Giant Trevally also love stickbaits such as those made by Heru and Orion. You can use either surface or subsurface stickbaits; my preference is subsurface. You generally retrieve this with a long sweep of the rod and then a pause. The strike usually comes on the pause. With the subsurface stickbaits you can’t see the strike coming, so all of a sudden you just feel a violent yank as the fish tries to pull your arm out of its socket. When fishing over a reef you have to be careful that your expensive stickbait doesn't sink into the rocks. There are a couple of surface stickbaits, such as the Adhek Goby, that I also like. These can be retrieved in a variety of ways, but my favorite is a straight fast retrieve so that it skips on the surface. Oddly enough the GT strikes are pretty accurate on this lure, perhaps because of the constant speed and direction.
No matter how you fish for them, make sure you get a solid hookset. They often grab the lures in their mouths and hold them so tightly that the hooks don’t penetrate and then they just spit the lure out. That's one disadvantage to wooden lures (although I use them extensively); the GT teeth often sink in and make it harder to set the hook. With a hard plastic lure like a Sebile Splasher the lure slides more easily through their mouth and embeds the hook. Regardless of what lure you are using, set the hook hard multiple times. To increase your chances, replace all treble hooks with heavy single hooks as shown. The single hook is harder to shake. They often grab the lure head first. Giant Trevally are without doubt one of the toughest sportfish found in tropical waters. For anglers, GT popping is all about spectacular strikes, intense powerful fights and a safe release after a quick photo. It’s great when it all goes to plan, but these majestic fish live around sharp reefs and nasty territory, and instinctively run for cover once hooked
