As a major country in the cultivation of burying shellfish such as clams and razor clams,China's technology and equipment level in the harvesting process are directly related to the sustainable development of the industry. To enhance the sustainable development of the burying shellfish aquaculture,this study systematically reviews the mainstream shallow sea burying shellfish harvesting equipment(drag rake type,hydraulic type,rotary tooth type,propeller type,and vibration type) at home and abroad,analyzes their working principles,structural characteristics,and harvesting effects. By comparing the current research status of shallow sea shellfish harvesting equipment at home and abroad,this study reveals the bottlenecks of weak theoretical mechanism research,lack of ecological impact assessment,insufficient specialized design,and lagging intelligent control in domestic equipment. Propose a targeted independent research and development path:deepen the theory of fluid solid coupling in the harvesting process,and develop harvesting equipment suitable for China  s shallow sea bottom-sown mode ;Building an ecological benefit oriented“ harvesting restoration”collaborative system; Promote the integration of mechanization and intelligence technology,achieve precise control and visualization of harvesting trajectories,and provide technical support for breaking through industrial constraints and promoting green aquaculture.
