Seychelles Big Game Fishing: Reel in the Thrill of a Lifetime

The Seychelles archipelago spreads 115 islands across more than 1.3 million square kilometres of Indian Ocean, and the edge of the Mahé plateau — where coral seabed drops sharply from 60 metres to over 2,000 — sits just 20 to 30 minutes from Victoria Harbour. That short run puts you in blue water holding blue marlin, black marlin, sailfish, yellowfin tuna, wahoo, and giant trevally, all within reach of a half-day charter.

Species, Seasons & the Seychelles Edge

What makes Seychelles exceptional isn’t just the species list — it’s how close the deep water comes. The Mahé plateau, a large shallow coral shelf surrounding the inner islands, drops off abruptly into oceanic depths. Pelagic fish concentrate along that edge, and from the east and south coasts of Mahé you can reach the drop-off in 20 to 30 minutes. That means a half-day outing (4–5 hours) can realistically target yellowfin tuna, mahi-mahi, wahoo, and sailfish without burning half the trip on transit.

The species roster runs deep. Blue marlin and black marlin are present year-round and can exceed 250 kg, with peak numbers September to November. Sailfish, distinguished by their fan-shaped dorsal fin and spectacular aerial fights, are most active October to April. Yellowfin tuna offer explosive strikes and powerful fights year-round, making them an ideal first big game encounter. Wahoo, among the fastest fish in tropical seas at speeds over 70 km/h, are best targeted with fast trolling in warm waters. Dogtooth tuna frequent reefs and deep drop-offs, targeted mainly with vertical jigging, and are known for their relentless resistance. Mahi-mahi (dorado) are colourful, fast, and accessible to beginners, often found near the surface.

Giant trevally (Caranx ignobilis) are the apex predators of Seychelles’ coral flats, reaching weights over 50 kg. Even smaller GTs of 5–10 kg put up a fight that leaves your arms trembling. They prowl both shallow flats and deeper reef edges, making them a target for spin, fly, and popping anglers alike. Bonefish, permit, triggerfish, and milkfish round out the flats species for light-tackle and fly fishing enthusiasts.

The two trade wind seasons shape fishing conditions more than any other factor. The northwest monsoon (November to March) brings calmer seas on the east coasts, with some rain. The southeast trades (May to September) kick up rougher open water but create excellent trolling conditions, particularly for sailfish. The transition periods between the trades — April to May and October to November — offer the calmest, most productive fishing windows across all techniques.

Mahé: Day Charters on the Plateau Edge

Most visitors to Seychelles start on Mahé, and that’s also where the island’s day-charter fleet operates. Victoria Harbour and the surrounding coastal reefs provide access to bottom fishing for snapper, grouper, and emperor fish, but the real draw is the offshore drop-off. A half-day charter (4 hours) from Mahé typically costs around $275–$440, while a full-day offshore trip runs $440–$770. Shared group charters bring the per-person cost down to roughly $140–$220 for a full day.

Charter operators on Mahé include Bedier & Sons Charter (Delfino) in Baie Sainte Anne — 4.9 rating from 34 reviews, trips from $690 for a 29-foot boat. Gerry’s Private Charters – K.Kiss operates out of Bel Ombre with 41 reviews. GAM’S Charters – Bout Time also runs from Bel Ombre. These operators supply rods, tackle, bait, and water; the vessel’s fishing license is handled by the operator. You just show up with sun protection, a hat, polarized sunglasses, and seasickness medication if you’re prone.

Angler reports from FishingBooker give a sense of what a typical outing looks like. One report from September 2025 describes trolling starting 4 nautical miles from the jetty, spotting bird activity, landing bonito and dorado, and fast jigging that produced two jacks. Another report from March 2025 describes an amberjack session that lost jigs and broke a rod — a reminder that big game fishing in Seychelles can be as demanding as it is rewarding.

Praslin & La Digue: Sheltered Fishing in the Inner Islands

Praslin, the second-largest island, offers more sheltered fishing on its leeward sides. The waters here hold reef species and pelagics, and charter services operate from Baie Sainte Anne. The island is connected to Mahé by the Cat Cocos ferry, making it an easy addition to a multi-island itinerary. Fly fishing at Fond de l’Anse on Praslin targets bonefish and trevally in calmer conditions than the open ocean.

La Digue, a short boat ride east of Praslin, has beautiful rocky beaches and similarly varied fishing. The waters around both islands are rich in marine life, and charter operators know the best spots for reef and pelagic species. For anglers who want to avoid the rougher open-sea conditions of the southeast trade wind season, the leeward sides of Praslin and La Digue remain more manageable.

Denis Island & the Outer Atolls: Where the Trophy Fish Live

For anglers who want to step beyond day charters, Seychelles’ outer islands offer concentrated big game and world-class fly fishing. Denis Private Island sits on the edge of the Seychelles Bank, where the drop-off plunges from 60 metres to over 2,000 within a short distance. This creates a concentrated feeding zone for blue marlin, black marlin, dogtooth tuna, and sailfish. Denis Island’s lodge-based fishing program is one of the finest in the region, with guided trips targeting both offshore pelagics and inshore species.

The outer atolls — Alphonse, Cosmoledo, Farquhar, Poivre, and St. Joseph’s — are among the world’s most pristine fisheries. Alphonse Atoll is managed by the Alphonse Fishing Company with strict catch-and-release policies, targeting giant trevally, bonefish, permit, triggerfish, and milkfish on crystal-clear shallow flats. Cosmoledo Atoll is considered by many experts to be the finest permit fishery on the planet, with extraordinary numbers of permit and giant trevally. Farquhar Atoll has extensive shallow flats with exceptional bonefish and GT populations, plus offshore blue marlin and dogtooth tuna nearby.

