Trachinotus ovatus, commonly known as the ovate pompano or derbio, is a species of marine fish in the family Carangidae. It is characterized by its compressed, oval-shaped body and silvery coloration. This species is a fast-swimming pelagic fish, often found in coastal waters, and is known for its schooling behavior, particularly when young. It is a popular target for recreational anglers and is also of minor commercial importance in some regions.

- Pinna dorsale
- Two dorsal fins; the first with 6-7 short, stout spines, the second with 1 spine and 22-25 soft rays. The anterior rays of the second dorsal fin are elongated.
- Pinna caudale
- Deeply forked, with long, slender lobes.

Consigli per l'identificazione
Body Shape
Look for the distinctly ovate and compressed body, which is characteristic of the species.
Coloration
The overall silvery appearance with a darker back and lighter belly is a key indicator. Faint vertical bars may be present in juveniles.
Fins
Note the deeply forked caudal fin and the elongated anterior rays of the second dorsal and anal fins. The absence of scutes on the lateral line is crucial for distinguishing it from other carangids.
Size
Consider the typical adult size range of 30-50 cm, though larger specimens can occur.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found in shallow coastal waters, from the surface down to about 70 meters (230 feet), but more commonly in the upper 30 meters (100 feet).
- Ambiente
- Prefers sandy bottoms, surf zones, estuaries, and rocky reefs. Often found near shorelines, beaches, and in bays. Juveniles frequently inhabit very shallow, protected areas.
- Areale geografico
- Eastern Atlantic Ocean, including the Mediterranean Sea, from the Bay of Biscay south to Angola. Also found in the Black Sea.

Fast Swimmersbehavior
Trachinotus ovatus are known for their incredible speed and agility, making them challenging and exciting targets for anglers.
Schooling Behaviorbehavior
Juvenile Trachinotus ovatus often form large schools in shallow coastal waters, providing a degree of protection from predators.
Dietary Flexibilitybehavior
While primarily carnivorous, feeding on small invertebrates, Trachinotus ovatus can exhibit some dietary flexibility, occasionally consuming plant matter or detritus.
No Scutesinteresting
Unlike many other members of the Carangidae family (jacks and trevallies), Trachinotus ovatus lacks scutes (bony plates) along its lateral line, a key identification feature.
Mediterranean Presenceinteresting
Trachinotus ovatus is one of the more common pompano species found throughout the Mediterranean Sea, where it is a valued food fish.

Specie simili
Permit
Trachinotus falcatus
Permit generally have a more elongated body shape, a more pronounced forehead, and typically grow larger. They also often exhibit a yellowish wash on their fins, and their dorsal and anal fin lobes are usually longer and more falcate than T. ovatus.
Florida Pompano
Trachinotus carolinus
Florida Pompano typically have a more yellowish belly and fins, and their body is generally less deep and more elongated than T. ovatus. The number of dorsal and anal fin rays can also differ slightly.
African Pompano
Alectis ciliaris
African Pompano (threadfin trevally) are easily distinguished by their extremely long, filamentous dorsal and anal fin rays in juveniles, which shorten with age. Adults have a much more angular head profile and a more silvery, reflective body.
