About Mahi Mahi Fishing in Portsmouth
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 Portsmouth
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 Portsmouth
Top spots where local captains target mahi mahi and other deep sea fishing species.
Guadeloupe Channel
The deep channel between Dominica and Guadeloupe funnels Caribbean currents through a productive passage where blue marlin, wahoo, and yellowfin tuna concentrate along current edges. The channel is the primary offshore fishing ground for Portsmouth-based charters.
North Coast Drop-Off
Dominica's north coast shelf drops sharply into deep Caribbean water where blue marlin, wahoo, and large mahi-mahi patrol the depth transition. The drop-off is remarkably close to shore, making it possible to reach bluewater fishing grounds within minutes of leaving Portsmouth.
Northwest FADs
Fish Aggregating Devices deployed northwest of Dominica in deep Caribbean water attract mahi-mahi, wahoo, and blackfin tuna. The FADs provide reliable offshore action for Portsmouth charter boats during the spring and summer pelagic season.
Les Saintes Channel
The channel between Dominica and Les Saintes (Guadeloupe) features strong currents and deep water that concentrate wahoo, yellowfin tuna, and sailfish along temperature breaks. The channel's productivity is driven by nutrient upwelling from the deep volcanic basin between the islands.
