Traíra
The traíra is one of Brazil's most widespread freshwater predators, found from backyard açudes in the Northeast to Amazon jungle backwaters.
Anglers target it for its explosive topwater strikes and willingness to hit lures in water where other species won't bite. Both Hoplias curupira (Amazon basin) and H. brasiliensis (northeastern Brazil) are fished under the same name.
Scientific Name: Hoplias curupira
Also known as Traíra, Trahira, Dog Fish, Wolf Fish, Lobó
- Stout, cylindrical body with a large, flattened head and a mouth full of sharp, recurved teeth — unmistakable in hand and worth careful handling.
- Dark brown to olive-black ground coloration, often with faint darker banding or mottling along the flanks; pale, cream-colored belly.
- H. curupira distinguished by 34–39 lateral-line scales and a notably wide snout; H. brasiliensis endemic to northeastern Brazil within the same species complex.
- Most fish run 1–3 lbs; specimens above 5 lbs are genuine catches, though larger individuals turn up in remote Amazon tributaries.
What to know
Habitat Distribution
- Native to Brazil; H. curupira ranges across the Amazon basin including the rios Negro, Tapajós, Xingu, Tocantins, Trombetas, and Capim; H. brasiliensis is endemic to northeastern Brazil.
- Extremely adaptable — lakes, reservoirs (represas), farm ponds (açudes), natural lagoons, and slow river stretches all hold fish.
- Prefers calm or slow-moving water with dense marginal vegetation, submerged timber, and shaded banks where it can hold tight and wait for prey.
- Tolerates low-oxygen, warm, and even seasonally stagnant water that excludes most other predators — one reason it turns up almost everywhere.
Key Locations
- Rio Negro tributaries and backwaters (Amazon basin) — H. curupira is a common bycatch while fishing for peacock bass in flooded jungle margins.
- Rios Tapajós, Xingu, Tocantins, and Trombetas — all confirmed range for H. curupira in the Amazon basin, with fish accessible from river camps.
- Northeastern Brazil reservoirs and açudes — H. brasiliensis is endemic here; farm ponds and public reservoirs throughout Bahia and surrounding states hold fish.
- Pantanal region — traíra are present among the 320-plus species of this floodplain system, often encountered while fishing oxbow lakes and flooded margins.
Specific Spots
- Submerged root mats and fallen timber along shaded banks — traíra tuck into these tight and rarely move far to chase a lure, so put the cast right on the structure.
- Weedline edges in lakes and reservoirs, especially where aquatic vegetation meets open water; fish hold in the shadow of the canopy and dart out to strike.
- Deep, slow pools in rivers where current slackens against a bend or undercut bank — these pockets concentrate fish during midday heat.
- Shallow flats adjacent to structure at dawn and dusk, when fish move out of cover to feed actively before retreating as light intensifies.
Traíra FAQ
Answers from onWater's species guide.
What are the best lures and bait for Traíra?
Topwater lures, prop baits, walk-the-dog stickbaits, and hollow-body frogs worked slowly with long pauses near cover, produce the most explosive strikes and are the preferred method among Brazilian lure anglers.
What flies work for Traíra?
Foam or deer-hair poppers imitating frogs are the most exciting option, work them with long pauses between strips so the rings settle before the next twitch, giving the fish time to commit.
When is the best time to fish for Traíra?
Dry season (roughly May–September in the Amazon basin) concentrates fish in remaining pools and lake margins, making them easier to locate and more willing to strike.
How do you catch Traíra?
Most Brazilian anglers fish traíra from the bank or a small boat, casting topwater lures or hard minnows tight to cover, fallen timber, root mats, and weedline edges, and working them slowly with deliberate pauses.
What do Traíra eat?
Primarily smaller fish, lambaris (small characins), tilápia fingerlings, and whatever baitfish share the water, making hard-bodied minnow lures and soft-plastic swimbaits the go-to imitations.
