Fishing in Parque Nacional do Superagui

Parque Nacional do Superagui sits on the northern coast of Paraná, where the state borders São Paulo, and it is built almost entirely from water.

The park's roughly 34,000 hectares take in Superagui Island, Ilha das Peças, Pinheiro and Pinheirinho islands, the Rio dos Patos valley, and the Canal do Varadouro — a mosaic of estuaries, mangroves, tidal channels, salt marshes, and open bays that drains into the larger Lagamar system connecting Paranaguá to Iguape.

There are no roads in. Every access point is by boat, which is part of why the water here has stayed as productive as it has. The fishing that draws most attention happens in the tidal channels and bay margins.

Baía dos Pinheiros is the main open-water body anglers work, with channel edges and current transitions that concentrate robalo-flecha (snook) during the incoming tide, particularly through autumn and winter — roughly April through September.

Fish over 10 kg have come out of these waters. Plugs in the 10–15 cm range in silver, white, or natural green, worked with firm strips and short pauses, are the standard approach along channel edges where current is strongest.

The Rio dos Patos valley, included within the park's boundaries, adds freshwater and brackish habitat to the mix.

The mangrove margins throughout the park hold snook early in the morning on neap tides, best approached quietly — by paddle or electric motor — with live shrimp under a running float.

Pescada-amarela (weakfish) move through the deeper channels, 10 to 20 meters, during spring and summer on an outgoing tide, responding to jigs in the 30–50 g range worked close to the bottom.

Fishing inside the park is permitted only in designated areas outside the core protected zones, and the caiçara communities within the park have their own traditional fishing practices that predate the park itself.

ICMBio administers the park, and current rules on where sport fishing is allowed, what gear is permitted, and any required documentation should be confirmed directly with ICMBio before you go — regulations in protected areas like this one can change, and the boundaries between permitted and restricted water are not always obvious on the water.

The boat-only access keeps pressure low, but it also means you need to know where you're going before you leave the dock. The place rewards anglers who come prepared and fish it carefully.
