Location Habitat

Occurs in the western Atlantic Ocean from Nova Scotia, Canada, to Uruguay, including the Gulf of Mexico and occasionally in the West Indies. In the eastern Atlantic it is found from Portugal to Angola, including the Western Mediterranean. Generally in neritic waters over the continental shelf, from the coastline, where it is common on shallow flats, to offshore waters. Adults ascend rivers. Juveniles abundant in brackish estuaries with muddy bottoms, near sandy beaches and on seagrass beds, entering lagoons and lower courses of rivers. They form fast-moving schools, although larger fish may be solitary. They feed on smaller fish, shrimp, and other invertebrates. Often grunts or croaks are heard when caught. Eggs are pelagic

Biology & Physical Description

Also called common jack, toro, cavally, cavalla, horse crevalle. The crevalle jack has a high, blunt head with a black spot on the back edge of the gill cover. The back is slate to bluish-black in color and the lower half is a bright silvery-yellow, with the anal fin being especially yellow. Crevalle jacks school by size, with the largest fish forming the smallest schools. When prey species are sighted, often near the surface, they make spectacular slashing attacks, with prey fish attempting to escape leaping in panic in every direction. After attack, they regroup for their next assault. Deep, compressed body. Blunt head with black spot on rear edge of gill cover. Hard scutes forward of sickle-shaped tail. Color usually yellowish with white undersides. The crevalle jack is the common jack of in shore oceanic waters. The species apparently can tolerate a wide range of salinities and occurs around off shore reefs, in coastal waters, harbors and protected bays, over highly saline shallow flats, in brackish waters at river mouths, and has even been known to travel up coastal rivers. There is a rounded black spot at the lower base of the pectoral fin of the crevalle jack that is found in no other jacks in the area. There is also a distinct, vertically elongate black spot on the operculum. Enlarged scales or scutes, numbering about 30, extend in a line to the base of the tail fin. The similar horse-eye jack has no pectoral fin spot and 26-35 scutes. A voracious predator, it feeds primarily on smaller fishes, which it often chases onto beaches or against seawalls. In open water, jacks will herd bait fish into a tight mass, then rush in from all sides. The crevalle jack also feeds on shrimp and other invertebrates and on garbage dumped from boats. This superb light tackle species can be taken by spinning, fly fishing, trolling, or surfcasting. Lures should be retrieved at a fast pace without pausing or stopping as jacks tend to lose interest in anything that doesn't act normally. Most jacks are not highly valued as food, though they are edible. Dorsal spines (total): 9; Dorsal soft rays (total): 19-22; Anal spines: 3; Anal soft rays: 15 - 18. Diagnosis: Scutes on lateral line 23 to 42. No scales on chest, except a small mid-ventral patch in front of pelvic fins. Upper profile of head steep. Maxilla ending approximately below or beyond posterior edge of eye (in adult). Front of soft dorsal and anal fins elevated; olivaceous to bluish green dorsally, silvery to brassy on the sides; prominent black spot posteriorly on gill cover at level of eye, another at upper axil of pectoral fins, and often a third on lower pectoral rays; caudal yellowish

Geographic Species Map (Fishbase.org Map)

Summary of Distribution: Eastern Atlantic: Portugal to Angola, including the western Mediterranean. Western Atlantic: Nova Scotia, Canada and northern Gulf of Mexico to Uruguay, including the Greater Antilles. Absent from eastern Lesser Antilles. Indian Ocean records are probably misidentifications of Caranx ignobilis. Reports from Pacific refer to Caranx caninus, which may be conspecific.

Sport Fishing Techniques

Gill nets

Gill-nets are the dominant gear in the Indian Ocean. Gill-nets are used in artisanal and semi-industrial fisheries, contributing to 30-40% of the total catch. The net design is comprised of continuous panels of uniform mesh size, aimed to trap fish behind the gills. The International Sustainable Seafood Foundation (ISSF) notes that rates of sharks and turtle by-catch in Indian Ocean gill-net fisheries are high..

Tackle & Baits

Most Jacks are fairly small and are caught on the full range of light tackle by anglers seeking other game. If you target larger Jacks, say 10 pounds or more, sturdy spinning, baitcasting and fly tackle should be used, with lines no less than 8-pound test. Small Jacks, such as those frequently encountered on shallow flats, will gulp down almost any sort of natural bait, live or dead, as well as all the popular casting and flyrod lures. Big Crevalles, however, generally like their meals moving very fast. To assure hookups, you have to use fresh and frisky live fish, or retrieve your artificial lures rapidly, noisily, or both. Topwater plugs are good, as are fast-whipped jigs. Fly rodders often have to work very hard, stripping their streamers or poppers as fast as their elbows will move.

Game Rating

Game Rating : 8.5/10

Game Description :

Few fish can out-pull a Crevalle of equal size. The fight is unspectacular but dogged, the usual pattern being a long first run. Jacks use their flat sides to good advantage when waging a tug-o-war.

Food Rating

Game Rating : 3/10

Game Description :

Poor by most tastes. Most of the meat is dark red and of strong flavor.
