About Mahi Mahi Fishing in Islamorada
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 Islamorada
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 Islamorada
Top spots where local captains target mahi mahi and other deep sea fishing species.
Islamorada Hump
The Islamorada Hump is a deepwater seamount formation roughly 15-20 miles south of Islamorada where the bottom rises from over 600 feet to around 400 feet. This structure concentrates blackfin tuna, wahoo, mahi-mahi, and swordfish in significant numbers. Deep-dropping for swordfish on the Hump has become a signature Islamorada offshore technique.
Gulf Stream Edge (Islamorada)
The Gulf Stream runs approximately 8-12 miles off Islamorada's reef line, bringing warm bluewater current and pelagic species within easy range. Sailfish, mahi-mahi, wahoo, and blackfin tuna patrol the Stream edges, especially along weed lines and temperature breaks. Islamorada's proximity to the Stream makes it one of the top bluewater destinations in the Keys.
409 Hump
The 409 Hump is a deepwater bottom formation south of Islamorada named for the GPS coordinates, where the ocean floor rises to create a fish-concentrating feature. Blackfin tuna, wahoo, mahi-mahi, and swordfish gather around this structure in deep water. It is a key waypoint for Islamorada offshore captains targeting pelagic species and deep-drop swordfish.
Tennessee Reef (Deep Edge)
The deep outer edge of Tennessee Reef drops from 60 feet to hundreds of feet along the reef wall southeast of Islamorada. Mutton snapper, black grouper, yellowtail snapper, and cubera snapper hold on the deep reef ledges. Sailfish and kingfish troll along the reef edge, making it productive for both bottom fishing and trolling.
