Seychelles Fishing Adventures: Deep Sea Fishing & Island Casting Hotspots

On Cousine Island, the fishing day starts before the sun clears the horizon. Guests wade barefoot into the shallows with hand-lines, targeting bonefish and trevally that patrol the surf zone. By midday, the same anglers might be chasing yellowfin tuna beyond the reef, and by evening, the catch appears grilled with local spices or simmered into a coconut curry. Seychelles offers that kind of range — shoreline casting on private beaches and deep-sea charters chasing pelagic game fish, often on the same day.

The archipelago spans 115 islands spread across 1.3 million square kilometres of Indian Ocean, which means fishing conditions vary dramatically by location and season. This guide covers the best islands for both shore-based and offshore fishing, what species to expect, when to go, and the practical realities of planning a trip — including the conservation rules that shape how anglers operate here.

Navigating Seychelles’ Fishing Islands

The inner granitic islands — Mahé, Praslin, La Digue — offer the easiest access and most charter options. The outer coral islands and atolls require more planning but deliver bigger fish and fewer boats.

Mahé Island, the largest in Seychelles, hosts the highest concentration of charter companies and is the logical starting point for most visitors. Praslin Island offers similar access with the bonus of being closer to prime reef fishing grounds. For anglers willing to trade convenience for solitude, the outer islands like Denis Island and Farquhar Atoll sit in waters known for giant trevally and marlin.

A common mistake is assuming all islands offer the same fishing. The inner granitic islands support abundant reef life — bonefish, snapper, trevally — in protected bays. The outer atolls, particularly Cosmoledo and Astove, sit on the edge of deep drop-offs where pelagic species congregate. The difference isn’t just about fish size; it’s about the type of fishing you’ll actually be doing.

Where to Cast: Top Islands and Their Fishing Styles

Mahé: The Charter Hub

Mahé Island’s west coast, particularly around Port Launay and Beau Vallon, shelters the most charter operations in the country. Half-day trips typically run from 7 a.m. to noon, targeting yellowfin tuna and dorado (mahi-mahi) on trolled lures. The offshore waters beyond the reef hold wahoo and sailfish during the dry season. Expect to share the water with other boats — this is the busiest fishing zone in Seychelles. Most charters practice catch-and-release for billfish while keeping one or two fish for the crew and guests.

Cousine Island: Shoreline to Deep-Sea in One Day

Cousine Island hosts only a handful of guests at a time, which changes the fishing experience entirely. The shoreline fishing here involves standing barefoot on powder-soft sand at dawn or dusk, casting light tackle into the shallows. Local guides teach traditional hand-line techniques and help novices read the tides. When a fish is landed, it becomes part of the island’s catch-to-table ethos — grilled with local spices, simmered into a coconut curry, or served sashimi-style. For bigger game, the island arranges deep-sea charters that venture beyond the reef, often yielding yellowfin tuna, dorado, wahoo, marlin and sailfish.

Denis Island and Farquhar Atoll: Remote Big-Game Grounds

Denis Island sits on a coral bank roughly 100 kilometres north of Mahé, putting it closer to pelagic migration routes. The waters here hold giant trevally and marlin, and the island’s fishing charters target these species almost exclusively. Farquhar Atoll, part of the outer island group, offers similar conditions with even fewer boats. Both locations require internal flights or extended boat transfers, which adds significantly to trip cost and planning complexity. The trade-off is fishing pressure that’s a fraction of what you’ll find around the inner islands.

Practical Planning: Seasons, Costs, and Local Friction

Fishing in Seychelles is possible year-round, but the experience shifts with the trade winds and the species calendar. Here’s what that actually means for your trip.

Getting There and Getting on the Water

Most international flights arrive at Mahé International Airport. From there, inter-island flights connect to Praslin, Denis Island, and the outer atolls. Charter companies on Mahé and Praslin offer half-day and full-day trips, with prices varying by boat size and target species. On Cousine Island, fishing is included in the stay but deep-sea charters incur an additional fee. For the outer atolls like Farquhar and Cosmoledo, expect to book a multi-day package that includes accommodation, meals, and guided fishing.

Conservation Rules You Can’t Ignore

Seychelles enforces catch limits and protects certain species. Many charters practice catch-and-release for billfish, and guides encourage ethical practices such as using circle hooks to reduce by-catch and avoiding sensitive spawning grounds. On Cousine Island, activities follow an eco-calendar that respects nesting seasons of seabirds and turtles, aligning fishing with periods of abundance. These rules aren’t suggestions — they’re enforced, and anglers who ignore them risk fines or losing their charter access.

On the Ground: Packing, Etiquette, and What to Expect

Gear and What to Bring

Charter boats supply heavy rods and sturdy reels for deep-sea fishing, so you don’t need to bring your own offshore gear unless you have a specific preference. For shoreline fishing, light tackle and lures are useful, but local guides provide hand-lines and bait. What you do need: reef-safe sunscreen, a wide-brimmed hat, polarized sunglasses to cut through the surface glare, and a dry bag for electronics. The sun here is intense even on overcast days, and the reflection off the water amplifies exposure significantly.

Local Etiquette and Cultural Nuances

Seychellois fishing culture is rooted in subsistence and community. When a local guide teaches you hand-line techniques, they’re sharing knowledge passed down through generations. Respect that by listening more than you talk. On Cousine Island, the catch-to-table ethos means the fish you land becomes part of a shared meal — it’s considered poor form to waste what you catch. Tipping is customary for charter crews, typically 10–15% of the trip cost.

Seychelles Fishing: Your Questions Answered

Do I need a fishing license in Seychelles?

For recreational fishing on charter boats, the license is typically included in the trip cost. Shoreline fishing from beaches doesn’t require a separate permit, but catch limits still apply. Always confirm with your charter operator before heading out.

What’s the best island for beginners?

Mahé offers the widest range of charter options and the most forgiving conditions for first-time anglers. The protected bays on the west coast keep seas calm during the north-west monsoon, and guides are accustomed to teaching novices how to handle rods and reels.

Can I keep the fish I catch?

Yes, within limits. Most charters allow you to keep one or two fish for the boat’s crew and guests. Billfish are typically released. On private islands like Cousine, the catch goes directly to the kitchen for that evening’s meal — nothing goes to waste.

Is fishing worth it during the windy season?

It depends on what you’re after. Offshore charters become less reliable from May to September, but reef and surf fishing actually improve. The rougher water pushes baitfish closer to shore, which draws in predators like trevally and snapper. If you’re happy casting from the beach, the windy season can be excellent.

What’s the biggest downside to fishing in Seychelles?

The cost. Charter trips are expensive compared to other Indian Ocean destinations, and accessing the outer islands requires internal flights that add hundreds of dollars per person. The fishing is world-class, but it comes at a premium that not every budget can absorb.

One Last Thing

The thing that sticks with me about fishing in Seychelles isn’t the size of the fish — it’s how the whole day folds into something else. You start on the beach at dawn, end up sharing a meal built from what you caught, and somewhere in between you realise the boat traffic and the planning headaches were worth it. For a deeper look at what else the islands offer, Seychelles water sports beyond fishing covers snorkelling, kayaking, and the kinds of days that fill the gaps between charters.
