Giant bluefin crash the 100-fathom line as bunker feeds fire the canyon

The Hudson Canyon has exploded this week with some of the best bluefin action I've seen in years. We're talking legitimate giants — fish pushing 96 inches — stacked along the 100-fathom line where the thermocline has set up a perfect feeding zone.

The bite started wide open with bunker feeds that looked like whitewater from a distance. These weren't the deep sand eel presentations we expected for late June — the tuna were up top, absolutely demolishing bait pods in spectacular fashion. When they're feeding like this, presentation is everything. The UVT stick baits have been absolutely deadly, especially when the fish are aggressive on top. Cast into the mayhem and hang on.

But here's where it gets interesting — when the surface action dies, these fish don't disappear. They're dropping down and holding tight to structure, sometimes just 5 feet off the bottom in 75 to 80 feet of water. That's where the jigs shine. I've been running 280-gram metals with beefed-up hooks, bouncing them slow through the water column on the drift. First drift of the day last week, we were tight on another jumbo within 15 minutes.

The key is reading the tide. These fish are responding to the current switches — when that tide flips, they reposition along the thermocline. I'm running about 35 pounds of drag to start, but these fish will test every ounce of it. The pressure game is critical when you're dealing with tuna this size in structure.

What's driving this bite is textbook canyon dynamics. The thermocline has locked in around 45 to 50 feet, creating a temperature break that's concentrating bait. Bunker are getting pushed up against this thermal wall, and the tuna are positioned perfectly to ambush them. The recent weather pattern — high pressure, light northwest winds, and bright sun — has stabilized the water column and made the fish predictable.

Mahi are also showing in decent numbers along the weed lines, responding well to feather rigs and traditional trolling presentations. The grass lines have been holding fish consistently, and when you find a school, the action can be fast and furious. Ten-foot 80-pound leaders to a long-shank Mustad hook have been the go-to setup for the bailing rod action.

The canyon edge from the Claw down to the Dip has been the most consistent zone, with fish scattered along the entire 100-fathom contour. Water temps are holding steady in the mid-60s on the surface with that crucial thermal break below. The current has been moderate but consistent, perfect for both trolling and jigging presentations.

Looking ahead, this pattern should hold through the weekend. The moon phase is working in our favor — we're approaching new moon, which typically means more stable conditions and better daytime fishing. With continued light winds forecast, expect the thermocline to remain locked in place, keeping bait concentrated and tuna feeding aggressively.

The key is versatility. Come prepared for both surface action and deep presentations. When you see the birds and the whitewater, have those stick baits ready. When it goes quiet, don't leave — drop the jigs and work the water column. These fish are here in numbers, and they're feeding. It's just a matter of matching your presentation to their mood.
