Arcade is the place in Pontevedra province where the most oysters are sold, and the town's name is attached to the Galician flat oyster. The oysters themselves are now grown on rafts in the outer Ría de Vigo. Culture in the inner ría, at Arcade's door, was lost decades ago.1

Ostreares

On 21 August 2026 Galicia's sea ministry, the Arcade fishermen's guild and the regional marine research centre at Ribadeo laid 103,500 seed of the European flat oyster in the Enseada de San Simón, the inner bay. The seed was raised by the research centre. The work is part of a project called Ostreares, running from 2024 to 2027 with European maritime and fisheries funding, to restore the oyster and the sand flats it lives on.1

The same species is being rebuilt across Europe, as described in our piece on flat oyster restoration. Galicia's raft-grown oysters are covered in the Ría de Arousa profile.

Flavor Breakdown

First
Salt, with little sweetness. Our scores put brine at three and sweetness at two.
Then
Minerality at four, with the metallic finish of the species.

What Makes Arcade Unique

A town famous for an oyster it stopped growing, now putting that oyster back in its own bay, a hundred thousand seed at a time.1

Eat it in Arcade, the town that sells more oysters than any other in the province. Ask whether yours came from the rafts or, in a few years, from San Simón.

Should You Add Lemon?

Cautiously

The finish is the point of a flat oyster. A few drops at most.
