About Yellowfin Tuna Fishing in Portsmouth
A powerful open-water predator prized for sashimi-grade flesh. Found in blue water near rips and structure.
Yellowfin Tuna are among the most powerful and prized offshore gamefish in the world. Their torpedo-shaped body is designed for sustained high-speed swimming, with a dark metallic blue back, silver-gold sides, and bright yellow finlets and fins that give them their name. Mature yellowfin develop extraordinarily long second dorsal and anal fins that sweep back like sickles. These warm-blooded fish (one of few fish that can maintain elevated body temperature) are found in deep blue water near oil rigs, floating debris, and temperature breaks. Their sashimi-grade flesh is among the finest seafood in the world.
Scientific name: Thunnus albacares

How to Catch Yellowfin Tuna in Portsmouth
Techniques & Bait
Chunking (cutting fresh baitfish into chunks and creating a chum slick) with yellowfin tuna hooks baited with fresh chunk bait is deadly when fish are located near structure or rigs. Live bait (hardtails, blue runners, goggle-eyes) drifted on the surface or at depth with a balloon or kite produces the largest fish. Trolling with cedar plugs, skirted ballyhoo, and spreader bars at 6-8 knots covers water when fish are scattered. Jigging with heavy butterfly jigs under the boat when fish are marked on the sounder is increasingly popular.
Recommended Tackle
Heavy conventional rod, 50-80 lb class reel, 65-100 lb braid, 80-130 lb fluorocarbon leader (at least 15 feet), 7/0-9/0 circle hooks. For chunking: medium-heavy spinning with 40-65 lb braid. Stand-up gear for fish over 100 lbs.
Best Deep Sea Fishing Fishing Spots in Portsmouth
Top spots where local captains target yellowfin tuna 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.
