In order to raise the seedlings of the clams, the seedlings of clams of 0.5-1.0 mm in size are gradually cultivated into 50-70 seeds per 500 g seedlings. In the first stage, 0.5-1.0 mm seedlings are grown into 0.8-1.5 cm seedlings. After screening, they are evenly dispersed and cultivated into suitable seedlings of about 3 cm in size. The benthic diatoms can grow quickly and the water level increases as the water temperature rises. The specific gravity is maintained at 1.010-1.017, and the pool water is slightly dark brown with diatoms.
