Fly Fishing for Bonefish in Seychelles and St Brandon’s Atoll

Bonefish are well known as one of fly fishing’s most famous saltwater targets and are responsible for most anglers’ introduction to the world of fly fishing travel and the thrills of sight fishing. The species’ tendency to feed in shallow water, its fondness for well-presented flies, and its lightning-fast runs make it the perfect fly fishing target. Learn more about fly fishing for bonefish, the best gear, how to improve your chances of success, and where to find the ultimate bonefishing experiences below:

Fast Facts:

• The All Tackle World Record for bonefish stands at a massive 8.61 kg (19 lb), caught off the South African coastline. Remarkably, a bonefish weighing 17.5 lb was landed on St Brandon’s Atoll during our April – June 2023 fly fishing season which was certainly a highlight of our return to the atoll’s abundant waters. While these catches are extraordinary, typical catches of bonefish in Seychelles and St Brandon’s range between 4 – 6lb.
• A micro-migration is witnessed each day as bonefish move in large numbers from deeper reefs and channels onto shallow water flats to feed. This behavior occurs during the incoming and outgoing tide flushes which creates the thrilling shallow water bonefishing experiences synonymous with St Brandon’s Atoll and some of the outer atolls of Seychelles.
• The bonefish’s diet primarily consists of crustaceans, small fish, worms, snails, and mollusks. Check out our list of the best bonefish flies in our gear recommendations below.
• Renowned as one of the fastest fish in the ocean, bonefish can reach speeds of upwards of 64km/h. Given their lack of major spines, tough scales or scoots, their incredible speed serves as their primary defence against predators.

Rigging up for Bonefish

• The best fly rods for bonefish are 9-foot 9wt fast action saltwater fly rods, with the 9ft 9wt G.Loomis NRX+ standing out as our top recommendation.
• The best fly line for bonefish is 9wt tropical/warm water fly lines that match the recommended rod. We recommend the Airflo Superflo Ridge 2.0 flats Universal Taper 9wt fly line.
• The best reels for bonefish have fast line retrieval, a drag system designed for wet wading in saltwater, and a minimum backing capacity of 250 yards of 50lb gel spun or casting braid. The Wade Albula fly reel is our top pick, designed to handle formidable fish like bonefish with ease.
• While the best bonefish leader configuration may vary based on the fishery and flats conditions, we find 9ft 16 lb fluorocarbon tapered leaders to be adequate for most situations. In Seychelles, where various fish species abound, using heavier leaders can better prepare you for any surprises during your flat’s fishing adventure.
• The best flies for bonefish vary depending on the destination. Our favourites include patterns that imitate shrimps and crabs such as; merkin crabs, fleeing crabs, spawning shrimps and gotchas tied in various sizes, weights, and colours, on good quality hooks with weed guards. Fly colours should be drab, white, tan, or a mix of these colours. Small pillow talks tied in chartreuse can be effective when dealing with warmer water conditions.

How to Catch More Bonefish in Seychelles and St Brandon’s Atoll

At home

Practice your casting at home before your fly fishing trip to Seychelles or St Brandon’s

Elevate your saltwater fly fishing game by honing your casting skills before embarking on your adventure to Seychelles or St Brandon’s. Success on the flats depends on delivering your fly precisely to the desired target, overcoming challenges like wind, line drag, and moving targets. Remember, distance is not the sole focus; a cast of 40-60 feet (half the length of the average fly line) is usually sufficient. Practice landing your fly accurately in a hula-hoop at 30ft, 40ft, 50ft, and 60ft regularly leading up to your trip. While hiring a casting instructor can help, consistent practice is the key to improving your casting technique and increasing your chances of success.

The Presentation

Achieving the perfect fly placement depends on several variables, including the destination, water quality, fishing pressure, depth, and tide stage. Your experienced guide will provide invaluable insights into the fishery and instruct you accordingly. In Seychelles and St Brandon’s, during skinny water fishing periods aim to present the fly much closer to the fish than in other fisheries. Ideally, lead the fish by about 2-4 feet, you’ll know you’ve executed this correctly if you observe the fish acknowledge and swim towards your sinking fly. This expert technique ensures an enticing presentation that triggers a bite.

The Retrieve and Hook-set

Setting the hook while fly fishing for bonefish on a typical St Brandon Atoll flat.

Given the nature of the prey items that form a bonefish’s diet, a slow to medium retrieve is most effective. Always allow the fly to sink to the bottom before starting the retrieve, as most of the bonefish’s prey scurry along the seafloor. Keep your rod tip close to the water, removing any slack in the fly line between you and the fly. Often, anglers mistake a fish nibbling the fly when, in reality, the fish has already eaten the fly, and they are feeling tension only during the last part of the retrieve. To increase your chances of a successful hookset, slow down the retrieve as the fish follows the fly. When you feel pressure through the fly line, keep the rod tip pointed downwards and execute a firm strip strike to set the hook securely.

The Fight

Once hooked, be prepared for an adrenaline-pumping battle with the powerful bonefish. As the fish takes off at incredible speed, allow the line to run smoothly through your fingers without any sudden stops to avoid straightening the hook or breaking off the fish. The initial run is exhilarating, watching the bonefish create a rooster tail while taking your fly line and yards of backing across the shallow water flats is a scene commonly witnessed during the average bonefishing session on St Brandon’s and Providence Atoll. Keep your drag set light to medium, maintaining a 45-degree rod angle to apply constant pressure, especially if the fish starts its return journey. Reel in quickly and even walk backward if needed to keep consistent pressure on the fish.

Landing a Bonefish, Handling, and Release

Typical scenes at the end of the fight with a flats caught bonefish.

Landing a bonefish can be a challenge, especially when you are alone on the flats. Ideally, your guide will be nearby with a landing net. To land the fish successfully, guide it towards the net with a slow lift of its head just before it’s ready to be netted. Once in the net, the fish may thrash a bit, but it will eventually calm down. When handling a Bonefish, remember to wet your hands, and have your camera ready to capture the moment. Take a few quick photographs, remove the hook, and allow the fish to recover briefly before releasing.
