Sailfish

The Atlantic sailfish is Brazil's marquee offshore billfish. Along the country's 4,500-mile coastline — particularly off the Northeast — sailfish draw sport anglers and support both artisanal and industrial fisheries.
They're the most heavily targeted billfish species in Brazilian waters, pursued almost entirely as a catch-and-release gamefish by sport boats trolling the blue water beyond the continental shelf.
Scientific Name: Istiophorus albicans
Also known as Agulhão-vela, vela
- Unmistakable oversized dorsal fin — the "sail" — runs nearly the full length of the back and stands taller than the fish's body depth when raised.
- Deep cobalt-blue back fading to silver-white on the belly; faint vertical bars of pale blue or lavender dots along the flanks.
- Long, slender bill (upper jaw extended into a spear) distinguishes it from marlin, which are far more heavily built.
- Typical sport-caught fish run 6–8 feet; larger individuals can reach 10 feet and exceed 200 lbs, though most Brazilian fish are well under that.
What to know
Habitat Distribution
- Native to the Atlantic Ocean; found throughout Brazilian offshore waters from the Amazon mouth south along the entire coastline.
- Most heavily concentrated off Northeastern Brazil, where industrial, artisanal, and sport fisheries all intersect on the same population.
- Pelagic and wide-ranging — lives in the open ocean but moves inshore into shallower water during warm-season spawning periods.
- Prefers warm, blue offshore water; generally found beyond the continental shelf edge where currents concentrate baitfish.
Key Locations
- Northeastern Brazil coastline — the most documented concentration of sailfish in Brazilian waters, targeted by all three fishing sectors.
- Offshore Atlantic waters along the full Brazilian coast, accessible from major port cities with charter fleets.
Specific Spots
- Current edges and temperature breaks in blue water offshore — sailfish stack where warm current meets cooler upwellings that push baitfish to the surface.
- During spawning season, fish move into shallower inshore water and can sometimes be spotted with their sails breaking the surface.
- Floating debris, weed lines, and any structure in open water concentrate the small tunas, squid, and ballyhoo that sailfish chase.
Sailfish FAQ
Answers from onWater's species guide.
What are the best lures and bait for Sailfish?
Rigged natural ballyhoo, whole or half, is the go-to trolling bait, either naked or skirted with a soft plastic trolling skirt in blue/white or pink/white to add action and visibility.
When is the best time to fish for Sailfish?
Warm-season months (roughly October through March in the Southern Hemisphere) generally produce the best sailfish action as water temperatures peak and fish move inshore to spawn.
How do you catch Sailfish?
Sport anglers in Brazil target sailfish almost exclusively from offshore charter boats, trolling a spread of rigged ballyhoo or skirted lures across blue water beyond the shelf edge. Catch-and-release is the norm in the sport fishery; crews use release gloves to handle the fish at boatside without bringing it aboard.
What do Sailfish eat?
Primarily small pelagic fish, ballyhoo, sardines, small tunas, and mackerel, plus squid. This is why trolled rigged ballyhoo or artificial lures that mimic slender baitfish are the standard approach.
Where do Sailfish live?
Native to the Atlantic Ocean; found throughout Brazilian offshore waters from the Amazon mouth south along the entire coastline. Most heavily concentrated off Northeastern Brazil, where industrial, artisanal, and sport fisheries all intersect on the same population.
