Barred Grunt

Barred Grunt

The barred grunt is a small bottom-dwelling marine fish native to Brazil's Atlantic coast, present from the northeastern states south to Santa Catarina.

It turns up regularly in artisanal catches and as shrimp-trawl bycatch — particularly in Pernambuco — and shows up in surf zones, estuaries, and shallow coastal flats. Not a primary target for sport anglers, but caught incidentally from shore and small boats.

Scientific Name: Conodon nobilis

Also known as Corcoroca, Corocoroca

Physical Characteristics:
  • Elongate, moderately robust body, laterally compressed; brownish back fading to white below, with yellowish horizontal lines along the sides.
  • Eight wide, dark vertical bars across the upper body — the clearest field mark that separates this species from similar grunts.
  • Soft dorsal, anal, and pelvic fins are distinctly yellow; preopercle edge strongly serrated with two large spines at the angle.
  • Common size around 25 cm; maximum recorded near 35 cm for females, with most fish well under 400 g.

What to know

Habitat Distribution

  • Native to Brazil's Atlantic coast; range runs from the northeastern coast south to Santa Catarina, in subtropical and tropical waters.
  • Primarily a shallow-water, bottom-oriented fish of sandy and muddy coastal areas, surf zones, and estuarine margins; occasionally enters brackish water.
  • Found from the surface down to about 100 m, but most common in shallow inshore waters — surf zones serve as nursery habitat for juveniles rather than estuaries proper.
  • Also recorded along rocky shores and around structures, though soft-bottom sandy flats are the core habitat.

Key Locations

  • Pernambuco coast — documented as a frequent bycatch species in shrimp trawl fisheries operating in shallow coastal waters here.
  • Santa Catarina — the southern limit of the species' confirmed Brazilian range, where population biology studies have been conducted.
  • Northeastern Brazil broadly — the species is common in demersal coastal assemblages throughout this region's sandy and estuarine shores.

Specific Spots

  • Sandy bottom surf zones close to shore — juveniles concentrate here, using wave turbulence as cover while feeding on small invertebrates stirred up by the surge.
  • Soft-bottom flats near estuarine mouths, where tidal flow concentrates shrimp and small crustaceans that this fish feeds on.
  • Rocky outcrops and jetty bases adjacent to sandy substrate — the mix of hard structure and soft bottom draws feeding fish.

Barred Grunt FAQ

Answers from onWater's species guide.

What are the best lures and bait for Barred Grunt?

Natural shrimp, live or fresh-dead, is the most consistent bait, directly matching the crustaceans this fish actively hunts on the bottom. Cut fish bait and small pieces of squid fished on a bottom rig also produce, especially when drifted over sandy flats near estuarine mouths.

How do you catch Barred Grunt?

Barred grunt are not a primary sport target in Brazil; they are most often caught incidentally by artisanal fishers working sandy coastal flats and surf zones with bottom rigs and natural bait, or taken as bycatch in shrimp trawls.

What do Barred Grunt eat?

Feeds mainly on small bottom-dwelling crustaceans (shrimp and crabs), bony fish, and mollusks (snails and bivalves), all forage found on or near the seafloor. Small shrimp imitations, cut bait, and natural shrimp are the most direct match.

Where do Barred Grunt live?

Native to Brazil's Atlantic coast; range runs from the northeastern coast south to Santa Catarina, in subtropical and tropical waters. Primarily a shallow-water, bottom-oriented fish of sandy and muddy coastal areas, surf zones, and estuarine margins; occasionally enters brackish water.
