Yellowfin Tuna

Category: Deep Offshore

Trip Type: Deep Offshore

Yellowfin tuna are the cornerstone of Louisiana offshore fishing, combining incredible strength, world-class table fare, and year-round opportunities.

Appearance

Yellowfin tuna are powerful, torpedo-shaped fish with dark metallic blue backs that fade to silver and gold along their sides and belly. Their most recognizable features are their bright yellow dorsal and anal fins, along with a row of vivid yellow finlets running toward the tail. Large yellowfin often develop long, sickle-shaped fins that make them one of the most striking fish in the Gulf.

Habitat

Yellowfin tuna are found in deep offshore waters throughout the Gulf of Mexico. They are highly migratory and often gather around underwater structures known as 'lumps,' as well as offshore oil platforms, rigs, current breaks, and areas with abundant baitfish. Louisiana’s offshore waters, particularly around the Mississippi Canyon and Midnight Lump, are famous worldwide for producing giant yellowfin tuna.

Average Size

Most yellowfin tuna caught in Louisiana waters weigh between 40 and 100 pounds, although fish exceeding 150 pounds are common in productive offshore areas. Trophy fish can surpass 200 pounds.

Best Time to Catch

Yellowfin tuna can be caught year-round in Louisiana, but winter is particularly famous for producing large fish around offshore lumps and deep-water structure. Spring and fall also provide excellent fishing opportunities.

Fishing Tips

The famous offshore 'lumps' of the northern Gulf are among the most productive locations for yellowfin tuna. Midnight Lump, located south of the Mississippi River Delta near the Mississippi Canyon, is one of Louisiana’s best-known yellowfin hotspots. Live bait, chunking, trolling, and kite fishing can all be effective techniques. Winter often produces some of the largest fish of the year.

Louisiana State Record

251 pounds — caught by Elliot Sale in 2012. This massive fish remains Louisiana’s state-record yellowfin tuna and highlights why Louisiana is considered one of the world’s premier destinations for giant yellowfin fishing.

Fun Fact

Yellowfin tuna are capable of swimming at speeds exceeding 40 mph and can travel hundreds of miles during their migrations through the Gulf of Mexico.
