Lichia amia, commonly known as the Leerfish or Garrick, is a large, predatory marine fish belonging to the family Carangidae (jacks and pompanos). It is highly esteemed by anglers for its fighting prowess and by commercial fisheries for its flesh. This species is characterized by its streamlined, elongated body, powerful tail, and distinctive coloration. It is an active pelagic predator, often found in coastal waters, estuaries, and sometimes even entering freshwater for short periods.

Consigli per l'identificazione
Body Shape
Look for the elongated, compressed body, typical of a fast-swimming predator.
Dorsal Fin Spines
The most distinctive feature is the series of 7-9 very short, detached dorsal fin spines that are often partially embedded in a groove, preceding the much larger second dorsal fin.
Coloration
The dark blue-grey dorsal side transitioning to silvery flanks and belly is characteristic. Juveniles may show faint vertical bars.
Lateral Line
Observe the lateral line, which has a pronounced arch above the pectoral fin before straightening towards the tail.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found in shallow coastal waters, estuaries, and surf zones, from the surface down to about 50 meters (164 feet). Occasionally found in deeper offshore waters.
- Ambiente
- Coastal pelagic and inshore waters, including sandy beaches, rocky reefs, estuaries, and sometimes entering river mouths. Prefers areas with strong currents and abundant prey.
- Areale geografico
- Eastern Atlantic Ocean, from the Bay of Biscay south to South Africa, including the Mediterranean Sea. Also found in the western Indian Ocean, along the coast of South Africa and Mozambique.

Fatti chiave
Master of the Surfbehavior
Lichia amia is renowned for its ability to hunt effectively in the turbulent surf zones, using its streamlined body and powerful tail to navigate strong currents and ambush prey.
Estuarine Visitorinteresting
Unlike many marine predators, Leerfish frequently enter estuaries and even the lower reaches of rivers, particularly during warmer months, to feed on abundant baitfish.
Angler's Prizeinteresting
Due to its strength and aggressive fighting style, Lichia amia is a highly sought-after game fish, providing a significant challenge for recreational anglers.
Ambush Predatorbehavior
Leerfish often hunt in small groups, herding baitfish against the shore or into shallow areas before launching coordinated attacks.
Rapid Growthinteresting
Juvenile Leerfish exhibit relatively fast growth rates, reaching maturity within a few years, which contributes to their resilience as a species.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: edible
- Note sul maneggio: Lichia amia is a powerful fish and can inflict cuts with its sharp fin rays and strong jaws if not handled carefully. Anglers should use appropriate tools (e.g., lip grippers, gloves) to secure the fish and avoid direct contact with the mouth and fins. No venomous spines are present.
Specie simili
Bluefish
Pomatomus saltatrix
Bluefish have a more robust body, a single dorsal fin (though deeply notched), and lack the detached dorsal fin spines characteristic of Lichia amia. Their coloration is typically more uniformly bluish-green.
Greater Amberjack
Seriola dumerili
Greater Amberjacks have a more fusiform (spindle-shaped) body, a less compressed profile, and a distinct amber stripe running from the snout through the eye to the first dorsal fin. They also lack the detached dorsal fin spines of Lichia amia.
African Pompano
Alectis ciliaris
African Pompano have a much deeper, more compressed body, especially as juveniles with extremely elongated dorsal and anal fin rays. Adults lose these long rays but retain a very deep body profile, unlike the more elongated Lichia amia.
