Abstract: In order to create a economic and efficient sediments aquaculture Babylonia in cement pond, two methods of sanded sediments on bottom were tested to compare the results of farming Babylonia. The results showed that the growth of B. aerolata and B.formosae habei was not significant difference same way sanded,under the breeding water temperature and the stocking density similar cases in same season different years. When the methods of sanded sediments were left the bottom sanded, that the growth rate of body weight daily of B. aerolata and B.formosae habei, was higher than which affixed to the bottom sanded 85.0% and 68.6%, the growth rate daily of shell height was higher than it 56.1% and 45.4%. The methods of leaving the bottom sanded sediments was effective technological measures of Babylonia aquaculture to build economic, efficient sediments in cement pond.
