White marlin are the billfish of the Northeast canyons. In the right late-summer conditions, boats trolling the edge will raise them into the spread, and an angler who has never seen a billfish light up and slash at a bait is in for something they will remember for the rest of their life. This is a catch-and-release fishery built on careful handling.
How to identify them
White marlin are the smallest of the Atlantic marlins, slim and elegant, with a rounded tip to the first dorsal fin and rounded pectoral fin tips (blue marlin's are pointed), and often a lit-up lavender-and-silver color when feeding. The bill and the sail-like dorsal are classic billfish. Compare with the larger, heavier-shouldered blue marlin.
Where and when
Whites ride the warm water up to the canyon edges and temperature breaks in late summer into early fall. Like all our offshore fishing, it comes down to finding the right water, the warm blue push, the break, the bait, along the edge.
Tip Billfish frequently come up on a teaser or a hooked bait and slash before they eat. Watch the spread, drop back to a marlin that lights up, and give it a moment to turn on the bait before you come tight.
How to catch them
White marlin are taken on trolled rigged baits, small skirted lures, dredges and teasers, often on lighter tackle that makes the fight sporting. Many crews fish circle hooks with natural baits specifically to improve release survival.
Handling and conservation
Billfish survival depends on the release. Use circle hooks, keep the fish in the water, minimize the fight and handling time, support and revive the fish, and let it swim off strong. A released white marlin is worth far more than a dead one.
