How to recognise it
The Crevalle Jack (Caranx hippos) is a robust fish with a streamlined body. It has a distinctive coloration, typically featuring a dark blue or greenish back, fading to a silver or white belly. The sides may have a yellowish tint. The fins are yellow, particularly the dorsal and anal fins. The mouth is large and extends past the eyes, with sharp teeth.
This species is often confused with the Yellow Jack (Caranx bartholomaei). The key detail that separates them is the presence of a pronounced black spot on the dorsal fin of the Crevalle Jack, which the Yellow Jack lacks.
Where it lives
The Crevalle Jack is found along the Atlantic coast of the United States, from New Jersey to Florida, and in the Gulf of Mexico. It prefers coastal waters, often inhabiting estuaries, bays, and nearshore reefs. The depth range is typically from 10 to 100 feet, but they can be found deeper in some areas.
During warmer months, Crevalle Jacks are more likely to be found in shallower waters, while in cooler months, they may move to deeper areas. They often seek cover around structures such as jetties, piers, and wrecks, which provide shelter and hunting grounds.
When it bites
Crevalle Jacks are most active from late spring through early fall. They prefer water temperatures between 70°F and 85°F. The best times to fish for them are early morning and late afternoon, when they are actively feeding.
Weather conditions can influence their feeding behavior. A passing front may trigger increased activity, while strong winds can make them less predictable. A full moon often leads to heightened feeding, making it a prime time for anglers.
How to catch it
Effective rigs for targeting Crevalle Jacks include the fish finder rig and the popping cork rig. Use baits such as live shrimp, mullet, or pinfish, typically in the 4 to 6-inch range. Lures like topwater plugs and jigs in bright colors, such as chartreuse or white, can also be effective.
For line, use a braided line of 30 to 50-pound test with a fluorocarbon leader of 40 to 60 pounds. Hooks should be in the 4/0 to 6/0 size range. Cast near structures or schools of baitfish, and retrieve your lure with a fast, erratic motion to mimic injured prey.
Size, age and the table
Anglers typically encounter Crevalle Jacks ranging from 10 to 30 inches in length. A trophy Crevalle Jack is generally considered to be over 30 inches. They grow rapidly, reaching sexual maturity by around 2 to 3 years of age, and can live up to 10 years.
Crevalle Jacks are known for their firm, white flesh, making them a popular choice for eating. However, they can have a strong taste, which some may find unappealing. When handling, use wet hands to minimize slime loss, and if releasing, do so quickly to ensure survival.
