overview

who is the fourwing flyingfish

Flyingfish of the family Exocoetidae. It reaches 33 cm and forms schools at the surface, both near and far from the coast, from the North American Atlantic to northern Brazil. It jumps out of the water and glides over long distances. It spawns at the surface and down to 20 m depth. In fishing, it is one of the most important commercial species of the eastern Caribbean, and is considered a good fish to eat. It is also used as bait and sold fresh.

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 fourwing flyingfish; in the meantime, see the similar species.

fun facts

  • In the eastern Caribbean, mature adults disappear at the end of spawning, in June, perhaps because they die after spawning.
how to recognize it

identification

Elongated, thick body, slightly flattened underneath, with a short, blunt snout. The back is iridescent blue or green, and the dorsal fin has almost no color. The strongest mark is the very long, dark pectoral fins, with a light triangle at the base and a narrow white edge, and the large pelvic fins, which reach past the origin of the anal fin. It looks like the tropical two-wing flyingfish (Exocoetus volitans), which has grey pectorals.
