Curimatá-comum
Curimatá-comum is a bottom-feeding characin native to the small and mid-sized coastal rivers of northeastern Brazil, from Bahia northward through the semiarid interior.
It travels in large schools, scrapes detritus and organic matter off the riverbed, and is a staple food fish for riverside communities. Farmed widely across the Northeast and Amazon region, it has become Brazil's second most exported farmed fish species.
Scientific Name: Prochilodus brevis
Also known as Curimatá, Curimatã comum, Curimbatá, Brazilian bocachico
- Deep, compressed silver body with noticeably rough, large scales; dark spots or bands on the dorsal fin and tail fin distinguish it from plain-sided relatives.
- The mouth is the key ID feature: a fleshy suction disc with thick lips and rows of small, comb-like teeth — built for scraping algae and detritus off hard surfaces.
- Most fish run 20–30 cm and weigh under 500 g; the recorded maximum is about 32.8 cm and 540 g, making it a small-to-medium table fish.
- Easily confused with the curimatã-do-parnaíba (P. lacustris) and curimatã-pacu (P. argenteus); range is the clearest separator — P. brevis belongs to the eastern Northeast and Bahia coastal drainages.
What to know
Habitat Distribution
- Native to small and mid-sized coastal river drainages of northeastern Brazil, with records extending south into Bahia; not found in the Amazon or São Francisco mainsystems.
- Lives in rivers, backwater lagoons, and farm reservoirs (açudes) — the açudes of the semiarid Northeast are a core dry-season refuge for the species.
- Prefers the shallower benthopelagic zone, typically 0.5–5 m, over muddy, rocky, or log-strewn bottoms where organic matter accumulates.
- Has been raised in rice-field aquaculture in Bahia and farmed commercially across northeastern and Amazonian states.
Key Locations
- Açude Marechal Dutra, Rio Grande do Norte — a studied population site in the semiarid Northeast.
- Coastal river drainages of Ceará, Rio Grande do Norte, and Paraíba — the core native range for wild populations.
- Bahia — southern extent of the natural range, with records from river systems there.
Specific Spots
- Muddy, silty banks and pool tailouts where detritus settles — this is where the fish spend most of their time scraping the substrate.
- Submerged logs, rocks, and woody debris concentrate schools; the biofilm that grows on hard surfaces is a primary food source.
- During the dry season, deep pools and açude basins hold the largest concentrations as surrounding shallows dry up.
- Shoals move into shallower margins early morning and late afternoon; midday heat pushes them deeper.
Curimatá-comum FAQ
Answers from onWater's species guide.
What are the best lures and bait for Curimatá-comum?
Fermented or dough-based baits, fermented corn, masa, or commercially prepared curimatá paste baits, are the go-to across the Northeast; the fish's detritivore diet means it responds to smell and texture more than movement.
When is the best time to fish for Curimatá-comum?
Dry season (roughly June–November in the Northeast), fish concentrate in pools, lagoons, and açudes as rivers drop; this is the most productive period for anglers. Early dry season, fish are actively feeding after the wet season and in good condition.
How do you catch Curimatá-comum?
Most anglers fish from the bank or from small boats anchored over deep pools and açude basins, using bottom rigs baited with fermented or dough-based baits. Schools are located by working likely muddy-bottomed pools and lagoons, particularly during the dry season when fish are concentrated.
What do Curimatá-comum eat?
Feeds almost entirely on detritus, algae, and organic sediment scraped from the bottom, its comb-toothed suction mouth is purpose-built for this. Bait fishing with dough balls, fermented corn, or masa-style baits pressed onto a hook imitates this feeding style and is the standard approach.
Where do Curimatá-comum live?
Native to small and mid-sized coastal river drainages of northeastern Brazil, with records extending south into Bahia; not found in the Amazon or São Francisco mainsystems.
