About Mahi Mahi Fishing in Dauphin Island
Also called Dolphin or Dorado. Stunningly beautiful and acrobatic. Excellent eating.
Mahi Mahi — also called Dolphin or Dorado — are the most brilliantly colored fish in the ocean. Their iridescent body shimmers with electric blues, greens, and golds that literally change before your eyes. Males (called "bulls") develop a prominent flat forehead, while females ("cows") have a more rounded head profile. These fast-growing pelagic fish are found in blue water near floating debris, weed lines, and current edges. They are acrobatic fighters that tailwalk across the surface and make spectacular aerial leaps.
Scientific name: Coryphaena hippurus

How to Catch Mahi Mahi in Dauphin Island
Techniques & Bait
Trolling ballyhoo rigged with colorful duster/lure combinations along weed lines, current edges, and near floating debris is the classic technique. Once a school is located, stop the boat and pitch live pilchards, cut ballyhoo, or small live baits to the school — mahi travel in groups and multiple hookups are common. Casting light jigs, spoons, or fly-rod streamers to fish visible near floating objects is incredibly exciting. Keep one fish in the water next to the boat to hold the school in place while catching others.
Recommended Tackle
Medium spinning or conventional rod (6'6"-7 ft), 4000-5000 reel, 20-30 lb braid, 30-40 lb fluorocarbon leader. For trolling: 20-30 lb class conventional rigs. Mahi have sandpaper-like mouths — fluorocarbon leader works fine (no wire needed).
Best Deep Sea Fishing Fishing Spots in Dauphin Island
Top spots where local captains target mahi mahi and other deep sea fishing species.
Alabama Offshore Artificial Reefs
Alabama's world-class artificial reef system includes thousands of deployed structures in 80-200 feet of water south of Dauphin Island. Red snapper, gag grouper, scamp grouper, triggerfish, and amberjack hold on the reefs in extraordinary numbers. The density of artificial reef material offshore of Alabama is unmatched anywhere in the Gulf of Mexico.
The Liberty Ships
Several World War II-era Liberty Ships have been sunk as artificial reefs approximately 15-25 miles south of Dauphin Island in 60-100 feet of water. These massive steel hulls have become thriving marine ecosystems holding red snapper, amberjack, grouper, and schools of baitfish. The Liberty Ships are among the most iconic artificial reef destinations in the Alabama fleet.
DeSoto Canyon (from Dauphin Island)
DeSoto Canyon is accessible on long-range trips from Dauphin Island, with the canyon edge approximately 60-80 miles to the south. Yellowfin tuna, blue marlin, wahoo, and swordfish patrol the dramatic depth transitions along the canyon walls. The canyon's nutrient-rich upwelling creates a food chain that supports world-class bluewater fishing.
Mobile County Offshore Ledges
Natural limestone ledge formations south of Dauphin Island in 100-150 feet of water provide excellent bottom-fishing habitat alongside the artificial reef structures. Red snapper, gag grouper, amberjack, and vermilion snapper hold along the ledge faces and overhangs. These natural features combined with Alabama's artificial reefs create some of the most productive bottom fishing in the Gulf.
