bahía san blas — isla del jabalí
Fishing village on an island within the Bahía San Blas reserve, at the southern tip of Buenos Aires province. Croaker, pescadilla and large sharks, always released.
Bahía San Blas sits on Isla del Jabalí, in Patagones district, inside a provincial reserve of islands, estuaries (rías), sandbanks and marshes. The village began as a fishing colony and, since the 1960s, has become one of the province's sport-fishing centers. In front of the village the shore is pebbly and the bottom drops off quickly; to the south, sandy beaches offer varied fishing for croaker (corvina rubia), pescadilla (whiting), gatuzo, rays and pez palo. By boat, trips head to the front of Isla Gama and to the channels between the islands. Large sharks enter the bay and are caught only for release: escalandrún (sand tiger shark, Carcharias taurus), bacota (copper shark, Carcharhinus brachyurus), with many juveniles, and gatopardo (sevengill shark, Notorynchus cepedianus), which uses Bahía Anegada as a nursery. In the ría of the Jabalí stream, on a rising tide, you can catch pejerrey and flounder (lenguado).
best season
From spring to the end of summer, October to March, with warmer water and coastal sharks in the bay. On the sandy beaches south of the village, cazón usually shows up from September to December.
Local rules: Buenos Aires Province sport fishing license required. Under the marine regulation (Disp. 217/07), escalandrún, bacota, gatopardo, cazón and hammerhead shark must be released: one rod per boat angler, two from shore, a single circle hook and line of 0.70 mm or more. Mixed catch up to 40 fish per day; black drum, rays and pez ángel no more than 2; corvina rubia at least 35 cm and pescadilla at least 30 cm. The bay is a Multiple-Use Natural Reserve (Law 12.788): sport fishing is allowed but may be suspended. Check local rules.

before you fish in Argentina
There is no national license: the sport fishing license belongs to each province. In northern Patagonia, the Patagonian Regulation permit issued by Neuquén, Río Negro, Chubut or the National Parks Administration (APN) is valid in all these jurisdictions, including the southern parks; in 2025/2026 it cost $40,000 per season for residents of the country and from $50,000 (day) to $280,000 (season) for non-resident foreigners, with online purchase. Santa Cruz and Tierra del Fuego have their own permits (TDF 2026/2027: foreigners from $78,000 per day to $260,000 per season). On the coast (Buenos Aires, Entre Ríos, Corrientes) each province issues its own.
- The license is provincial. In Patagonian national parks, the APN permit or the provinces' Patagonian permit is valid, and fishing is only allowed in the environments listed in the parks' annex.
- Patagonian Regulation (2025/2026): general season from November 1 to May 1; in rivers and streams, including 200 m from their mouths, mandatory release with a single barbless hook, except for exceptions in the annexes; as a rule, one artificial lure with a single hook; selling fish prohibited; felt-soled boots prohibited.
- In national parks, all native species (perch, Patagonian pejerrey, catfish, peladillas) must be released; Atlantic salmon must be released in all environments under the regulation.
- Golden dorado: in Corrientes it is a Provincial Natural Monument (Law 6,730/2025); in Entre Ríos commercial fishing is prohibited and sport fishing is catch-and-release only (Law 11,174/2024); on the Uruguay River, shared with Uruguay, there's a CARU closed season from September 1 to December 31.
