everything about the chere-chere grunt

overview

who is the chere-chere grunt

The macasso (chere-chere grunt) is a small grunt, up to 30 cm and 0.3 kg, which FishBase gives on two coasts of the Americas: in the Atlantic, from Panama to Santa Catarina, and in the Pacific, from Mexico to Peru. Recent studies show these are two species: H. steindachneri in the strict sense is Pacific, and the Atlantic fish was described in 2020 as Haemulon atlanticus; this entry follows the FishBase page, which still describes both coasts together. It lives from 0 to 50 m, on sand and gravel bottoms, sometimes on reefs, in schools. Juveniles stay near the beach, in seagrass. It eats bottom invertebrates and is used as bait.

fun facts

  • For a long time it was treated as a single species in both oceans; in 2020 the Atlantic population was given its own name, Haemulon atlanticus.
  • FishBase records that it is used as bait (bait: usually).
  • A 2021 DNA study showed that the Atlantic fish is clearly separate from the Pacific fish.
how to recognize it

identification

Elongated, low-bodied grunt, gray-silver to brown on the back and silvery on the flanks, with dark lines following the scale rows and a large black spot at the base of the tail. Preopercle with a black spot on the lower part. Dorsal with 11 to 12 spines and 15 to 17 soft rays; anal fin with 3 spines and 9 soft rays; large, terminal mouth. It is smaller and more elongated than the macassa (Haemulon parra), which has yellowish spots on the scales.

distribution

where found

open on the large map

In Brazil, from Amapá to Santa Catarina, on sand and gravel bottoms and on coastal reefs, with more collection records from Rio de Janeiro to Santa Catarina. Outside Brazil, the broad FishBase reading includes the Atlantic from Panama to the Guianas and the Pacific from Mexico to Peru (the Pacific population is now H. steindachneri in the strict sense).

Habitat: Sand and gravel bottoms, sometimes coral reefs and rocky areas; juveniles near the beach, over sand next to seagrass.

weather, water and behavior

what affects the chere-chere grunt
sensitivity The little bars show how much each factor affects this species. Five full: it feels it a lot.

cold and cold fronts

Cold water from a front pushes the school off the shallows and out of the seagrass.

atmospheric pressure

Small effect; rough seas after the front make rock and beach fishing hard.

moon

Small effect.

rain

Not very relevant at sea; murky water near the river mouth gets in the way.

water level

Follows the tide over sand and gravel bottoms.

noise

Medium sensitivity; footsteps and motor noise in the shallows drive them away.

wind

Heavy seas prevent beach and rock fishing.

tide

A rising tide brings the school onto shallow bottoms; the falling tide concentrates it in the channels.

depth

Usually to 30 m; juveniles much closer to the beach.

tip from an angler

Small hook and well-secured bait: the macasso steals bait with quick bites.

what the law says

rules for the chere-chere grunt

Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
Conservation: Not on the Brazilian national list (Portaria GM/MMA nº 1.667/2026). We found no specific Brazilian federal rule for the species. The IUCN also assessed H. atlanticus separately, in 2020.

Mexico: up to 10 marine fish per angler per day, no more than 5 of the same species

10 marine specimens per angler per day; no more than 5 of the same species

In Mexican federal waters, recreational fishing for marine species has a limit of 10 fish per angler per day, with no more than 5 of the same species. Fish over the limit may only be kept if released alive. Recreational catch belongs to the angler who holds the permit and may not be sold; fish may not be landed as fillets (filleting is allowed only on board, for consumption during the trip). In spearfishing the limit is 5 fish per day. Fishing from a boat requires a permit. It also applies to the Mexican Pacific, where the species occurs.

catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.

Small, hardy fish: wet your hands, remove the hook quickly and release it carefully.

in the kitchen

Edible, sold fresh on a small scale; often used as bait for larger fish.

how much it weighs without taking it out of the water

Length-weight relationship W = a·Lb (a = 0.0138, b = 3.03; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.

The season weights (months), the time of day and the sensitivities (cold, pressure, moon, wind, rain, tide, strong light, murky water and noise) are the app's editorial estimates, based on the literature below and on the field experience of anglers and guides. They are not official data nor a measurement made for this species, and they may vary by region and year. Closed seasons and legal rules appear in the rules section, with the norm and a link.
