The Seychelles Outer Islands host one of the most diverse and powerful fisheries on the planet, filled with our target species. From shallow lagoon flats to deep offshore banks and sheer reef drop-offs, these remote atolls support an extraordinary range of species — many of them larger, more aggressive, and less pressured than anywhere else in the Indian Ocean.

This guide is designed as a comprehensive resource for anglers planning an Outer Islands expedition. It covers the main fish species encountered, how they are typically targeted, when they are most active, and what makes these waters so unique.

Why the Outer Islands Fishery Is Different

• Unlike coastal or heavily fished destinations, the Outer Islands remain vast, remote, and lightly pressured.
• Key factors that shape the fishery:
• Huge distances between islands and banks
• Minimal commercial fishing activity
• Strong, consistent ocean currents
• Healthy bait populations across all depth zones
• The result is a fishery where predators behave naturally, grow large, and feed aggressively.

Primary Target Species

Giant Trevally (GT) & Trevally Species

• Trevally, a big player in our target species, dominate the inshore and reef-edge environments of the Outer Islands and are among the most sought-after sportfish globally.
• Key species:
• Giant Trevally (GT)
• Bluefin Trevally
• Bigeye Trevally

Typical environments:

• Reef passes and whitewater edges
• Lagoon flats and shallow reef
• Drop-offs adjacent to structure

Techniques:

• Popping and stickbait casting
• Jigging around bommies and edges
• Sight-fishing on the flats

Seasonality:

Present year-round, with peak aggression from October to May, especially around spring tides.

GTs in the Outer Islands are larger, less cautious, and brutally powerful compared to pressured destinations.

Tuna Species (Yellowfin, Dogtooth & More)

Tuna are a cornerstone of the Outer Islands bluewater fishery, providing both relentless action and true test-piece fights.

Common species:

• Yellowfin Tuna
• Dogtooth Tuna
• Skipjack & other pelagics

Typical environments:

• Offshore banks (African Banks, Owen Bank)
• Current lines and bait balls
• Drop-offs and deep edges

Techniques:

• High-speed jigging
• Trolling (lures and baits)
• Casting into surface feeds

Seasonality:

• Strong numbers from February to May, with Yellowfin present most of the year.
• Dogtooth Tuna in the Outer Islands are especially destructive, testing gear, knots, and angler discipline.

Sailfish & Billfish

Sailfish are a regular and exciting presence in Seychelles waters, often appearing unexpectedly while targeting other species.

Typical environments:

• Offshore banks
• Temperature breaks
• Bait-rich current lines

Techniques:

• Trolling teasers and pitch baits
• Skipping ballyhoo
• Casting stickbaits to free-jumpers

Seasonality:

• Peak from October to December, with good numbers February to April.
• Encounters often include doubles or triples during peak conditions.

Reef Fish & Bottom Species

Reef fish form the backbone of the Outer Islands ecosystem and provide consistent action across a wide range of depths.

Key species:

• Jobfish
• Groupers (multiple species)
• Ruby Snapper
• Amberjack

Typical environments:

• Deep reef systems
• Channels and drop-offs
• Isolated bommies

Techniques:

• Bottom jigging
• Slow pitch jigging
• Deep dropping (manual or electric)
• Livebaiting for large Grouper

Seasonality:

• Available year-round, best in light winds and stable currents.
• Every drop can produce something different, making reef fishing highly engaging.

Barracuda

Fast, aggressive, and visually spectacular, Barracuda are common throughout the Outer Islands.

Typical environments:

• Shallow reef edges
• Channels and passes
• Sand-to-coral transitions

Techniques:

• Fast-retrieved stickbaits and poppers
• Trolling diving plugs
• Jigging near structure

Seasonality:

• Year-round, more active in warm, clear water.
• Strikes are violent and often occur at full speed.

Typical Fishing Scenarios in the Outer Islands

A single day can involve multiple fisheries:

• Popping reef edges for GTs at first light
• Switching to jigging for Dogtooth as current builds
• Trolling between spots and encountering Sailfish or Wahoo
• Deep dropping in the afternoon for reef species

This diversity is what makes Outer Islands trips uniquely rewarding.

Responsible Handling & Conservation

Sustainable fishing practices are essential to maintaining this fishery.

Key principles:

• Use tackle heavy enough to shorten fights
• Minimise air exposure for photos
• Support fish properly during handling
• Release large breeders wherever possible
• Respect local regulations and protected areas
• Healthy fish stocks are the reason the Outer Islands remain exceptional.

Planning Your Outer Islands Species Strategy
