Note: Sailfish and other billfish are generally released, and many rules require circle hooks. Size limits, bag limits, and seasons for this species change often, so check current state and federal rules before you keep one.

How to identify it

  • A very tall, sail-like dorsal fin spotted with dark dots.
  • A long, pointed bill.
  • A slim blue body with pale vertical bars.
  • A forked tail.

Baits and lures

  • Live baits such as goggle-eyes and blue runners
  • Dead baits and lures
  • Flies

Techniques

  • Fish live baits from a kite or a slow-trolled spread.
  • Use circle hooks to improve survival.
  • Fight fish quickly and release them in the water.
  • Cast to fish seen crashing bait at the surface.

Field notes

A sailfish raises its sail to herd baitfish. Anglers use light tackle and often handle the fish only briefly.

Some species are catch-and-release only or closed in certain areas.
