Pacú Fishing - Lodges, Destinations & Guided Trips

Fishing for Pacú

Pacú are strong, wary, and visually distinct freshwater gamefish found in warm jungle rivers. Known for their crushing jaws and surface takes, they’re an exciting fly or spin target in parts of northern Argentina.

Pacú are part of the serrasalmid family—relatives of piranha, but with a more varied and mostly vegetarian diet. They’re one of the few freshwater species that will consistently eat fruit, seeds, and terrestrial insects, making them a fascinating topwater target.

In places like Corrientes and Santa Fe, anglers target pacú on fly or light tackle near overhanging branches, back eddies, or current seams where food collects. Surface takes are often slow and deliberate, but once hooked, pacú use their broad bodies and powerful tails to pull deep into cover, requiring precision and patience to land.

Where to Find Pacú

Corrientes – Jungle rivers and oxbows with sight-fishing potential

Corrientes offers excellent pacú fishing in slow-moving river sections and oxbow lakes. Fly anglers often target them near fruiting trees or flooded banks, especially in the Upper Paraná basin. The region’s warm climate and abundant cover create ideal pacú habitat.

Santa Fe – Backwaters and woody structure along the Paraná

In Santa Fe, pacú are targeted near submerged logs, bank overhangs, and quiet side channels. Both fly and spin fishing are productive, particularly during lower water periods when sight-casting becomes possible.

Northern Argentina – Remote rivers and productive tributaries

Beyond Corrientes and Santa Fe, provinces like Chaco and Formosa offer remote river fisheries with strong pacú populations. These areas are less developed for international anglers but support healthy, lightly pressured fish.

Paraguay – Productive stretches of the Paraguay River basin

Pacu are widespread in Paraguay, especially along slow-flowing reaches of the Paraguay and Paraná Rivers. Overhanging fruit trees and oxbow backwaters offer ideal feeding zones.

Bolivia – Clear jungle rivers and fly-friendly structure

While better known for golden dorado, some Bolivian rivers also hold pacú. Sight-fishing opportunities exist in clear, jungle-fed systems with the right seasonal flow.

Brazil – Amazon tributaries and the Pantanal wetlands

Brazil is home to several pacú species, with productive fishing in both the Amazon basin and Pantanal. They are often caught in tannin-stained backwaters or flooded forest margins, particularly during seasonal high water.

What Makes Pacú Special?

What sets pacú apart is their feeding style. They’re one of the few freshwater species that regularly eat fallen fruit, nuts, and insects on the surface—allowing for true topwater sight-fishing. Their fight is strong, sustained, and often close to cover, making every fish a challenge. The combination of visual eats, unique diet, and thick-bodied resistance makes pacú one of South America’s most interesting river targets.

What Do Pacú Look Like?

Pacú have a deep, laterally compressed body, often rounded like a plate, with blunt heads and strong jaws. Their color varies from silvery to bronze, with darker fins and occasional reddish tones near the belly or pectorals. Their broad, square tail and muscular build make them powerful fighters in tight quarters. Mature fish often exceed 10 pounds, with some reaching over 20 in prime river systems.

Pacú Fishing Techniques

• Fruit and Seed Imitation Flies – Use foam or cork-bodied flies resembling berries or nuts. Present them under trees or in current seams with a dead drift.
• Terrestrial and Hopper Patterns – Insects are also part of the pacú diet. Large ant or beetle imitations work near overhanging banks.
• Spin Fishing with Soft Baits – Small, natural-colored soft plastics or surface lures can trigger strikes when retrieved near cover or along drop-offs.
• Quiet Presentation is Key – Pacú are wary and often spook easily. Soft casts and minimal disturbance are critical, especially in clear or low water.

Best Time to Fish for Pacú

• Corrientes – Best from November to March, when rising temperatures and fruit drop trigger active surface feeding.
• Santa Fe – Peak season is also November to March, with low water and stable flows concentrating fish near cover.
• Northern Argentina & Paraguay – Late spring through early autumn (October to March) is ideal. Feeding increases during periods of fruit fall and stable water conditions.
• Bolivia – Best during the low-clear water season (typically May to October), depending on the river system and rainfall.
• Brazil – Seasonal activity varies by region, but the high-water phase (December to April) often aligns with fruiting cycles in the Amazon and Pantanal wetlands.

Pacú are highly responsive to fruiting trees, water clarity, and floodplain conditions. Timing your trip to coincide with falling fruit, stable river levels, and low turbidity will significantly improve your chances of surface eats and sight-fishing opportunities.
