One of the most ancient travel route, home to some of the most mysterious peoples, a volcanic basin that was isolated from the rest of the oceans during the last Ice Age, the Andaman Sea is a tropical paradise brimming with crystal-clear waters, vibrant marine life, and pristine fishing opportunities. Whether you’re an experienced angler or someone looking to try your hand at fishing for the first time, this lesser-known gem offers something for every fisherman.

The Andaman Sea at a Glance

The Andaman Sea is part of the northeastern Indian Ocean, bounded by the coasts of Myanmar, Thailand, and the Andaman and Nicobar Islands. It covers approximately 600,000 square kilometers, with depths reaching up to 4,198 meters in the Nicobar Trough. What sets the Andaman Sea apart from other fishing destinations is the remarkable biodiversity and the sheer variety of fishing experiences it offers. From deep-sea fishing in the open ocean to relaxed nearshore fishing around the countless islands, the possibilities are endless.

The Andaman Sea has a fascinating volcanic origin. The sea sits on a tectonic boundary between the Indian and Burma plates, making it part of a highly active seismic zone. One of the most amazing but rarely mentioned features of the Andaman Sea is the Barren Island, India’s only active volcano, located about 135 kilometers northeast of Port Blair in the Andaman Islands. The volcano rises out of the sea and, though largely quiet, it occasionally erupts, offering visitors a rare glimpse of a natural wonder in an otherwise tranquil fishing paradise. This unique geological backdrop adds another layer of intrigue to the already adventurous experience of fishing in the Andaman Sea.

Large-scale commercial fishing has been banned in the Andaman Sea several years ago, which had a most favorable effect on fish populations, and catch-and-release is the norm for marlin and other iconic game fish. Warm year-round, with water temperatures ranging between 26°C (79°F) to 30°C (86°F), the Andaman Sea is a haven for both fish and fishermen alike. The dry season (November to April) is considered the best time for fishing, as the sea remains calm and the skies clear.

Fish of the Andaman Sea

One of the most exciting aspects of fishing in the Andaman Sea is the sheer diversity of species that call these waters home. Whether you’re casting your line nearshore or heading out to the deep sea, you’ll have the chance to hook some incredible game fish.

Giant Trevally (GT)

Known as the “gangster of the reef,” the giant trevally is a top target for anglers in the Andaman Sea. Famous for their aggressive strikes and powerful fights, these fish are a challenge even for the most seasoned fishermen. They’re found near rocky outcrops and reefs, and popping or jigging are the best methods to lure these reef predators.

Yellowfin Tuna

One of the ocean’s fastest and most formidable fighters, the yellowfin tuna is a prize catch for deep-sea anglers. These fish are known for their explosive runs and stamina, often giving fishermen a workout they won’t soon forget. You can find them in the deeper waters, particularly around drop-offs and underwater seamounts.

Dogtooth Tuna

A local favorite in the Andaman Sea, the dogtooth tuna is known for its brute strength. Often found near reefs and drop-offs, this species is highly sought after by anglers for both sport and table fare.

Sailfish

If you’re after a high-flying, acrobatic fish, sailfish should be on your list. These beautiful, fast swimmers are common in the Andaman Sea and are particularly abundant during the warmer months. Trolling with live bait or lures is the preferred method for hooking these majestic fish.

Marlin

The Marlin magazine called the Andaman Sea one of the few unexplored hotspots for billfish that truly deserves the name. Some charters report of 300 lb+ marlin caught causally during the crossing from Phuket. Both blue and black marlin are there, giving an opportunity for the Grand Slam of the Indian Ocean: blue, black marlin and sailfish in one trip.

Other Species

In addition to these stars, the Andaman Sea is home to a plethora of other game fish such as wahoo, barracuda, snapper, and various types of grouper. Whether you’re bottom fishing or trolling offshore, you’re sure to encounter a wide variety of species.

Fishing Hotspots in the Andaman Sea

The Andaman Sea’s coastline is dotted with numerous islands and fishing hubs, each offering unique opportunities for anglers.

