Indispensable Oyster production in Hong Kong and China
China is the largest oyster producer in the world accounting for more than 80% of production. As there is increasing human population growth and economic development, and consequently increasing seafood demand with limited fishery production, oyster aquaculture is a sustainable way to supply the expanding demand for seafood. Thus, oyster aquaculture production in South China and Hong Kong is globally important and indispensable.
One-third of the oysters produced are Hong Kong Oysters (Crassostrea hongkongensis), and it is the major species cultivated in South China and Hong Kong. It is one of the most important cultured oyster species with high market value of 1.5 - 1.8 billion US dollars. Respective products of the Hong Kong Oysters such as shucked, canned, dried, power, calcium, and oyster sauce are very popular especially in Hong Kong, Macau and Taiwan.
