5 Types Of Jack Fish Ranked By Size
Giant Trevally (Caranx ignobilis)
The giant trevally (Caranx ignobilis) is the largest member of the jack family and is also known as the lowly trevally, barrier trevally, ronin jack, giant kingfish, or ulua. It is a species of large marine fish that can grow up to 1.7 meters (5.6 feet) in length and weigh over 60 kg.
The giant trevally is distributed throughout the tropical waters of the Indo-Pacific region, with a range stretching from South Africa in the west to Hawaii in the east, including Japan in the north and Australia in the south.
These clever hunters ambush prey fleeing from other large predators like monk seals and sharks. The Giant Trevally can be recognised by its steep head profile, strong scutes on the body, and its silvery-grey to black colouration, with a scattering of small white spots on the upper body.
Greater Amberjack (Seriola dumerili)
The greater amberjack (Seriola dumerili) is a species of predatory ray-finned fish in the family Carangidae, the jacks and pompanos. It is also known as the allied kingfish, great amberfish, greater yellowtail, jenny lind, Sea donkey, purplish amberjack, reef donkey, rock salmon, sailors choice, yellowtail, and yellow trevally.

The greater amberjack has a body colouring that varies from brownish to bluish-grey on the dorsal surfaces contrasting with a silver-white ventral surface. It has a dark amber strip on its head, extending from its nose to its first dorsal (back) fin, which becomes more defined when the fish is excited or feeding.
The greater amberjack is a large predatory fish that feeds primarily on fishes such as the bigeye scad, also on invertebrates. It is a popular quarry species for recreational fisheries and is important in commercial fisheries.
The greater amberjack is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.
Almaco Jack (Seriola revoliana)
The almaco jack (Seriola rivoliana) is a game fish of the family Carangidae, which includes jacks and amberjacks. It is also known as the longfin yellowtail, silvercoat jack, deep-water, falcate, European or highfin amberjack, rock salmon, longfin or yellow kingfish.
The almaco jack is a fast-swimming predator that feeds both day and night on small bony fishes (baitfish), squid, octopus, crab, and shrimp. It is a demersal and pelagic fish that is mainly oceanic and can be found in depths ranging from 3 to 340 meters.
The almaco jack can grow up to 1.2 meters (3.9 feet) in length and weigh up to 60 kg. It has a short upper jaw, with a yellowish streak from the jaw across the eyes to the first dorsal fin.
The almaco jack has thick and dense flesh, similar to tuna, and can be passed off as white albacore if prepared as sushi. The almaco jack is a candidate species for Florida aquaculture and is sustainably managed under U.S. regulations.
Crevalle Jack (Caranx hippos)
The crevalle jack (Caranx hippos) is a species of large marine fish classified within the jack family, Carangidae. It is also known as the common jack, black-tailed trevally, couvalli jack, black cavalli, jack crevale, or yellow cavalli.
The crevalle jack is distributed across the tropical and temperate waters of the Atlantic Ocean, ranging from Nova Scotia, Canada to Uruguay in the western Atlantic and Portugal to Angola in the eastern Atlantic, including the Mediterranean Sea. It is distinguishable from similar species by its deep body, fin coloration, and a host of more detailed anatomical features, including fin ray and lateral line scale counts.

The average size of the crevalle jack in Texas waters is 2-5 pounds, but larger sizes are common and 25 pounds is not unusual. The crevalle jack is a highly predatory species of marine fish that feeds on smaller fishes, squid, and crustaceans.
Yellow Jack (Carangoides bartholomaei)
The yellow jack (Carangoides bartholomaei) is a species of marine fish in the jack family, Carangidae. Here are some key facts about the yellow jack:
– The yellow jack is one of only two representatives of its genus present in the Atlantic Ocean, inhabiting waters off the east coast of the Americas from Massachusetts in the north to Brazil in the south, as well as a number of offshore islands.
– The yellow jack can be distinguished from closely related species by the length of the jaw, as well as counts of the rays in the fins.
– It is a fairly large fish, growing to a recorded maximum length of 1 meter (39 inches), and a weight of at least 14 kilograms (31 pounds).
– Juvenile yellow jacks are often found near the shore on seagrass beds or often associated with jellyfish or floating Sargassum.
– The yellow jack is a gamefish and is also important in commercial fisheries.
– Yellow jacks are known to spawn in the summer months off Cuba (between February and October elsewhere), and males reach sexual maturity at a length of 30 cm.
– Adults are pale yellow-green-blue dorsally, becoming silver on the underside, often with a yellow cast, and the tail is yellow.
Overall, the yellow jack is an important species of marine fish that is found in the Atlantic Ocean and is valued both for its commercial and recreational importance.