Phuket, Thailand

A popular tourist destination, Phuket is also a top spot for fishing in the Andaman Sea. You can embark on both inshore and offshore fishing trips from here. The nearby Similan and Surin Islands are particularly known for big game fishing, with yellowfin tuna, marlin, and sailfish commonly caught.

Koh Lanta, Thailand

Koh Lanta provides a quieter, more laid-back fishing experience compared to Phuket. However, the waters here are still teeming with GTs, barracuda, and king mackerel, making it a great spot for both inshore and offshore fishing.

Andaman Islands, India

A more remote destination, the Andaman Islands offer some of the best fishing experiences in the region. These islands are home to some of the largest GTs in the world, with catches often exceeding 50 kg (110 lbs). Popping and jigging for these giants is a popular technique. The deep waters surrounding the islands are also great for dogtooth tuna and yellowfin tuna fishing.

The islands of the Andaman Sea are an amazing destination. Some of them are home to human populations that might have descended directly from the first Homo Sapiens who left Africa many thousand years ago, and still live the primitive lifestyle, avoiding all contact with the outside world. These islands are totally closed for tourists, and you need a permit from the Government of India to visit the archipelago in the first place. The permit is not difficult to obtain, but the Andaman and Nicobar Islands aren’t easy to reach, requiring either a connecting flight or a long sea crossing from Thailand or Myanmar ports. 

Fishing Techniques and Tips

Fishing in the Andaman Sea offers a variety of techniques depending on your target species and location. Here are some of the most common:

Popping and Jigging

When fishing for giant trevally or dogtooth tuna, popping and jigging are the go-to methods. The key is to use strong, durable tackle, as these fish are known for their fierce fights and can easily break lighter gear.

Trolling

For targeting pelagic species like sailfish, marlin, and tuna, trolling with live bait or lures is highly effective. You’ll want to troll around drop-offs and underwater structures where these fish tend to congregate.

Bottom Fishing

If you’re after groupers, snappers, or other reef-dwelling fish, bottom fishing is your best bet. This technique works particularly well around the many reefs and wrecks scattered throughout the Andaman Sea.

Fly Fishing

While not as common as other techniques, saltwater fly fishing can be incredibly rewarding in the Andaman Sea, especially in the shallow flats around the islands. Species like bonefish, permit, and trevally can be caught using fly rods, providing a thrilling challenge for any angler.

Best Time to Fish in the Andaman Sea

While the Andaman Sea is a year-round fishing destination, the best time to visit is during the dry season from November to April. The weather is calmer, and the fish are more active, making it easier to target both inshore and offshore species. However, even during the monsoon season (May to October), you can still find plenty of fishing opportunities in sheltered areas near the islands.

Conclusion

If you’re visiting Thailand for a beach vacation with your family, why not add a fishing trip to your itinerary? Many fishing charters around Phuket and Koh Lanta offer half-day or full-day excursions that are perfect for beginners and families. You can experience the thrill of reeling in a big fish while soaking in the stunning coastal views. Most trips include all the necessary gear, and experienced captains will ensure everyone has a great time, whether you’re trying your hand at fishing for the first time or just looking for a fun activity with the kids. After a relaxing day on the beach, an afternoon on the water can be a refreshing change of pace—plus, the kids will love the excitement of catching their own dinner!

Fishing in the Andaman Sea is more than just a pastime; it’s an adventure.

First things first: Macaronesia is not a misspelling of Micronesia. Micronesia is the northwestern part of Oceania, with some 200 Pacific islands including the Marshall Islands and Guam. Macaronesia, by contrast, refers to several archipelagos lying in the Eastern Atlantic: the Canary Islands, Cape Verde, Madeira, and the Azores. The term “Macaronesia” was originally coined in Ancient Greece, and literally means “Islands of the Fortunate”. As long as recreational angling is concerned, the ancient Greeks had it spot on.
