Cambriaçu
The cambriaçu is Brazil's smaller, estuarine snook — a native species that runs the country's entire Atlantic coast from the Amazon delta south to Florianópolis.
It lives where rivers meet the sea, and that's exactly where Brazilian anglers find it: in mangrove creeks, tidal channels, and river mouths.
Smaller than the common snook but just as willing to eat, it's a reliable inshore target for light-tackle anglers working brackish and freshwater margins.
Scientific Name: Centropomus parallelus
Also known as Fat snook, robalo-peva, cambriaçu
- Yellowish-brown to greenish-brown back, silvery sides and belly, with a bold dark lateral line running from gill to tail — the snook family's most reliable field mark.
- Deep, compressed body compared to other snooks; large mouth with a protruding lower jaw and bands of small teeth; preopercle edge is serrated.
- Most fish run 20–35 cm; the species reaches 72 cm and up to 5 kg, though fish over 50 cm are uncommon.
- Second anal spine is notably thick and curved — a useful detail when separating it from the common snook (Centropomus undecimalis) in hand.
What to know
Habitat Distribution
- Native to Brazil's entire Atlantic coastline, from the mouth of the Amazon south to the Santa Catarina coast near Florianópolis.
- A true estuarine fish: most at home in mangrove-lined tidal creeks, river mouths, coastal lagoons, and the lower reaches of rivers where salinity is low or absent.
- Tolerates a wide salinity range — from fully fresh river water to occasionally hypersaline coastal lagoons — but consistently gravitates toward fresh and mildly brackish conditions.
- Demersal and shallow-water; typically found from the surface down to about 15 m, over soft mud and sand bottoms.
Key Locations
- The estuaries and mangrove systems of the northeastern coast — from Maranhão south through Bahia — hold cambriaçu year-round in tidal creeks and river mouths.
- The coastal lagoons and estuaries of the southeastern states (Espírito Santo, Rio de Janeiro, São Paulo) are within the species' core range and support consistent inshore fishing.
- The Santa Catarina coast near Florianópolis marks the southern edge of the species' distribution in Brazil, making it a boundary population worth noting.
Specific Spots
- Mangrove root systems at tidal creek bends — roots create current breaks and shade that concentrate baitfish and crustaceans, drawing cambriaçu in tight.
- The mouths of small tidal channels where current funnels prey; fish hold just off the main flow and intercept food moving with the tide.
- Shallow soft-bottom flats adjacent to deeper channels — cambriaçu move onto these to feed during high water and pull back to the channel edge as the tide drops.
- Submerged structure (fallen timber, dock pilings, bridge supports) in brackish river sections, where fish use the shade and eddy to stage.
Cambriaçu FAQ
Answers from onWater's species guide.
What are the best lures and bait for Cambriaçu?
Live or artificial shrimp are the most consistent producers, shrimp-pattern soft plastics on a light jig head fished near the bottom or under a float cover both the crustacean and baitfish sides of the diet.
What flies work for Cambriaçu?
Shrimp-pattern flies (Merkin Crab, EP Shrimp) fished on a slow strip near the bottom imitate the crustaceans that make up a large part of the diet, dead-drift them through tidal current, then twitch to trigger the take.
When is the best time to fish for Cambriaçu?
Fishing holds up year-round along the warmer northeastern and northern coast, where water temperatures stay high and fish remain active through all months.
How do you catch Cambriaçu?
Most anglers in Brazil target cambriaçu from small boats or by wading tidal flats and mangrove creek edges, working lures or live shrimp through current breaks and along root systems.
What do Cambriaçu eat?
Small fish and crustaceans, shrimp and small crabs especially, make up the bulk of the diet. Small shrimp-imitating soft plastics or live shrimp under a float are the most direct translation of this at the end of your line.
