Top Slipper Cupped Oyster Fishing Countries

The Top Slipper Cupped Oyster, scientifically known as *Crassostrea gigas* and commonly referred to as the Pacific oyster, is a bivalve mollusk prized for its rapid growth, adaptability, and culinary value. Originally native to the Pacific coasts of Asia, particularly Japan, this oyster species has become the cornerstone of global oyster aquaculture due to its resilience and high yield. The leading countries in harvesting the Pacific oyster are China, Japan, South Korea, and France. China dominates the industry, producing the vast majority of the world’s supply through extensive aquaculture operations along its eastern seaboard. Japan, with a long history of oyster cultivation, remains a significant producer, especially in Hiroshima Bay. South Korea has also developed a robust oyster farming sector, particularly in the southern coastal regions. In Europe, France stands out as the top producer, especially in Brittany and Normandy, where the Pacific oyster has largely replaced native species in commercial cultivation. The fishing and farming of the Top Slipper Cupped Oyster are vital to the economies of these countries, supporting local communities and contributing significantly to global seafood markets.
