东风螺水泥池养殖两种铺沙方式的比较

摘要

In order to create an economic and efficient bottom environment of aquaculture Babylonia in cement pond, two meth- eds of sanded sediments on bottom were tested to compare the results of farming Babylonia. The results showed that there was no significant difference in growth between b. aerolata and B. formosae habei under the same sanded way, the similar breeding water temperature and the close breeding density conditions in different years of the same season. When the methods of sanded sedi- ments were sanded above the bottom, that the average daily growth rate of b. aerolata and B.formosae habei, was 85.0% and 68.6% respectively, higher in body weight than using those of ways that sands were att~ed to the bottom, the average daily growth rate was 56. 1% and 45.4% respectively higher in shell height than those in the way. The methods of sanding above the bottom were effective technological measures of Babylonia aquaculture to build economic, efficient sediment environment in ce- ment pond.%为营造东风螺水泥池养殖经济、高效的底质环境，进行了水泥池两种铺沙方式东风螺养殖效果的比较试验。结果表明，在不同年份的相同季节，养殖水温无明显差异，养殖密度大致相同的情况下，同一铺沙方式方斑东风螺（B.aerolataLink）和波部东风螺（B．formosaehabei）的生长无明显差异。而离底铺沙，方斑东风螺和波部东风螺的体重日均生长速度分别比贴底铺沙高85．0％和68．6％，壳高的日均生长速度分别比贴底铺沙高56．1％和45．4％。离底铺沙是东风螺水泥池养殖构建经济、高效底质环境的有效技术措施。
