中文摘要：2006年4月23日～5月15日在浙江省绍兴官渡三角帆蚌养殖基地,用密网围成四个网箱,各网箱分别投放2L、4L、8L、0L(对照)生活污水,吊高30cm,定期检测各网箱中细菌、霉菌、放线菌、酵母菌四大类微生物,研究结果表明:在所用的生活污水浓度范围内,生活污水的浓度越高,三角帆蚌的生长越好;投放的生活污水能增加水体中的细菌数量,投放越多,细菌数量增加越大;水体防线菌和霉菌的数量随着投放污水量的增加而显著增加;生活污水的投放与否以及投放的量与酵母菌之间没有明显的关系;从研究中可以得出生活污水有利于三角帆蚌养殖水体中微生物的生存,有利于三角帆蚌的生长.

外文摘要：The experiment was carried on the breeding base of Hyriopsis Cumingii in Guandu Village, Shaoxing, Zhejiang Province from April 23 to May 15 in 2006. We prepared four cages. In each cage, we hanged 20 Hyriopsis Cumingii which the initial weight of about 190g, Crane 30cm high. Puting 2L.4L. 8L.0L （control） sewage into different cage. Testing the quantity of bacteria, Streptomyces, Actinomycetes and yeast in each cage regularly. The results showed that in the concentration of sewage, the Hyriopsis Cumingii lives in sewage with higher concentration grow better. The Hyriopsis lives in the sewage with highest concentration weights higher than the other treatment and control groups obviously. The sewage would increase the number of bacteria in the water. And the more sewage, the greater increase in the number of bacteria. With the increase in the volume of sewage, the number of bacteria and fungi in water increased significantly. Whether put sewage or not and the volume of the sewage has no obvious relationhip with the number of yeast. It can be drawn from the study that sewage benefits the survival of microorganisms in Hyriopsis mussel aquaculture waters, and is conducive to the growth of Hyriopsis Cumingii .
