Also known as
- Bluefin Tuna US
- Northern Bluefin Tuna US
- Giant Bluefin US
Identification
A colossal Atlantic apex tuna — a thick-shouldered torpedo built for cross-ocean migration and brutal multi-hour fights. Males and females reach similar sizes.
- Deep metallic blue to nearly black on top, bright silver-white belly
- Yellow finlets edged with black
- First dorsal yellowish; second dorsal and anal fins dusky to yellow
- Very short pectoral fins relative to massive body size
- Small eyes relative to the enormous head
Where it holds
- Offshore
- Oceanic
Behaviour
An Atlantic basin apex predator with extraordinary endothermic capability — sustains hunting in cold temperate water that excludes most pelagics. Migrates between subtropical breeding grounds and North Atlantic feeding grounds. Hunts throughout the water column 0-1000m with explosive coordinated school attacks on bait. Strong site fidelity to feeding zones drives predictable seasonal aggregations along thermal fronts and upwelling edges.
Diet: Herring, Mackerel, Menhaden, Sand Lance, Small Bonito, Squid
How it's caught
Line Fishing
Chunking
The defining New England, Maritimes, and offshore Mid-Atlantic approach. Anchor or drift along productive ground (Stellwagen, Cape Cod, the Mud Hole, Hudson Canyon) and establish a steady chum slick of cut herring, mackerel, butterfish, or pogies. Free-line unweighted chunks on 10/0-12/0 non-offset circle hooks back through the slick. 37-60kg gear with long fluorocarbon leaders.
Live Lining
A trophy-class approach when bait schools concentrate fish. Slow-troll or drift a live mackerel, herring, menhaden, or butterfish on a 10/0-12/0 non-offset circle hook with downrigger or sliding-sinker rig. Bridle the bait. Kite fishing keeps baits on the surface in clear conditions. Heavy 60-80kg gear for giants. Norwegian and Canadian charter standards.
Trolling
A high-mileage approach for finding fish across temperature breaks and bait concentrations. Pull a spread of x-large skirted lures, daisy-chained green machines, plungers, jet heads, and rigged ballyhoo at 6-10 knots. Spreader bars and squid chains raise schooling fish. 37-60kg gear with non-offset circle hooks. Wide outrigger spread mandatory.
Spinning
An exhilarating sight-cast approach to bust-ups, breezers, and birds working bait under the surface. Pitch 250-400g large stickbaits, poppers, or weighted soft plastics into the school. Aggressive walk-the-dog or fast-pop retrieves trigger explosive strikes. PE6-10 popping setups with 100-150lb fluoro leader. Cape Cod and Mid-Atlantic mainstay.
Jigging
Effective when fish hold deep at 50-200m on banks, rips, and structure. Drop a 300-600g knife jig or slow-pitch jig and rip with sharp 1-2m cadence sweeps; many strikes come on the flutter fall. PE6-10 braid with 6-7m of fluorocarbon topshot. Demanding work — fitness required.
Spear Fishing
Bluewater Spearfishing
An elite Atlantic and Mediterranean bluewater target with deep heritage in the Med. Surface-feeding fish in 10-40m during seasonal migrations provide the encounter window. Curious circlers — flasher and chum bag help draw them in. Use a 140-160cm bluewater speargun with 9.0-10.0mm shaft, slip-tip, breakaway rig, and 100L+ float system. Brain or spine shots only.
