Tuna

Category: Offshore

Trip Type: Offshore / Deep Offshore

Louisiana's offshore waters host some of the finest tuna fishing in the world, with multiple species offering world-class action and outstanding table fare year-round.

Appearance

Louisiana waters are home to several tuna species, each with its own distinctive profile. Yellowfin tuna are the most commonly targeted, with their bright yellow fins and golden lateral stripe making them instantly recognizable. Blackfin tuna are smaller and darker with a bronze lateral stripe. Bluefin tuna are massive, dark-backed fish capable of exceeding 1,000 pounds. Bigeye tuna are powerful deep-water fish with notably large eyes. All tuna share a torpedo-shaped body, crescent tail, and streamlined build designed for speed and endurance.

Habitat

Tuna are found in the open offshore and deep offshore waters of the Gulf of Mexico. Yellowfin and blackfin are the most accessible species and are commonly encountered around oil platforms, offshore lumps, current breaks, and floating structure. Bluefin and bigeye tuna inhabit deeper waters and are associated with the Mississippi Canyon and other deep-water structure south of the Louisiana coast.

Average Size

Size varies dramatically by species. Blackfin tuna typically weigh 5 to 25 pounds. Yellowfin commonly run 40 to 150 pounds with giants exceeding 200 pounds. Bigeye tuna can exceed 300 pounds and bluefin can top 1,000 pounds.

Best Time to Catch

Tuna can be caught year-round in Louisiana's offshore waters. Winter is particularly famous for giant yellowfin around offshore lumps, while spring, summer, and fall offer consistent opportunities across multiple species.

Fishing Tips

Louisiana's famous offshore lumps — including the Midnight Lump near the Mississippi Canyon — are among the best yellowfin tuna grounds in the world. Live bait, chunking, trolling, and kite fishing are all effective techniques depending on conditions. Blackfin are commonly caught around nearshore platforms on smaller lures and jigs. Winter often produces the largest yellowfin of the year around deep offshore structure.

Louisiana State Record

Louisiana holds impressive state records across multiple tuna species, headlined by a 251-pound yellowfin tuna caught by Elliot Sale in 2012 and a 1,152-pound bluefin tuna caught by Ron Roland in 2003 — two of the most remarkable tuna catches in Gulf history.

Fun Fact

Louisiana's offshore lumps — underwater topographic features rising from the Gulf floor — concentrate baitfish and create some of the most productive tuna fishing grounds in the entire Gulf of Mexico, drawing anglers from across the country each winter.
