About Yellowfin Tuna Fishing in Islamorada
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 Islamorada
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 Islamorada
Top spots where local captains target yellowfin tuna 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.
