everything about the smalleye croaker
who is the smalleye croaker
The banana croaker is a fish of the family Sciaenidae, with a spindle-shaped body, reaching 40 cm and up to 570 g, with a common size of 35 cm. It lives in coastal waters and estuaries, on mud and sandy mud bottoms, down to 50 m deep. Juveniles are restricted to brackish water. It feeds mainly on shrimp. It is part of the commercial fishing of the region and is considered an important food fish, sold mainly fresh and salted.
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 smalleye croaker; in the meantime, see the similar species.
fun facts
- Juveniles are restricted to brackish waters.
- In Trinidad, it is one of the best-paid species.
identification
Spindle-shaped body, typical of croakers, with small eyes, as the Spanish name ojo chico (small eye) says. It can be confused with other croakers and weakfish along the coast, but the habit of living on mud bottoms, in coastal waters and estuaries, and its small size, at most 40 cm, help separate it. Juveniles are restricted to brackish water and are hard to recognize without observing the habitat.
where found
It lives in the western Atlantic, from Colombia to southern Brazil. In Latin America, it occurs in Colombia, Venezuela, the Guianas, Trinidad and Tobago, and Brazil.
Habitat: Coastal waters and estuaries, on mud and sandy mud bottoms, down to 50 m.

rules for the smalleye croaker
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 is harmless to handle. Being small, release what you are not going to keep.
in the kitchen
It is an important food fish, sold mainly fresh and salted.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00851, b = 3.07; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.

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:
