill of the Chase
Fly fishing Rio Maria is something else. You’ll experience blow-ups before breakfast, doubles before lunch, and drag-screaming chaos in the afternoon heat. The local guides are exceptional, born of the river, jungle-savvy, and dialled into every nuance of water, current, and structure.
But the real reward is in the moments. The jungle falling silent before a storm. A violent topwater strike mere feet from your skiff. Watching your fly disappear in a spray of chaos while pink dolphins breach in the distance. Parrots wheel overhead as golden light filters through the trees. Every cast, every strip, every breath, it all feels electric.
More Than a Trip: A Transformation
Fly fishing at Rio Maria isn’t just a trip it’s a rite of passage. It strips away pretence and replaces it with adrenaline and awe. Your skills are tested, your kit pushed to breaking point, and your love of the sport reignited.
You’ll return home changed: sun-scorched, bruised, and buzzing. And when you next tie a fly on your favourite stretch of river in the Lake District, you’ll smile knowing that deep in the Amazon, gold still swims in the shadows, waiting for you.
Fishing Season- When to Go
The prime season for fly fishing the Rio Maria is from late August through early February. This is the Amazon’s dry season: water levels drop, lagoons become accessible, and the Rio Negro Basin comes alive. Thanks to its unique geography, Rio Maria remains one of the most consistent and productive fisheries in the entire Amazon.
Tackle Tips for Fly Fishing Rio Maria
Fly Fishing Rods
Bring two single-handed rods in the seven to nine-weight range. One should be ready as a backup, already rigged. Saltwater rods with strong butt sections are ideal — the same types used for bonefish or baby tarpon.

Reels and Lines
Use saltwater reels with dependable drag systems. These fish hit hard. At least 30-pound backing is essential. Use warm-water weight-forward lines. Cold-water lines go soft in the heat. Carry a spare — especially an intermediate tip line.
