Top Deep Sea Fishing Targets in Louisiana

Deep sea fishing in Louisiana means targeting some of the ocean’s biggest predators. Yellowfin Tuna are the main attraction, with White and Blue Marlin, Sailfish, and Wahoo also making waves. Meanwhile, night fishing for Swordfish is a popular choice for thrill-seekers. And let’s not forget bottom fishing, with a variety of Snappers and Groupers guaranteeing a feast for the senses. Here are the most popular catches in LA:

Who else could open our list of Louisiana’s deep sea superstars but the Snapper trio? Red, Lane, and Vermilion Snapper are among the most prized catches for their fighting abilities and meat qualities. Reds and Lane Snapper often hang out around reefs and oil rigs, while Vermilion Snapper add a splash of color to the deeper waters.

Bottom fishing is your best bet for landing Snapper. Head to the rigs and artificial reefs off the coast with heavy tackle and live bait like pilchards or squid. However, the best time to target Snapper in Louisiana varies. Red Snapper season typically opens in summer, providing a limited but exciting window. Lane and Vermilion, on the other hand, bite year-round, making them reliable targets whenever you venture out. Remember to check the latest regulations, as seasons can change based on conservation efforts.

Where there are Snapper in the Gulf, there are usually Grouper. Gag, Scamp, Black, Red, and Goliath Grouper are prized for their size, strength, and tasty meat. Gags and Reds often reach up to 50 pounds, while Black and Scamp can range from 10 to 30 pounds. But Goliath are the true giants—hence their name. They often exceed 400 pounds! 

You can target Black and Scamp Grouper year-round, but other species have peak times. Gag and Red Grouper are most active in the spring and fall, while Goliath Grouper are usually catch-and-release-only.

As with Snapper, bottom fishing is the way to go to land a Grouper. Heavy-duty bottom fishing setups with live or cut bait, such as mullet, squid, or crabs, are essential. Louisiana’s oil rigs, reefs, and wrecks are solid hunting grounds, but the big boys lurk in the depths. Check out the Mississippi and Green Canyons for oversized monsters.

Mahi Mahi

Mahi Mahi are true stars of the deep sea fishing world, and Louisiana is no exception. These fish are celebrated for their stunning appearance and acrobatics, and they also weigh in at a decent 10–50 pounds. The best time to fish for Mahi Mahi in Louisiana is from late spring through early fall, although the season can run longer. The warmer waters attract large numbers of Mahi Mahi, offering prime fishing opportunities.

Trolling with colorful lures or using live bait like ballyhoo is highly effective for catching Mahi Mahi. These gorgeous fish often hang out near floating debris and oil rigs in the Gulf. Look for them in the upper water column where they hunt and perform their impressive leaps.

Tuna

Onto a family of fish that needs no introduction. Tuna are known worldwide for their delicious taste. But Blackfin, Yellowfin, Bigeye, and Skipjack Tuna are also top fighters in Louisiana’s deep sea fishing realm. Yellowfin and Bigeye Tuna, in particular, shine, as they often exceed 100 pounds. 

Tuna fishing in Louisiana is a year-round affair. Bigeye Tuna never take a break, while Blackfin and Skipjack Tuna are most abundant from spring to early fall. The best months for Yellowfin Tuna are typically from November to May, giving you ample reason to visit LA in winter!

Trolling with lures or live bait such as sardines, as well as chunking with pieces of fish, are effective methods for enticing Tuna. You can find these fish near oil rigs and floating debris, with the Mississippi Canyon standing out as the most productive spot. For Yellowfin Tuna, nighttime chunking can be particularly productive, adding an extra layer of excitement to your trip.

Marlin

Next up are the majestic Blue and White Marlin—the crown jewels of Louisiana’s deep sea fishing scene. White Marlin typically range from 50 to 150 pounds, while Blue Marlin can weigh over a staggering 1,000 pounds! These spectacular fish are the epitome of sportfishing, with their speed, power, and leaping prowess. To make your angling dreams come true, visit in summer, as these fish bite best from spring through early fall. 

Trolling with heavy-duty gear is essential to have a shot at a Billfish. Use large lures or live bait like ballyhoo and mackerel to draw them in. The waters around the Mississippi Canyon and offshore oil rigs are great spots, where the continental shelf drops off into deeper waters. Just make sure you’re ready for a long and intense battle! 

Deep Sea Fishing Techniques in Louisiana 

We bet you’re already planning your deep sea fishing trip to Louisiana! But before you set off, it’s crucial to have the right techniques and gear lined up. Here’s a quick rundown of the most popular tactics and the essential equipment you’ll need for a successful deep sea fishing adventure:

Trolling

Trolling is one of the most effective deep sea fishing techniques, full stop. If you’re aiming to catch any fish that feeds near the water tops, this is your best bet. That means Marlin, Tuna, Mahi Mahi, and much more. 

In essence, trolling means dragging a line or more behind a boat. You can set up multiple rods and drag lures or bait through the water at varying depths. Your captain can use outriggers to spread the lines and downriggers to position the bait at the optimal depth. Expect a variety of rods, reels, and tackle at your disposal, with baits like squid, ballyhoo, mullet, and mackerel, along with a range of artificials. 

Bottom Fishing

Compared to trolling, bottom fishing is all about patience and precision. Since your boat will remain stationary, selecting the right spot is crucial. In the Gulf of Mexico, this often means targeting offshore oil rigs or artificial reefs. As the name implies, you’ll drop your bait close to the seafloor or structure and wait for hungry fish to bite. Heavy tackle and weights are essential to keep your bait steady in deep waters.

