Patience, precision, and putting yourself in the right water. By Captain Ricky Wheeler
If you're serious about bigeye tuna fishing in the Mid-Atlantic canyons, you already know this isn’t a numbers game. It’s a precision game. Bigeye tuna are deep-dwelling, structure-oriented predators that demand patience, timing, and the right offshore trolling strategy. From targeting canyon notches in 100–400 fathoms to dialing in your trolling spread for low-light feeding windows, catching bigeye tuna in the Northeast requires a different mindset than yellowfin fishing. In this guide, I’m breaking down the exact approach I've used aboard the multiple boats I have run to consistently and effectively target bigeye tuna in the Mid-Atlantic and Northeastern canyons.
If you’ve ever wanted to hear a big game reel dumping line at grey light with a true canyon giant on the other end this one’s for you...
There are very few moments in offshore fishing that compare to the chaos of a bigeye tuna bite.
It starts with a sudden eruption, massive explosions detonating in your trolling spread. Whitewater turns to screaming drags in seconds, and if you’re lucky, your reel has a loud clicker because that sound, a bigeye absolutely dumping line, is one of the best in fishing. These aren’t just tuna. These are bruisers. And if you’re undergunned, they’ll let you know immediately.
Bigeye tuna fishing in the Mid-Atlantic and Northeastern canyons is equal parts skill, patience, and timing. They can be abundant one day and completely absent the next. When it all comes together, though, few fisheries on the East Coast can match it.
Understanding the Bigeye Tuna
Bigeye tuna are built different — and they behave differently than most of the tunas we chase offshore.
These fish can exceed 400 pounds, with the current Atlantic all-tackle IGFA record standing at 392 pounds, 6 ounces (Spain, 1996). In our region, most bigeyes fall in the 120–200 lb class, but every season produces a handful of true giants pushing to weights of over 300 pounds.
What makes bigeyes especially elusive is where they live.
Unlike yellowfin tuna — which spend roughly 70% of their time above 200 feet — bigeyes are a deep-water species. They commonly hold below 200 feet and have been recorded diving to depths exceeding 1,800 feet. This deep, vertical behavior is why bigeyes often surprise daytime sword fishermen and why many of the best bigeye trolling bites happen in the same areas that produce swordfish.
Bigeye Identification (And Why It Matters)
Correct identification is critical — especially when distinguishing bigeye tuna from bluefin tuna, which can lead to illegal harvests depending on the season.
Key Bigeye Characteristics:
Round, thick body — noticeably fatter than yellowfin or bluefin
Large eye (especially noticeable side-by-side)
Yellow dorsal fin, with lighter yellow second dorsal and anal fins
Bright yellow finlets with black edges
Bigeye vs. Yellowfin:
Bigeyes have shorter sickle fins (second dorsal and anal)
Yellowfin appear longer and more exaggerated in those fins
Bigeye vs. Bluefin:
Bigeyes have more yellow coloration in the second dorsal fin
Bluefin second dorsal fins are noticeably darker
Bigeyes have longer pectoral fins, extending to the start of the second dorsal
Bluefin pectorals are much shorter
Bigeyes have a rounder head and thicker body
When in doubt, slow down and confirm — especially in mixed tuna fisheries.
Targeting Bigeye Tuna: The Mindset
If there’s one word that defines successful bigeye fishing, it’s patience.
Bigeyes don’t live in your trolling spread the way yellowfins do. They move vertically, spending most of their time deep and only coming up to feed during specific windows. Your job is to be in the right place, over the right structure, at the right time — and wait them out. It can be very grueling and truly tests your grit.
Structure & Depth: Where Bigeyes Live
While bigeyes are occasionally caught shallower, the odds increase dramatically once you commit to deeper water.
Prime bigeye zones:
100–400 fathoms (most consistent)
Canyon notches and corners
Seamounts and hard structure
Smaller canyons along the natural 100-fathom line
Certain “bigeye notches” have earned their reputation for a reason — but they’re not the only places holding fish. Any piece of defined structure in the right depth range can produce.
Water: Finding the Right Conditions
Satellite data is a major advantage when targeting bigeyes. Satellite imagery reports like Roffs truly help you dial these water characteristics in whether you are a seasoned pro or just starting out.
Early in the season (May–June), success revolves around warm, blue Gulf Stream eddies breaking off and pushing into the continental shelf. The western edges of these eddies — where blue water meets green — are prime feeding zones.
Bigeyes (like most apex predators) use:
Temperature breaks
Color changes
Chlorophyll edges
As summer progresses and water warms, those breaks become less defined, making timing and structure even more important.
Timing the Bite
Bigeyes are creatures of low light.
Peak bite windows:
Just before and after first light
Just before and after last light
Occasionally pre-dawn and post-sunset dark trolling
When I know bigeyes are around, I make sure the boat is positioned on sharp structure in the 100–300 fathom zone before first light. Once the sun gets up, I’ll often shift to yellowfin grounds — then slide right back out late in the day for another shot.
If I were strictly targeting bigeyes? I’d stay in 100–400 fathoms all day. Daytime bites absolutely happen, especially around structure.
Watch the Whales
Pilot whales are one of the strongest visual indicators of bigeye presence in the canyons.
When pilot whales are holding on known bigeye structure, pay attention. If you’re marking bait and the whales become active, drill that area. More often than not, it’s feeding time — and bigeyes are usually part of the equation.
Building a Bigeye Trolling Spread
Bigeyes primarily feed on forage in the 9–12 inch range, and your spread should reflect that.
Proven Bigeye Producers:
Large skirted ballyhoo
Sea Witch–style lures (3–5 oz) over:
Wolfpack Ahi tails
Ron Zs
This combination has been a staple in my spreads worldwide for over a decade.
Spreader bars have their place — particularly larger bars — but most of my bigeyes have come on single baits, not bars.
Diving Plugs:
Bomber CD30
Rapalas
Nomad DTX Minnow
Run them on flat lines with braided line, typically ~100 feet back, and upgrade all hooks and split rings where needed. Bigeyes will find the weak link every time.
Trolling speed:6–7.5 knots, adjusted for conditions and bait performance.
The Fight: Where Battles Are Won or Lost
A bigeye fight feels like pulling against a tractor.
The most important decision you’ll make once hooked up? Harness choice and setup.
From the first minute of the fight, you should be locked into:
A large plate belt
A lower back / butt harness
No shoulder harnesses
The goal is to fight the fish with your core and body weight, not your arms or back. Shoulder harnesses fatigue anglers fast and take away leverage.
The End Game
Bigeyes are tough — and landing them requires preparation.
While we fish IGFA-compliant on EUPHORIA and other boats I run, there are scenarios where a harpoon can be useful (non-IGFA situations), especially if:
The angler is exhausted
The fish is hooked on lighter tackle
Otherwise:
Always have a second gaff ready
Expect 2–3 people to pull a bigeye over the rail
Take the shot that’s there — not the perfect one

Final Thoughts
Nothing replaces time on the water. But understanding how bigeye tuna behave — where they live, when they feed, and what they respond to — dramatically increases your odds.
If this insight helps put you in position when a bigeye wolfpack finally erupts in your spread, then it’s done its job.
See you in the canyons.
