everything about the blackear wrasse
who is the blackear wrasse
Wrasse of the family Labridae, reaching 20 cm. It occurs in the western Atlantic, from southern Florida and the Bahamas to São Paulo, Brazil. It lives in pale seagrass beds and is uncommon on reefs or in muddy bays, from 1 to 70 m deep. It is protogynous hermaphroditic: it is born female and can become male. During breeding, it forms courtship groups. In fishing it has almost no interest, being small, and it is sold for aquariums.
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 blackear wrasse; in the meantime, see the similar species.
identification
Small specimens are yellowish green, with a black spot ringed in pale red behind the eye and a small black spot on the rear base of the dorsal fin. Large males are dull green, with reddish-orange spots at the center of the scales. The tail has pink, lengthwise and diagonal bands with blue edges. The black spot behind the eye is the easiest sign to see in the smaller fish.
where found
Western Atlantic, from southern Florida and the Bahamas to São Paulo, including the Caribbean. In Brazil it ranges from Ceará to São Paulo, with the reefs of Maranhão.
Habitat: Seagrass beds in clear water, 1 to 70 m deep.

rules for the blackear wrasse
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.
No dangerous spines or venom, and it is harmless to handle.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00955, b = 3.08; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.

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:
