flying gurnard
Dactylopterus volitans · Dactylopteridae · predator
Fish of sand and reef bottoms, with huge fan-shaped pectoral fins, which it uses to explore the bottom. It shows up now and then on the line and also gets caught in nets.
Also called: coió, avuador-carga-de-palha, peixe-voador, volador, alón volador, flying gurnard

everything about the flying gurnard
who is the flying gurnard
Fish of the family Dactylopteridae, with a spindle-shaped body and huge fan-shaped pectoral fins, which look like wings, although it does not fly. It lives on sand, mud and rock bottoms, from 1 to 100 m, in tropical and subtropical waters, and also enters brackish water. It reaches 50 cm and 1.8 kg, and its common size is around 38 cm. It explores the bottom with the free part of its pectoral fins and mainly eats crabs, mollusks and small fish. It occurs on both sides of the Atlantic: on the western coast, from Canada to Argentina, and from the English Channel to Angola on the eastern coast. It is caught now and then on lines and also gets caught in nets.
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 flying gurnard.
fun facts
- It uses the free part of its pectoral fins to explore the bottom.
identification
Spindle-shaped body, with a huge fan-shaped pectoral fin whose front rays are separated and form a small lobe. It is the most visible mark of the species and sets it apart from other bottom fish of the region. Despite its popular name of flying fish (peixe-voador), it is not related to the true flying fishes (Exocoetidae). It also has no venom gland.
where found
In Latin America it occurs from Brazil to Argentina, in the Caribbean, Mexico and Venezuela, on shallow sand, mud and reef bottoms.
Habitat: Sand, mud and reef bottoms, 1 to 100 m, often near the coast.

rules for the flying gurnard
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 the angler and has no venom gland, but the dorsal spines call for care when holding it. Hold it by the body, away from the pectoral fins, and release it quickly.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01122, b = 2.95; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). 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:
