Carangidae is a diverse family of marine fish belonging to the order Carangiformes. This family includes a wide array of species commonly known as jacks, pompanos, trevallies, scads, and amberjacks. They are typically fast-swimming, predatory fish found in tropical and subtropical waters worldwide. Many species are highly valued in commercial and recreational fisheries.
Caratteristiche fisiche
- Forma del corpo
- compressed
- Colorazione
- Highly variable, often silvery or iridescent, with some species exhibiting darker dorsal surfaces and lighter bellies. Many have yellow or golden fins, and some possess distinctive spots, bars, or patterns. Juveniles often have different color patterns than adults.
- Tipo di squame
- cycloid
- Posizione della bocca
- terminal
- Caratteristiche distintive
- Laterally compressed body, Forked caudal fin, Two dorsal fins (first spiny, second soft-rayed), Anal fin preceded by two detached spines (often embedded in adults), Scutes (enlarged, keeled scales) along the lateral line, especially on the caudal peduncle, Often possess an adipose eyelid
- Pinna dorsale
- Two dorsal fins; the first with 3-9 spines (often recessed in a groove), the second with 1 spine and 18-37 soft rays. The anterior rays of the second dorsal fin are often elongated.
- Pinna caudale
- Deeply forked caudal fin, indicative of fast-swimming pelagic habits.
- Pinna pettorale
- Long, falcate (sickle-shaped) pectoral fins, particularly in many larger species.
- Pinne distintive
- Anal fin similar in shape to the second dorsal fin, preceded by two detached spines (which may be absorbed or embedded in larger individuals). Pelvic fins are thoracic.
Consigli per l'identificazione
Body Shape
Look for the characteristic laterally compressed, fusiform to ovate body shape.
Caudal Fin
The deeply forked caudal fin is a key identifier for most Carangids, indicating their fast-swimming nature.
Scutes
Presence of scutes (enlarged, often keeled scales) along the posterior part of the lateral line, especially on the caudal peduncle, is a definitive family characteristic. The number and extent of scutes vary by species.
Dorsal and Anal Fins
Two dorsal fins (spiny and soft-rayed) and an anal fin preceded by two detached spines are consistent features. The shape and length of these fins can help differentiate genera and species.
Pectoral Fins
Many species, particularly larger jacks and trevallies, have long, falcate pectoral fins.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found from surface waters down to several hundred meters, with some species inhabiting deeper reefs and others preferring shallower coastal areas.
- Ambiente
- Primarily marine, inhabiting tropical and subtropical oceans worldwide. They are found in a variety of habitats including open pelagic waters, coral reefs, rocky reefs, estuaries, and sandy bottoms. Many species are schooling fish.
- Areale geografico
- Circumglobal in tropical and subtropical waters of the Atlantic, Indian, and Pacific Oceans.

- Dimensione minima della vasca: 500 gallons (for smaller species, much larger for larger species)
- Temperatura: 72-78°F (22-26°C)
- Livello di pH: 8.1-8.4
- Durezza: 8-12 dKH
- Compatibilità: Generally not suitable for typical home aquariums due to their size, predatory nature, and need for vast swimming space. Only compatible with very large, species-specific or predator tanks.
- Requisiti speciali: Require very large tanks with strong filtration and excellent water quality. Many species are pelagic and need ample open swimming space. Live or fresh frozen meaty foods are essential. Some species are schooling and require conspecifics.
Informazioni in natura
- Stato di conservazione: least concern
- Stagionalità: Many species are available year-round, with peak seasons varying by species and geographic location, often tied to spawning migrations or feeding aggregations.
- Prezzo di mercato: Varies greatly by species and region, from moderate to high.
- Importanza commerciale: high
- Sapore: Generally firm, white, and flaky flesh with a mild to medium flavor, often described as rich or slightly oily depending on the species.
- Consistenza: Firm, meaty.
- Metodi di cottura: grilling, baking, frying, sashimi, smoking
- Valore nutrizionale: Good source of protein, Omega-3 fatty acids, and various vitamins and minerals.
Fatti chiave
Fast Swimmersbehavior
Carangids are renowned for their streamlined bodies and deeply forked tails, enabling them to be incredibly fast and agile swimmers, crucial for both hunting prey and escaping predators.
Schooling Behaviorbehavior
Many species of Carangids form large schools, especially as juveniles and sub-adults, providing protection from predators and increasing foraging efficiency.
Ecological Importanceinteresting
As apex or meso-predators in many marine ecosystems, Carangids play a vital role in controlling populations of smaller fish and invertebrates, contributing significantly to food web dynamics.
Angler's Delightinteresting
Due to their fighting prowess and often large size, many Carangid species (like Giant Trevally and Amberjack) are highly prized by recreational anglers worldwide.
Scutesamazing
The presence of scutes, which are enlarged, often keeled scales along the lateral line near the tail, is a unique and defining characteristic of the Carangidae family.
Informazioni di sicurezza
Maneggiare con cura- Livello di sicurezza: caution
- Velenoso: No
- Commestibilità: edible
- Note sul maneggio: Most Carangids are not venomous, but their sharp fin spines (especially the dorsal and anal spines) and gill covers can inflict painful wounds. Larger species can also deliver powerful bites. Handle with care, using gloves and appropriate tools to avoid injury. Some larger species, particularly those feeding on reef fish, can accumulate ciguatera toxins, making them unsafe for consumption in certain regions or at larger sizes.
Specie simili
Mackerel Scads
Decapterus spp.
Generally more slender and cylindrical bodies compared to many other Carangids, with a prominent adipose eyelid and a series of finlets behind the dorsal and anal fins in some species (though not true finlets like Scombridae).
Cobia
Rachycentron canadum
While superficially similar in body shape and often found in similar habitats, Cobia have a distinct dark lateral stripe, a flattened head, and 7-9 short, isolated dorsal spines not connected by a membrane, unlike the continuous spiny dorsal fin of Carangids.
Barracudas
Sphyraena spp.
Barracudas have a much more elongated, cylindrical body, a distinctly pointed head with a large mouth and prominent teeth, and two widely separated dorsal fins. They lack the scutes on the lateral line characteristic of Carangids.
