There are fish you chase for meat, and there are fish you chase for meaning.

In the Seychelles, marlin fall squarely in the second category.

If you’ve spent time along the Drop Off — that dramatic oceanic ledge where the plateau plunges from 75 meters to abyssal depths — you know the feeling. The first greyhounding run across indigo water, the bill slashing through tropical swells, the realization that you’re connected to something wild and ancient in one of the world’s most pristine fisheries.

That’s exactly why how we fish for marlin in these waters matters just as much as whether we do.

Ethical marlin fishing isn’t about rules on paper. It’s about respect, restraint, and making decisions that ensure these fish are still tearing up Indian Ocean blue water long after our reels go quiet.

Why Ethical Practices Matter in Seychelles Waters

Marlin are apex predators with slow growth rates and late maturation, playing a critical role in open-ocean ecosystems. In the Indian Ocean, blue marlin populations face mounting pressure, while black marlin — the species that draws anglers from around the world to our waters — requires careful stewardship.

The Seychelles has undergone a remarkable transformation, shifting from “kill every billfish” to comprehensive tag-and-release programs in just a few years. The Seychelles Sports Fishing Club now tags over 800 billfish annually, contributing vital data to conservation efforts across the Indian Ocean.

Poor handling, extended fight times, and unnecessary harvest can have long-term consequences — even when the fish swims away. If we want our grandchildren to experience what we have in these waters, it starts with smarter decisions today.

The Seychelles Conservation Movement

Since partnering with organizations like The Billfish Foundation, WWF, and IFREMER, the Seychelles has deployed everything from standard tags to expensive satellite tags on blue and black marlin. This isn’t just data collection — it’s a commitment to understanding and protecting the species that define our fishery.

Denis Island’s fishing teams have received more conservation Tag & Release awards from The Billfish Foundation than any other resort in the Indian Ocean, proving that world-class fishing and conservation aren’t mutually exclusive — they’re inseparable.

1. Fight the Fish Hard — and End It Quickly

This one sounds counterintuitive, but it’s foundational in our tropical waters.

A long, drawn-out fight isn’t noble — it’s dangerous. In the warm Indian Ocean, lactic acid builds up quickly in exhausted fish, dramatically reducing survival rates.

Best practices for Seychelles conditions:

  • Use appropriate tackle for the species you’re targeting. Black marlin on the plateau can be fought on slightly lighter gear than blues over deep water, but always err on the side of caution
  • Apply steady drag pressure instead of playing the fish to exhaustion
  • In water temperatures averaging 27-29°C (80-84°F), shorter fights are even more critical than in cooler fisheries
  • Remember: the Drop Off is 10-60 miles from most marinas. A fish that needs extended revival time in these conditions faces additional stress

You’re not proving toughness by dragging it out. You’re proving skill by ending it efficiently.

2. Choose Gear That Helps the Fish Live

Ethical marlin fishing starts before you leave Eden Island Marina, Denis Island, or wherever you’re based.

Circle hooks are mandatory for responsible fishing in Seychelles:

  • They reduce deep hooking dramatically
  • They increase jaw hookups, making release safer and faster
  • They’re easier and faster to remove in tropical heat
  • Many Seychelles charter operations won’t fish with anything else

Avoid light-wire hooks that straighten under pressure or J-hooks that increase gut-hooking risk. The Seychelles Sports Fishing Club standards are clear: conservation-grade tackle isn’t optional — it’s the baseline.

3. Keep the Fish in the Water

If there’s one rule that should never be broken in Seychelles waters, it’s this:

A marlin does not belong on the deck.

No exceptions. Not for photos. Not for “a quick measurement.” Not ever.

  • No gaffs for release fish
  • No dragging over gunwales
  • No dry decks, no hot fiberglass
  • Control the fish boatside, remove the hook cleanly, and let it swim off under its own power

If you need photos, take them in the water, quickly, with the fish upright and supported. The Seychelles sun is brutal — every second a marlin spends out of water in our climate is a second closer to mortality.

Protected zones immediately surrounding islands like Denis have been established where fishing is strictly prohibited, recognizing that habitat protection complements ethical practices.

4. Proper Handling Makes the Difference

When handling is unavoidable along the Drop Off or plateau edges:

  • Never grab the bill and force the head sideways — this can damage the marlin’s sensitive rostrum
  • Support the body if touching the fish
  • Avoid the eyes and gills entirely
  • Use dehookers or bolt cutters when needed — a cut hook is better than a dead fish
  • Work quickly in the equatorial sun. Every second counts

The Seychelles fishing community has developed specific techniques for working billfish in tropical conditions. Learn from experienced captains who’ve perfected these methods over decades.

5. Revive Until It’s Ready — Not When You Are

A released marlin should leave strong, upright, and kicking — not rolled or struggling.

Revival techniques refined in Seychelles waters:

  • Idle forward to push water across the gills
  • Keep the fish straight — no towing sideways
  • In the warm Indian Ocean, revival may take longer than in cooler waters. Be patient
  • Watch for strong tail beats and coordinated swimming before letting go
  • If the fish sinks or rolls, you let go too soon

With satellite tagging programs revealing that tagged fish either circle the Seychelles or migrate to distant waters, proper revival isn’t just about immediate survival — it’s about ensuring these fish can complete their migratory patterns and contribute to the broader Indian Ocean population.

6. Kill Selectively, Not Habitually

There are times and places where harvesting a marlin is legal and culturally appropriate in Seychelles. The archipelago has a rich fishing heritage, and sustainable harvest has its place.

If considering keeping a fish:

  • Do we need this fish for food or cultural purposes?
  • Can we use it responsibly? (Many Seychelles resorts feature guest catches in their sea-to-table dining programs)
  • Is this the right moment, or are we killing automatically?

Denis Island’s restaurant showcases guest catches in their eagerly anticipated Japanese night, featuring ocean-fresh sushi and sashimi, demonstrating that selective harvest can align with conservation when done thoughtfully.

Keeping one fish intentionally is different from killing one automatically. The Seychelles Sports Fishing Club’s conservation league demonstrates that you can have both — selective harvest for food alongside robust tag-and-release programs.

The Seychelles Difference: Where Conservation Meets World-Class Fishing

Few places on earth offer as good a shot at completing the coveted IGFA Royal Slam — catching all species of billfish worldwide — as Seychelles, where black marlin, blue marlin, sailfish, and increasingly swordfish are all present.

Our waters host marlin year-round, with prime conditions during the calmer periods of March-April and October-November, and peak action from September to November. This isn’t a seasonal fishery that disappears — it’s a permanent ecosystem requiring permanent stewardship.

What makes Seychelles special:

  • The Drop Off brings deep water within 10-15 minutes of islands like Denis, rather than the hour-plus runs from Mahé
  • The plateau’s unique structure, nowhere deeper than 75 meters, attracts black marlin that prefer shallower water
  • An untapped fishery where regular 500-pound marlin are still possible
  • A community that has embraced conservation as essential, not optional

The Real Trophy Is Watching It Swim Away

Anyone can post a grip-and-grin.

Not everyone earns the quiet satisfaction of watching a marlin fade back into Indian Ocean blue water — healthy, powerful, and free.

That moment is the true reward. It’s the kind of fishing that keeps the sport honest and the ocean alive.

Having shifted the entire mentality in just a few years is remarkable, but maintaining it requires every angler who fishes these waters to uphold the same standard.

If you believe in fishing this way — hard, clean, and respectful — you’re our kind of angler.
