Current Status, Challenges, and Recommendations for the Shellfish Industry in Qingdao

The shellfish industry constitutes a vital component of Qingdao's marine economy, renowned for its long history and diverse species including clams, oysters, and scallops. This study systematically analyzes the current development status and prominent challenges facing Qingdao's shellfish industry based on data from the city's aquaculture germplasm resource census, regional aquaculture statistics, and representative case studies. It proposes targeted development strategies. Findings indicate that Qingdao's shellfish industry has achieved steady growth in total output, establishing an industrial structure dominated by clams, oysters, and scallops. This sector has also produced a number of superior varieties and renowned brands, including “Haida 1-4” and “Hongdao Clam.” However, the industry's sustainable development faces severe challenges, including intensified ecological pressures in aquaculture zones (such as overcapacity farming and starfish blooms), frequent marine disasters, an incomplete industrial chain, and low product value-added. Therefore, this paper proposes that aquaculture activities should be scientifically assessed and planned around the core principle of “determining scale by capacity”; strengthening seed industry system construction and protecting local germplasm resources; promoting the industry's transition towards green, efficient, and facility-based operations; and enhancing market competitiveness through deepening processing and brand building. This study aims to provide theoretical foundations and practical references for the high-quality development of the shellfish industry in Qingdao and similar coastal regions across China.
