The fish of the Jack or Carangidae Family are known in Mexico’s fishing areas as jureles and pámpanos. The family is very large and includes the Jacks, Amberjacks, Crevalles, Jack-Mackerels, Leatherjacks, Lookdowns, Pilotfish, Pompanos, Scads, and Trevallies with more than 150 global species in 30 genera found in all tropical and subtropical seas. They are schooling pelagic fish with large continental distributions and are normally found near the surface far off shore. The Jacks are generally silvery in color being darker dorsally and lighter ventrally. They range in length from 30 cm (12 inches) to 1.7 meter (5 feet 7 inches) and in weight from 0.5 kg (1 pound) to 41 kg (90 pounds). They have widely differing body shapes. Most are powerful mid-water swimmers characterized by streamlined compressed aerodynamic bodies with slender tail bases and deeply forked caudal fins with equal lobes. Their heads vary from moderately long and rounded to short, deep, and very compressed with eyes that are small to large. Their snouts are pointed to blunt and they have large gill openings. Their anal and dorsal fins are low but often have elongated rays at the front. Their anal fin has two detached spines (a key to identify this family), one additional spine, and 15 to 39 low spines that are short to elongated in length. Their first dorsal fin is moderate to very low in height with four to eight spines, and their second dorsal fin has one spine and 18 to 44 rays. Their lateral line is arched or elevated above the pectoral fins and straight posteriorly extending into the caudal fin. Many Jacks have prominent scutes on the rear portion of their lateral line. Their bodies are covered with small scales.

The Jacks are voracious predators feeding primarily on small fish; some species also consume crustaceans and mollusks, while the Scads mainly eat planktonic invertebrates. Although not strictly reef fish, Jacks are common over rocky structures, along the edge of reefs, and sometimes adjacent to steep slopes and large “drop-offs”. They frequently travel in large schools and roam considerable distances, following schools of smaller bait fish. They spawn pelagically, releasing large numbers of tiny buoyant eggs that travel the globe, carried by currents. Most Jacks are highly esteemed as food fish and are targeted by both commercial and sport fishermen. They are considered to be very important commercial fish with annual catches in excess of 1 million tons from the western central Pacific alone where they are caught via trawls, purse seines, traps and long lines. The Caranx, Seriola, and Trachinotus genera are highly regarded as sportsfish.
