Bonefish
Bonefish reach the southern edge of their western Atlantic range along Brazil's coastline, making them a rare but genuine target for saltwater fly anglers willing to explore the country's tropical flats.
They're not the centerpiece of Brazilian fishing the way they are in the Bahamas or Belize, but the fish are here — native, not introduced — and the same skills that work anywhere on the flats apply.
Scientific Name: Albula vulpes
Also known as Ubarana, peixe-osso
- Bright silver flanks with a bluish-green back; small, mirror-like scales that scatter light and make the fish nearly invisible over sand and turtle grass.
- Distinctly overhanging, pig-like snout with a downward-turned mouth positioned for rooting the bottom — the clearest field mark separating bonefish from other flat-dwelling silvers.
- Deeply forked tail and a single short-based dorsal fin set at mid-body; no fin spines anywhere on the fish.
- Most fish run 2–5 lbs and 18–24 inches; anything pushing 10 lbs is exceptional anywhere in the western Atlantic range.
What to know
Habitat Distribution
- Native to Brazil — the country sits at the southern limit of the species' western Atlantic range, which runs from North Carolina through the Caribbean and down to Brazilian coastal waters.
- Lives on shallow inshore flats: sandy and muddy bottoms, mangrove lagoons, and estuaries, typically in 1–15 feet of water, though capable of going deeper.
- Tolerates brackish conditions and occasionally pushes into estuarine and even freshwater edges, but the core habitat is shallow marine flats near mangrove coastlines.
- Brazil's northeastern coast, with its warm tropical shallows and extensive mangrove systems, represents the most likely habitat within the country.
Key Locations
- Brazil's northeastern coast — the warm, shallow tropical flats and mangrove systems here represent the most suitable habitat within the country's range.
- Estuarine and mangrove-fringed coastlines of the north and northeast, where soft-bottom shallows and tidal movement concentrate feeding fish.
Specific Spots
- Tailing fish on sandy flats at low tide — when bonefish tip nose-down to root the bottom, their tails break the surface and give away their position.
- Edges of mangrove roots and channels, where fish move in on the flood tide to feed and retreat to deeper water as the tide drops.
- Sand and grass flat transitions, where bonefish cruise the boundary between bare sand and vegetation looking for crabs and shrimp.
- Shallow estuarine mouths on an incoming tide — bonefish follow the water in, so position yourself ahead of the tide's leading edge.
Bonefish FAQ
Answers from onWater's species guide.
What are the best lures and bait for Bonefish?
Small jigs (1/8 to 1/4 oz) tipped with a piece of shrimp or a soft-plastic shrimp tail, cast ahead of a moving fish and let it sink to the bottom, then twitch slowly.
What flies work for Bonefish?
Shrimp patterns are the backbone of bonefish fly fishing, the Gotcha, Crazy Charlie, and Bonefish Scampi all imitate small shrimp and are cast ahead of moving fish, allowed to sink, then stripped slowly to imitate a fleeing or burrowing shrimp.
When is the best time to fish for Bonefish?
Calmer, drier months along the northeastern coast, roughly July through December, generally offer better flat visibility and more stable conditions for sight fishing. Tidal movement matters more than season on any given day; plan fishing around incoming and outgoing tides rather than time of year alone.
How do you catch Bonefish?
Bonefishing in Brazil follows the same approach used throughout the Caribbean: wade or pole a shallow flat on a moving tide, spot fish before casting, and present a fly or lure well ahead of the fish's path.
What do Bonefish eat?
Crabs, shrimp, clams, worms, and small mollusks dug from sandy or muddy bottoms, they root with that downturned snout and crush hard-shelled prey with grinding teeth in the throat. Small crab and shrimp imitations like a Merkin Crab or Gotcha (a shrimp pattern) match this feeding behavior directly.
