Bluefin
Tuna.

Thunnus thynnus

The fish that built Montauk's offshore reputation. Atlantic bluefin push through East End waters from late spring into early winter — school fish around the Point, giants in the canyon walls. One bite from a 600-pounder can fund the rest of your season.

01The Fish

The largest tuna and one of the fastest fish in the ocean. Streamlined, deep-bodied, with retractable fins built for high-speed pursuit and the unique ability among bony fish to maintain a body temperature warmer than the surrounding water. Bluefin are warm-blooded predators that range from the Mediterranean to the Gulf of Mexico to Newfoundland — and they pass right through the East End on the way.

Classified into School (under ~73"), Large School (~73-81"), Small Medium (~81-119"), and Giant (119"+ / 310+ lb). Each class has different federal regulations. Most East End anglers tangle with school fish — true giants are the trophy hunt that defines a career.

02When & Where

Late June through July. First school fish arrive on the south side and out around the Point. The Butterfish hole, the dump, and the 30-fathom line all hold fish in early summer. Look for slicks, bird piles, and the bait.

August through September. Peak. School fish stack up around Montauk, and giant tuna start working the canyon walls — Hudson, Block, Atlantis, and Veatch all produce. This is also when the inshore push of school fish happens in some years, sometimes within sight of land.

October into November. The big fish are still out there but harder to find. Cold pushes scatter the schools; the boats that catch fish in November are the ones willing to push offshore and stay late. The window closes by Thanksgiving.

03How to Catch Them

Bluefin tuna fishing breaks into three main approaches, often combined in the same day.

Live-line. The premium method for trophy fish. Slow-troll a live mackerel, herring, or bunker on a heavy circle hook behind the boat. When a bluefin commits, hold on. This is what produces the giants.

Chunking. Anchor on structure, set a slick of cut butterfish or bunker, drift hooked baits through it. Patient game. Produces a lot of school fish and the occasional giant.

Trolling and jigging. Spreader bars, daisy chains, and big swimbaits trolled at 5-7 knots cover water. Vertical jigging with heavy metals (RonZ, butterfly jigs) is deadly when fish are marked deep.

Live Baits That Work

  • Mackerel (Atlantic)
  • Bunker (live)
  • Herring
  • Squid (offshore)
  • Sand eels (jig & drop)

Lures & Tackle

  • Heavy spreader bars + daisy chains
  • Bombers (deep diving)
  • RonZ vertical jigs (200g+)
  • Heavy stand-up gear (80W-130W)
  • Circle hooks 10/0 – 16/0

04Regulations · NY 2026

Current regulations as of the May 12, 2026 NYSDEC update. Always verify before keeping fish — regs change.

Federal vs State

Bluefin tuna doesn't appear in the NY DEC marine regulations table because it's regulated entirely by NMFS. The state still requires the Marine Registry, but bag/size limits, season, and reporting all come from federal rules — and those rules change inside a season as quotas fill.