These outer-atoll trips are not casual add-ons. A week-long fly fishing program at an atoll lodge typically costs $10,000–$17,500 per person, including accommodation, all meals, guided fishing, and charter flights to the outer island. The best weeks book 6–12 months in advance, sometimes longer. Specialist outfitters like Aardvark McLeod (UK) and Yellow Dog Flyfishing (US) offer bespoke Seychelles fly fishing packages covering Poivre, Cosmoledo, and other atolls.

Techniques: Trolling, Jigging, Popping & Fly

Four techniques dominate Seychelles big game fishing, and the one you choose depends on the species you’re after and the time of year.

Trolling is the most widely used method from cruising catamarans and charter boats. Baits or lures are trailed at constant speed targeting marlin, sailfish, yellowfin tuna, wahoo, and mahi-mahi. It’s accessible even for first-time anglers — the skipper sets the speed and depths. During the southeast trade wind season (May to September), trolling conditions are rougher but sailfish action is often at its best.

Vertical jigging drops heavy jigs onto drop-offs at great depth, targeting dogtooth tuna, giant trevally, and amberjacks. It’s active and physically demanding, with intense fights from powerful fish. This technique remains practicable in the shelter of the islands during the southeast monsoon, when open-sea trolling is less comfortable.

Popping uses surface lures cast and worked to provoke explosive surface strikes, especially from giant trevally. A GT hitting a popper on a flat is one of sport fishing’s most visceral moments. Poppers and stickbaits in the 80–150 gram range are standard.

Fly fishing on the outer atolls is the pinnacle of Seychelles angling. Sight-casting to giant trevally charging across a white sand flat, or presenting a fly to a tailing bonefish in crystal-clear water, draws serious fly anglers from around the world. An 8-weight to 12-weight fly rod is standard — a 10-weight is the most versatile for GTs, while a 7–8 weight works for bonefish. Large arbor reels with at least 300 metres of backing, intermediate and floating fly lines, and 20–60 lb fluorocarbon leaders are essential.

Practical Know-How: Regulations, Costs & Logistics

Seychelles makes it straightforward for recreational anglers. No fishing license or permit is needed for individual tourists fishing from shore or on a charter — the Fisheries Act 2014 explicitly exempts recreational fishing vessels from the license requirement. Charter operators must hold a sport fishing vessel permit issued by the Seychelles Fisheries Authority (SFA), so booking with a reputable operator covers that side.

There are specific rules to know. Fishing is prohibited in marine national parks, chiefly St. Anne Marine National Park near Mahé. Spearfishing is banned entirely. Catch-and-release is mandatory for bonefish and strongly encouraged for giant trevally, marlin, and sailfish — most serious operators enforce it as standard practice. For species you keep, the Fisheries (Mahé Plateau Trap and Line Fishery) Regulations 2021 set limits: Emperor Red Snapper and Green Jobfish are capped at 5 fish per day per angler with a minimum size of 32 cm fork length. Recreational catches are for personal consumption only — selling or trading is prohibited.

Getting to Seychelles is straightforward. Seychelles International Airport (SEZ) on Mahé is the only international gateway, with direct or one-stop flights from London, Paris, Frankfurt, Amsterdam, Dubai, Doha, Abu Dhabi, Nairobi, Johannesburg, and other hubs. A visitor’s permit on arrival is available for virtually all nationalities — no advance visa required — valid for up to 30 days. You need a passport valid for at least 6 months, an onward or return ticket, proof of accommodation, and sufficient funds.

Inter-island travel is handled by the Cat Cocos ferry connecting Mahé, Praslin, and La Digue. Charter flights serve the outer atolls, typically arranged through lodges. Car hire is available on Mahé and Praslin — driving is on the left, UK-style. The local currency is the Seychellois Rupee (SCR), but many tourist businesses price in EUR or USD. International cards are widely accepted on Mahé and Praslin; outer atoll lodges are largely cashless.

Before You Go — Seychelles Big Game Fishing

Do I need a fishing license as a tourist?

No. The Seychelles Fisheries Act explicitly exempts recreational fishing by individual tourists from the license requirement, whether fishing from shore or on a charter. The charter operator holds the vessel permit — you don’t need to arrange anything.

What’s the best time for a first-timer?

The transition periods April–May and October–November offer the calmest seas and best all-around conditions. If you’re targeting marlin specifically, aim for September to November. For sailfish on trolling, the southeast trade wind season (May–September) delivers excellent action despite rougher water.

Can I keep the fish I catch?

Recreational catches are for personal consumption only — selling or trading is prohibited. Most species have no specific bag limits, but Emperor Red Snapper and Green Jobfish are capped at 5 per day per angler with a 32 cm minimum. Catch-and-release is mandatory for bonefish and strongly encouraged for marlin, sailfish, and giant trevally.

What if someone gets seasick?

It happens. The open water between Mahé and the drop-off can be choppy, especially during the southeast trade wind season. Bring medication that works for you, and consider a half-day trip rather than a full day if you’re unsure. One angler on Gerry’s Private Charters advised: “If you’re not sure everyone won’t get seasick, come prepared.”

How far ahead should I book?

Day charters on Mahé or Praslin: 1–3 months is usually enough outside peak season (December–January). Outer-atoll lodge programs: 6–12 months ahead, sometimes longer. Start planning early if a specific atoll or week is important to you.

Reeling It In

The edge of the Mahé plateau sits just 20 minutes from harbour, and the same Indian Ocean currents that push marlin and sailfish past those drop-offs also flood the remote atoll flats with giant trevally and bonefish. That proximity — world-class fishing within a half-day trip or a short flight — is what makes Seychelles different from other Indian Ocean destinations. Whether you’re working a popper for GT on a Cosmoledo flat or watching a sailfish greyhound across the wake off Mahé, the archipelago delivers on its reputation.
