Top Pacific Cupped Oyster Fishing Countries

The Pacific cupped oyster (Crassostrea gigas), also known as the Japanese oyster, is a hardy, fast-growing bivalve native to the Pacific coast of Asia but now widely farmed around the world due to its adaptability and high market demand. This species is a cornerstone of global aquaculture, prized for its mild flavor and versatility, and is typically cultivated using rack, bag, or longline systems in intertidal and subtidal zones. The leading producers of Pacific cupped oysters are China, Japan, and South Korea, with China dominating global production by a wide margin, accounting for over 80% of the world's supply. France is the top European producer, where the species supports a significant aquaculture industry, especially along the Atlantic coast. The United States, particularly the Pacific Northwest, also contributes notably to global harvests. The Pacific cupped oyster industry is vital for coastal economies, providing employment and supporting local communities, though it faces challenges such as disease outbreaks and environmental changes.