This technique is particularly effective for catching species like Grouper and Snapper that dwell near underwater structures. Using a fish finder to locate reefs and wrecks can significantly boost your success. While bottom fishing is straightforward, remember that you’ll be fishing along rugged terrain, which means the potential for broken lines and escaping fish. With practice, you’ll master the art and enjoy hauling in those big catches.

Deep Dropping

Simply put, deep dropping is bottom fishing in very deep waters. Unlike regular bottom fishing, it requires specialized equipment to be effective, as fishing at depths of over 600 feet is a whole different ballgame! Electric reels are essential unless you want to spend ages reeling in your line to change bait. 

The list of species you can target is similar to regular bottom fishing. However, the fish get much bigger the deeper you go. Plus, deep dropping offers a shot at prestige catches like Swordfish and Tilefish. Be prepared to spend some time offshore, but the potential rewards make it worth every minute.

Chunking

For those targeting Tuna, chunking is a highly effective method. This technique involves cutting fish into chunks and throwing them overboard to create a feeding frenzy. Yellowfin Tuna, in particular, respond well to this method. Toss chunks of fish like sardines or mullet overboard at different times, while keeping your lines baited with the same meat. This technique is especially effective around oil rigs and the nutrient-rich waters of the Mississippi Canyon, where Tuna love to prey. 

Louisiana Deep Sea Fishing Gear

Having the right gear is crucial for a successful Louisiana deep sea fishing trip. For trolling, you’ll need sturdy, high-capacity reels and heavy-duty rods. Bottom fishing requires heavy tackle, too, including strong rods and reels with high line capacity to manage deep drops and powerful fish. Electric reels are indispensable for deep dropping, making the process much more efficient.

When it comes to bait and lures, live baits like pilchards, mullet, ballyhoo, and blue runners are excellent for attracting a variety of game fish. Popular artificial lures include trolling plugs, skirted lures, jigs, and soft plastics. Circle hooks are effective for ensuring solid hook-ups and reducing deep hooking. All in all, you’ll want a bit of diversity in your arsenal!

Where to Go Deep Sea Fishing in Louisiana

You don’t have to travel far to find the best deep sea fisheries in Louisiana. From the renowned hub of Venice to various oil platforms, here’s a quick list of some top destinations:

  • Buras. Located near the Mississippi River, this spot offers quick access to the deep waters. It’s an excellent starting point for targeting a variety of pelagic species.
  • Flower Gardens. Situated 100 miles offshore, this is the only living coral reef in the western Gulf of Mexico. Home to over 300 species of fish, you can troll here for big game like Marlin and Tuna.
  • Venice. Famous for its proximity to deep waters, Venice offers access to the continental shelf just a short ride from the Mississippi River. This spot is ideal for big game fishing with depths reaching 1,000 feet quickly.
  • Grand Isle. Rivaling Venice in terms of its deep sea fishing offer, Grand Isle allows you to wet your line in deep waters just 12 miles from shore. Target Blue and White Marlin, Mahi Mahi, and Yellowfin Tuna here.
  • Midnight Lump. 50 miles out from Venice, this world-famous spot is a top feeding area for migrating Yellowfin and Blackfin Tuna. It’s a great place for trolling or vertical jigging for trophy fish like Marlin, Wahoo, and Amberjack, too. 
  • Oil Platforms. These structures create perfect habitats for multiple species. The Green and Mississippi Canyons are particularly productive for Marlin, Tuna, Wahoo, Mako Shark, Amberjack, and Mahi Mahi at depths of 1,000 feet.

When to Go Deep Sea Fishing in Louisiana 

While Louisiana offers year-round deep sea fishing opportunities, knowing the best times to target specific species can make all the difference.

In winter, cooler waters bring Yellowfin Tuna and Wahoo closer to shore, especially around structures like oil rigs. As spring warms up the seas, Mahi Mahi and Blackfin Tuna become more active, providing plenty of excitement for anglers.

Summer is fantastic for targeting Blue Marlin and even more Mahi Mahi, along with Bigeye and Skipjack Tuna. However, it’s wise to keep an eye on weather conditions, as storms can occasionally disrupt fishing plans. Come fall, Wahoo and various species of Grouper and Snapper take center stage. This period offers a diverse range of fishing opportunities, with many species being highly active and ready to bite. 

In short, Louisiana’s great weather and rich waters mean there’s always a game fish ready to challenge you. But we have one other tip—planning your trip around the full moon can also yield excellent results. 

Deep Sea Fishing Tournaments in Louisiana

If you’re interested in some competitive angling, Louisiana hosts several deep sea fishing tournaments that attract anglers from all over the country. The New Orleans Invitational Billfish Tournament and Cajun Canyons Billfish Classic give you the opportunity to connect with other anglers, share experiences, and celebrate the rich fishing culture of Louisiana. 

Louisiana Deep Sea Fishing Rules and Regulations

Before we wrap up, let’s go over some essential rules and regulations to ensure your fishing trip is smooth and legal. First off, anglers aged 16 and older need a valid fishing license when fishing in Louisiana’s waters. If you’re fishing with a registered charter, this is usually covered, but you’ll need to get your own if you’re heading out alone. 

You’ll also need an Offshore Landing Permit to target species such as Billfish, Tuna, and Amberjack. Always check with your captain, as these permits are often included in the price of the charter.

Certain fish species have seasonal closures to protect them during spawning, so it’s crucial to check these seasons before planning your trip. Additionally, there are strict bag and size limits for almost every species. For instance, most Billfish must be released and, if you catch Sharks or Bluefin Tuna, make sure to report it to the NMFS. You can find all the details of the latest regulations from the Louisiana Department of Wildlife and Fisheries
