Targeting giant trevallies on the fly is not for the faint-hearted angler. They are fierce, big, aggressive, and incredibly powerful, all of which are quite often entirely underestimated by new anglers but respected by novice and seasoned fishermen alike. Due to GTs being 100% carnivorous and even cannibalistic at times, they are prime targets with a fly rod. Multiple fly patterns will work when fishing for these fierce fish, and most times, if the fly is presented properly and stripped the correct way, it will get eaten. If we had to choose three flies to put into our box, they would be the following:
Our first choice would be a Black Brush Fly. This fly has probably taken down more GTs than any other fly that we use. The combination of adding a hint of purple, red, or olive to the black brush fly also works really well. We often get asked by guests, “What fly works best?” and our reply is standard, “you can use any fly you want as long as it is a Black Brush fly!”
Our second choice would have to be an Olive and Red Semper Fly. Like all Semper patterns, this fly has incredible movement in the water, making them irresistible to any cruising GT. Both of the flies, as mentioned above, are fished in the same way – long and fast as possible. Strips/retrieves need to take place.
And last, but definitely not least, would be a Popper. The Not Your Average Popper (NYAP) has revolutionized fishing for GTs with a Popper and is wildly effective. However, slightly more robust and traditional popper patterns are becoming very popular as they create a more fantastic disturbance on the water. In essence, though, they both have the same concept. Poppers are generally fished over deeper waters, such as drifting on the skiff in the lagoons or casting into the channels as well as floating the outer shallow reef of the atolls. With their violent and water-disturbing effectiveness, they have the ability to draw fish from afar or from the depths.
All of these flies, along with any additional gear you might need, is available on the islands. Alternatively, our guides are fully kitted to tie any flies that may be unavailable. These are our top fly choices for targeting giant trevally in our waters and beyond.
