Saltwater · Winter peak off South Florida, December to March; summer in the northern Gulf
Sailfish
Istiophorus platypterus
Florida's official saltwater fish, an offshore billfish with a huge sail-like dorsal fin that is unmistakable. Off South Florida and the Keys it is the classic winter light-tackle target. Catch-and-release is the norm — fish are kept in the water, revived and released, with no harvest promotion.
Seasons · Peak
Identifying features
- Huge sail-like first dorsal fin, taller than the body depth, deep blue with dark spots
- Long bill, slender dark-blue back, silver belly and vertical bars when lit up
- Sail folds down into a groove when the fish swims fast
- Much smaller and slimmer than a blue marlin, with a far taller sail
- Commonly 5-7 ft (1.5-2.1 m) long including the bill
Habits
- Hunts sardines, threadfins and other baitfish near the surface, herding them with its raised sail
- Raises the sail and lights up with bars when feeding or hooked
- Often travels in small groups off South Florida in winter, following bait along reef edges
- Among the fastest fish in the ocean in short bursts
- Almost always released: keep it in the water, remove the hook if safe, and revive it boatside
Distribution
Where to find them
- Off Miami, Fort Lauderdale and Palm Beach along the reef edge in winter
- Florida Keys offshore colour changes and rips
- Northern Gulf weed lines and rips in summer
Where they live
How to catch them
Kite fishing with live baits off South Florida Boat
Rig: Boat fishing with fishing kites suspending live goggle-eyes or threadfins at the surface on 20-30 lb tackle, circle hooks and long leaders
Bait/lure: Live goggle-eyes, threadfin herring
Key tip: Keep baits at the surface along reef edges and colour changes; release the sailfish in the water and revive it before letting go.
Trolling ballyhoo and strip baits Boat
Rig: Trolling rigged ballyhoo and strip baits with teasers along reef edges and colour changes at 5-8 knots
Bait/lure: Ballyhoo, strip baits
Key tip: Watch teasers for a lit-up sailfish, drop back a bait, and use circle hooks for a clean corner-of-jaw hook-up and release.
