Deep Sea Fishing in Andaman: A Pro-Guide to Catching Giant Trevally (GT) and Tuna (2026)

Let’s be honest: you aren’t here for "sightseeing." You aren't here for a relaxing boat ride with a cold drink and a light breeze. You’re here for the Thrill. In the world of sport fishing, there is nothing that tests your gear, your strength, and your sanity quite like an Andaman Giant Trevally (GT) hitting a surface popper. It’s not a bite; it’s an explosion. And if you’re targeting Dogtooth Tuna, you better hope your drag is set tight and your back is strong, because they’ll try to pull you straight into the reef before you even know you’ve hooked one.

Andaman is widely considered one of the last "untamed" frontiers for game fishing in Asia. But because it’s raw, it requires a "Pro" approach. If you show up with freshwater tackle and a "let's see what happens" attitude, the sea will send you home with nothing but broken line and a bruised ego.

Let’s get your gear in order.

1. The Target List: GT vs. The "Dogs" of the Deep

• Giant Trevally (GT): The "King of the Reef." These guys hunt in the shallows and around drop-offs. They are aggressive, territorial, and will smash a surface popper with absolute hatred. Expect a brutal, high-intensity tug-of-war.

• Dogtooth Tuna: These aren't your average tuna. They stay deep, hunt near the reefs, and are famous for their "first run"—a lightning-fast dash to the bottom that can snap even 100lb braid if you aren't careful.

• Yellowfin Tuna & Billfish: For the trollers, the deep blue waters offshore hold massive Yellowfin and the occasional Marlin or Sailfish.

2. The Battlegrounds: Havelock, Barren Island, and the Banks

• Havelock (Swaraj Dweep): The perfect launchpad. Surrounded by vibrant reefs and deep channels, it offers world-class popping and jigging right in its backyard.

• Barren Island: The ultimate "Holy Grail." India’s only active volcano is surrounded by deep, nutrient-rich volcanic waters that attract the biggest GTs and Tuna in the archipelago. It’s a 10-hour round trip, but it’s worth every second.

• Invisible Bank: A remote, submerged plateau in the middle of the Andaman Sea. It’s legendary among pro-anglers for its sheer biodiversity and the size of the predators that call it home.

3. The Pro-Tackle: Don't Bring a Knife to a Gunfight

If you're serious, you need serious gear.

• Popping: Use 8-foot heavy-duty rods and high-speed reels (like a Shimano Stella or Daiwa Saltiga). You need at least PE 8-10 braid and 170lb–220lb shock leaders.

• Lures: Large "cup-faced" poppers (120g–200g) are the way to go. The louder the "pop," the more likely a GT is to come up from the depths to investigate.

• Catch & Release: Most reputable charters in the Andamans follow a strict Catch-and-Release policy to ensure the fishery remains world-class for generations.

4. Permits & Logistics: The Boring (but Essential) Stuff

You can't just throw a line into the water.

• The Permit: Sport fishing permits are mandatory. For 2026, the fee is approximately ₹500 for Indian nationals and ₹2,500–₹2,900 for foreigners per day. Most charters will handle this for you, but always check.

• Timing: The season runs from October to May. The peak "Big Fish" months are January to March, when the seas are glassy and visibility is perfect.

• Travel Stress: When you’re lugging expensive rods and tackle boxes, the last thing you want is a logistical nightmare. GoNautika.com helps you book the fastest ferries with instant seat selection, so you and your gear travel in air-conditioned comfort without the "will I get a ticket?" anxiety.
