Fishing in Entre Ríos

Entre Ríos sits in the Argentine Litoral, a province literally defined by water — bounded on the west by the Río Paraná and on the east by the Río Uruguay, with a web of rivers, arroyos, and lakes filling the space between.

The name means "between rivers," and the fishing scene lives up to it. This is warm-water country: big, slow-moving channels, flooded delta systems, and oxbow lagoons, not mountain trout streams.

The target species that draws most visiting anglers here is the golden dorado. The Río Paraná is the backbone of the fishery.

Its delta system in Entre Ríos is the second largest in South America after the Amazon — a maze of channels, islands, and backwaters where dorado average around 2–3 kilograms but fish in the 7–9 kilogram range show up regularly.

Spinning, bait casting, and fly fishing all work here, with big streamers on sinking lines being the standard fly approach. The Paraná Guazú is another productive stretch worth knowing.

Towns like Hernandarias, Piedras Blancas, La Paz, and Santa Elena anchor the so-called Ruta del Dorado along the Paraná corridor, giving anglers a string of access points running roughly north to south through the province.

Puerto Yeruá, on the Río Uruguay side, has a reputation specifically for surubí — the large spotted catfish that shares these waters with dorado.

Concordia, also on the Uruguay, sits near Lago Salto Grande, a reservoir that adds another dimension to the fishing in the northeast of the province.

The Río Gualeguay cuts through the interior, and smaller waters like Arroyo Ayuí Grande and Laguna Brava Grande fill out the options away from the main rivers.

Fishing runs year-round, but the Litoral comes into its own from spring through summer — roughly September through March in the southern hemisphere. Catch-and-release programs are well established here, particularly for dorado, and worth seeking out.

A fishing license is required by law for all anglers, including foreign visitors; check current rules and bag limits with the provincial authority before you go, as these are updated each season.

Trolling and spinning dominate among local anglers, but fly fishing for dorado has grown steadily, and the infrastructure — guides, live-aboard operations on the Paraná delta, dedicated fly programs — reflects that.

Come with wire or heavy fluorocarbon for the dorado's teeth, sunscreen, and serious mosquito repellent. The fish are real. So are the insects.
