Background

The annual output of marine economic shellfish culture in China is about 1480 ten thousand tons, which accounts for 69 percent of the total output of marine culture, and has important economic status. The shellfish culture process is generally divided into a planktonic larva culture period, a juvenile shellfish intermediate culture period and a adult shellfish culture period. The death rate of young shellfish with shell length less than 1 cm when being put into the sea area is high, so the intermediate cultivation (the young shellfish is cultivated to the suitable specification for sea area cultivation) is a necessary stage of the whole cultivation process. At present, the juvenile mollusk intermediate culture mode in China is extensive and can be divided into indoor cement pond culture, outdoor soil pond culture and marine intermediate temporary culture, and the defects of large occupied area, low culture density, large labor amount for labor operation, high juvenile mollusk death rate and the like exist.

The method floats the young shellfish by a sufficient water flow to prevent the extrusion of the adjacent young shellfish, so that the young shellfish can be stacked layer by layer without causing poor growth. And the ascending water flow brings the excrement of the young shellfish out of the system, thereby solving the problem of the sediment of the excrement of the young shellfish. The larvae of oysters cultured by the upflow system have low mortality, good growth condition and high culture density. However, foreign upflow devices need to be customized, and have complex structures and higher cost.
