Dogtooth Tuna Fishing in the Maldives
Named for their prominent, dog-like teeth, Dogtooth Tuna are powerful predators that inhabit the deeper reef slopes and drop-offs around Maldivian atolls. They're known for their incredible fighting ability and tendency to dive deep when hooked. These solitary hunters are prized catches for experienced anglers using jigging techniques.

Why the Maldives for Dogtooth Tuna
Dogtooth tuna inhabit the deeper reef slopes and drop-offs around Maldivian atolls — exactly the kind of structure found along Gaafu Atoll's outer reef, where Emperor's jigging trips run.

Dogtooth Tuna: the Reef's Toughest Fighter
Dogtooth tuna (Gymnosarda unicolor) are named for their sharp, conical teeth, unusual among tunas. Unlike yellowfin and skipjack, which roam the open ocean in schools, dogtooth tuna are reef predators that live along deep reef walls and drop-offs, usually alone or in small groups. They grow up to about 130 cm and 70 kg.
Dogtooth are famous for their strength. When hooked, a dogtooth turns and dives straight for the reef, and if it gets there, the line is usually cut on the coral. Landing one takes heavy tackle, a tight drag and quick, determined winding in the first seconds of the fight, which is exactly why jigging anglers travel to catch them.
Where to Find Dogtooth Tuna in the Maldives
Dogtooth tuna hold on the steep outer reef walls where the coral falls away into deep water, at the drop-offs at channel mouths, and around deep pinnacles. They feed where current pushes bait along the wall, so the best spots are on the up-current side of the reef while the tide is running.
The remote southern atolls are among the best places in the Maldives for dogtooth tuna, because their outer walls see very little fishing pressure. Gaafu Alifu, where our boat Emperor is based, has a long outer reef with deep walls and channel drop-offs close to the island of Maamendhoo.
How to Catch Dogtooth Tuna: Jigging
Jigging is the main way to catch dogtooth tuna. A heavy metal jig is dropped down the reef wall to the depth where the fish are holding, then worked back up with sharp lifts of the rod and fast turns of the reel. The strike often comes as the jig falls or on the first lifts off the bottom, so stay ready from the moment the jig hits the depth.
Speed jigging, with fast, aggressive lifts and long slim jigs, is the classic dogtooth technique. Slow-pitch jigging, with shorter lifts and flatter jigs that flutter as they fall, also catches dogtooth and brings groupers, snappers and amberjack too. Dogtooth tuna occasionally take poppers when they come up to the surface, and are sometimes caught on live bait.
Dogtooth Tuna Jigging Tackle
Dogtooth tackle has to stop a powerful fish within a few metres of the reef. Anglers use a strong jigging rod and a high-capacity spinning or overhead jigging reel with a powerful drag, braided main line for direct contact with the jig, and a thick fluorocarbon leader to resist the teeth and the coral. Jigs range from around 100 g to 300 g or more, depending on the depth and current, rigged with strong assist hooks.
On Emperor, basic fishing gear is included on every charter, and you can add a professional jigging rod and reel setup for USD 80 per setup if you don't bring your own.
How to Fight a Dogtooth Tuna
Set your drag tight before you drop the jig. When a dogtooth hits, don't give it line: lock the rod against your body, lift and wind hard to pull the fish up and away from the reef in the first few seconds. Once it is clear of the wall, keep steady pressure and pump and wind to the surface. Fighting from a moving boat helps: the captain will often motor away from the reef to drag the fish into open water.
Dogtooth Tuna Fishing Charters and Prices
Emperor is a 32-foot boat with twin 200 HP engines for up to 5 anglers. A full-day charter costs USD 1,380 per boat and a half day USD 980, including the captain and crew, fuel, soft drinks and snacks, and basic gear. The crew plans jigging sessions on the reef walls around the tide, and can mix in popping for giant trevally and trolling for tuna and wahoo.
For several days of jigging, our packages at the Maldives Fishing and Holidays Lodge on Maamendhoo include the lodge, full-board meals, the domestic flight, the boat transfer and a private charter on every fishing day:
Other Fish You Catch Jigging for Dogtooth Tuna
Jigging the deep reef walls rarely produces only dogtooth tuna. The same jigs catch giant trevally holding deep, amberjack, groupers such as the spotted and coral groupers, red snappers, jobfish and other reef fish, many of them excellent to eat. Slow-pitch jigging in particular brings a wide mix of bottom species, which makes a jigging session productive even on days when the dogtooth aren't biting.
Because the reef walls sit right beside the channel mouths, the crew can also switch to popping for giant trevally when the tide runs, or head offshore to troll for yellowfin tuna and wahoo.
Dogtooth Tuna Catch and Release
Dogtooth tuna are slow-growing reef predators, and many anglers release them. Keep the fight short with strong tackle, handle the fish carefully away from its teeth, support its weight for a quick photo, and revive it in the water before letting go. If you keep one for the table, dogtooth makes excellent eating.
