About Mahi Mahi Fishing in Roseau
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 Roseau
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 Roseau
Top spots where local captains target mahi mahi and other deep sea fishing species.
Dominica Channel South
The deep channel south of Dominica between the island and Martinique holds blue marlin, wahoo, yellowfin tuna, and sperm whales in nutrient-rich volcanic waters. The channel's depth and current dynamics create exceptional offshore fishing conditions within a short run from Roseau.
West Coast Drop-Off
Dominica's leeward shelf drops rapidly into deep Caribbean water, with the 1,000-foot depth contour lying remarkably close to shore. Blue marlin, wahoo, and yellowfin tuna patrol this dramatic depth transition, making Dominica one of the few islands where billfish can be reached in under 20 minutes.
Caribbean FADs
Fish Aggregating Devices deployed west of Dominica attract mahi-mahi, wahoo, and blackfin tuna to floating structure. Dominica's FAD program supports both commercial and recreational fishing, providing reliable offshore action from Roseau.
Soufrière Volcanic Deep
The deep water off Soufrière Bay features underwater volcanic vents that create nutrient upwelling, attracting an extraordinary food chain from plankton to blue marlin. The volcanic activity creates unique offshore fishing conditions where gamefish concentrate around thermal plumes.
