Abstract：A total of 457 thousands of juvenile snail Babylonia aerolata were cultured in 35 indoors cement ponds of each 30m~2 at 11 size classes and 7 stocking densities for 151～216 days in 2005. Totally 2574.9 kg of snail about 146 individual/kg(115～192 ind./kg)were harvested at a rate of 2.5 kg/m~2 (1.2～4.2 kg/m~2), with average survival rate of 82.2%(48.4%～97.8%)and food conversion ratio of 2.6. There were high and stable survival rate(above 86.5%)at stocking density of 870～9200 ind./kg, while lower survival rate at stocking density of above 12170 ind./kg. The survival rate was only 48.4% at stocking density of 23400 ind./kg, and constantly high at stocking density of 185.6～868.2 ind./kg. However, the growth rate significantly decreased at stocking density of over 542.6 ind./kg.
