How to catch jack crevalle 

One can use spinning, fly-fishing or surfcasting techniques to catch the jack crevalle fish with live bait such as pinfish or mullet.


A 7 foot medium action spinning rod with a 2500-3000 series reel will do well for jack crevalle fishing in most inshore finds. Heavy spinning tackle or medium conventional tackle is better suited to fishing for jack crevalle in tight quarters. A 3/0 circle hook is recommended.


One of the easiest ways to locate the most productive spot to catch your Jacks is to look for places in the water where the birds flock , this is because these fishes push baitfish to the surface and the birds attack from above are usually picked up by birds as prey. Hence areas where birds flock the water body is a good place to begin with.

 
They are attracted to fast-moving baits and they enjoy the chase. Cast the bait over and away from the school, and then retrieve it rapidly. If you are fishing in deeper water, quick and aggressive jigs will be effective. If they are closer to the surface, sight casting with topwater plugs is the recommended method. 

Jigs are a great artificial lure to use when drifting the flats. Most of the time the water depth will be ten feet or less. A 1/4 ounce to 1/2 ounce jig is sufficient for this purpose. Most often anglers come across the jack fish while fishing for reds, trouts, flounder, striped fish.
