Best Deep Sea Fishing Fishing Spots in Port Fourchon
Top spots where local captains target blackfin tuna and other deep sea fishing species.
Grand Isle Block Platforms
The Grand Isle oil and gas blocks begin just a few miles offshore of Port Fourchon, creating one of the densest concentrations of offshore platform structure in the Gulf of Mexico. Red snapper, amberjack, cobia, king mackerel, and ling hold on the rig legs in enormous numbers, with some platforms accessible in less than an hour from the dock. Port Fourchon's position as the southernmost port in Louisiana provides an unmatched advantage in reaching productive offshore structure quickly.
The Midnight Lump
Midnight Lump rises from the Gulf floor approximately 70 miles south of Port Fourchon, where its salt dome structure creates upwelling currents that concentrate yellowfin tuna, blue marlin, and wahoo. The lump is one of the Gulf's most reliable bluewater destinations, producing trophy yellowfin tuna and white marlin throughout the fishing season. Port Fourchon's proximity to deep water makes it the premier launch point for targeting Midnight Lump and surrounding bluewater features.
Deepwater Horizon Area
The deepwater oil production area south of Port Fourchon features towering production platforms and floating rigs in water depths exceeding 1,000 feet, attracting massive concentrations of pelagic species. Yellowfin tuna, blue marlin, wahoo, and swordfish patrol the current edges and temperature breaks around these deepwater structures. Port Fourchon is the closest mainland port to these deepwater fishing grounds, giving anglers the shortest possible run to world-class bluewater action.
South Pass (Mississippi River Delta)
South Pass at the southeastern tip of the Mississippi River delta discharges nutrient-laden river water into the Gulf, creating a collision zone that attracts yellowfin tuna, cobia, jack crevalle, and tarpon. The muddy river plume meets the clear Gulf water along visible color changes and current rips that concentrate baitfish and predators. Charter boats from Port Fourchon run east to fish the delta passes for a unique offshore experience blending river and Gulf fishing.
