everything about the creole-fish
who is the creole-fish
A fish of the family Epinephelidae, the family of groupers and sea basses. It reaches 30 cm and lives on coral reefs and rocky bottoms, between 10 and 66 m, often forming groups above the reef. It feeds mainly on zooplankton, such as copepods, tunicates and shrimp, which it catches in midwater. It occurs in the Caribbean, the Gulf of Mexico and the South American Atlantic coast as far as São Paulo, and also on Atlantic islands to the east, such as Ascension and those in the Gulf of Guinea. In fishing it sometimes appears on the line, is caught in subsistence fishing and serves as bait.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the creole-fish; in the meantime, see the similar species.
fun facts
- It retreats immediately when it feels threatened.
identification
Short head and reddish brown body, paler below. It has a strong reddish orange spot at the base of the pectoral fin and three well-spaced white spots between the lateral line and the base of the dorsal fin. Two blue lines cross the face. It looks like the coney (jabu, Cephalopholis fulva), which lives in the same region, so check these spots and blue lines before deciding.
where found
In Latin America it occurs in the Caribbean, the Gulf of Mexico, Colombia, Venezuela, the Guianas and Brazil, as far as São Paulo.
Habitat: Coral reefs and rocky bottoms, 10 to 66 m, with hunting groups above the reef.

rules for the creole-fish
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 (Ministerial Ordinance GM/MMA No. 1.667/2026).
We found no species-specific rule beyond the region's general rules.
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.
It poses no danger to people. If it is used as live bait, keep it in clean water.
in the kitchen
It is caught in subsistence fishing, for local consumption.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01122, b = 3.04; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
Essential profile: size, length-weight, depth, countries and conservation come from FishBase and the cited regulations, and the texts were written from those sources. Season, time of day, sensitivities, technique and baits and lures are not included yet, because we did not find a good source for this species.

where each number comes from
The weather comes from three independent global models, cross-checked hour by hour: when they agree, confidence goes up; when they diverge, the band between them shows on the chart. Beyond 16 days, we use the GEFS ensemble of 31 simulations: if 20 of the 31 predict rain, the chance of rain is 65%. Sun and moon are calculated astronomically, with no uncertainty.
The index adds up, weighted for each species: time of day (species curve anchored to real sunrise and sunset), moon (transits, rise and set, phase), pressure (3 h trend and 24 h swing), water temperature (in rivers, estimated from air temperature; at sea, estimated by an ocean model), wind, rain, clouds, tide and the month in the species' cycle.

how accurate the forecast is
Accuracy measured in the reference project (4 regions, 93 days, forecast vs. observed): maximum temperature is off by 0.6 °C on average the next day and 1.7 °C at 7 days; rain of 5 mm or more is detected 76% of the time the next day and 57% at 7 days. Detection isn't everything: the false alarm rate isn't published here yet, and 93 days in 4 regions is still a small sample. We now also measure every day, at the app's destinations:
