Top South American Rock Mussel Fishing Countries

The South American rock mussel, scientifically known as *Perna perna*, is a bivalve mollusk native to the Atlantic coasts of South America, particularly thriving on rocky shores and intertidal zones. This species is valued both for local consumption and export, playing an important role in the regional seafood industry. The leading countries in harvesting the South American rock mussel are Brazil, Uruguay, and Argentina. Brazil stands out as the top producer, with extensive aquaculture operations along its southern and southeastern coasts, where the warm waters and suitable substrates support large mussel populations. Uruguay and Argentina also maintain significant fisheries, with artisanal and small-scale commercial harvesting contributing to local economies and traditional diets. The industry in these countries is characterized by a mix of wild collection and aquaculture, with ongoing efforts to ensure sustainability and improve yields through scientific research and management practices.
