Albacore
Albacore — called albacora or atún blanco locally — are a genuine offshore target along Chile's central and southern Pacific coast.
Schools feeding on sardines draw both spin and fly anglers from ports like Valparaíso and from lodge-based boats in the Los Lagos region.
March and April are the prime months, when fish in the 7–10 kg range push baitfish to the surface and give anglers a shot at fast, sustained action.
Scientific Name: Thunnus alalunga
Also known as Albacora, atún blanco, longfin tuna
- Torpedo-shaped body, metallic dark blue on the back fading to silvery white on the belly — clean, streamlined profile built for speed.
- The giveaway ID feature: pectoral fins that extend well past the second dorsal fin, noticeably longer than on any other tuna you'll encounter offshore.
- White trailing edge on the tail fin; no bright yellow finlets like yellowfin tuna.
- Most fish encountered in Chilean waters run 7–10 kg; larger adults can push past 30 kg, though those are less common inshore.
What to know
Habitat Distribution
- A wide-ranging pelagic species found in temperate and tropical Pacific waters — present along Chile's coast as part of the South Pacific stock.
- Concentrates in the epipelagic zone (near-surface to mid-water column) in clean, blue offshore water, particularly where cooler upwelling water meets warmer surface currents.
- Fishing areas have been documented off Chile's central zone; offshore grounds near Valparaíso, Iquique, and Antofagasta are known departure points.
- Schools associate with temperature breaks, submarine features like seamounts and canyons, and surface bait activity — especially sardine schools.
Key Locations
- Central Chilean coast near Valparaíso — a documented offshore fishing port with access to productive temperature-break grounds.
- Northern ports of Iquique and Antofagasta — departure points for offshore pelagic fishing in warmer northern waters.
- Los Lagos region (southern Chile) — lodge-based boats, including those on the Río Petrohué coast, report productive tuna fishing in March and April when sardine schools concentrate offshore.
Specific Spots
- Temperature breaks where cooler upwelling water meets warmer blue water — these edges concentrate bait and hold fish near the surface.
- Wherever birds are working over the water: albacore push sardines to the surface, and diving birds mark the spot from a distance.
- Around seamounts and offshore canyon edges, where depth changes trigger upwelling and bait aggregations.
- Floating debris and sargassum patches can hold schools, especially when clean blue water surrounds them.
Albacore FAQ
Answers from onWater's species guide.
What are the best lures and bait for Albacore?
Casting jigs in chrome, white, or blue-and-white, 40–80g, are the go-to when fish are crashing bait on the surface; match the size to the sardines being chased. Squid-pattern soft plastics and hard lures in pink or white produce well given albacore's preference for cephalopods; rig them on a fast-retrieve setup.
What flies work for Albacore?
Baitfish streamers, Clouser Minnows (which imitate small fish) and Deceivers in white, chartreuse, or blue-over-white, sized to match local sardines, are the standard surface-blitz fly.
When is the best time to fish for Albacore?
March and April are the peak months for surface-feeding albacore along Chile's central and southern Pacific coast. January and February can produce fish, particularly when trolling offshore, though schools are less reliably on top during midsummer.
How do you catch Albacore?
Most albacore fishing in Chile happens from charter or lodge boats running offshore to find temperature breaks and bird activity. Trolling covers water to locate schools; once surface feeding starts, switching to casting jigs or flies into the blitz produces the fastest action.
What do Albacore eat?
Squid are the primary forage, more so than for most other tuna, which makes squid-imitating lures and flies a reliable first choice. White or pink squid-pattern jigs and soft plastics work well.
