How to Catch Blue Marlin in the Southeast Atlantic
The short answer
Blue Marlin in the Southeast Atlantic hold on bluewater. They peak May–Aug. Start with high-speed trolling lure: Big skirted lures 7–9 kt in a spread over the ledges — the classic way to raise a blue. All day on the troll; the raise often comes in the heat of the afternoon.

What to throw for Blue Marlin
Best first. The retrieve matters more than the lure, so each one says how to work it.
- High-speed trolling lure — Big skirted lures 7–9 kt in a spread over the ledges — the classic way to raise a blue.
- Ballyhoo (trolled) — Horse ballyhoo behind an Ilander-style skirt for a natural option in the spread.
- Live bait — A bridled small tuna slow-trolled when you've marked a fish — the big-bite bait.
Where to find them
Look for bluewater.
Find the bait first — a temperature break with flyers and birds beats empty pretty water. Blues are effectively all-release: keep the fish in the water boat-side and get the hook or cut close.
Tide and timing
Tide isn't the driver for blue marlin — all day on the troll; the raise often comes in the heat of the afternoon.

Check the regulations
Size and bag limits change by state and by season, and they change more often than any article gets updated. Check your state agency before you keep anything.
