Study on the Application of Bdellovibrio bacteriovorus in the Aquaculture of Scophthlmus maxims
摘要
Abstract
[ Objective ] By using Bdellovibrio bacteriovorus to promote the growth of Scophthlmus maxims,enhance the survival rate and eliminate the vibrios in aquaculture water. [ Method] Combining 20 d water exchange cycle,one group as the control (B group)and one group as adding Bdellovibrio bacteriovorus ( C group ) ,while with the ponds of production as reference ( A group) . Then,taking survival rate,weight gain ,average daily weight incroment,body length growth rate,average daily growth rate in body length and fat factor as the judgment to determine the effect of Bdellovibrio bacteriovorus in the growth of Scophthlmus maxims. Besides, the number of vibrios in seawater of each group was detected during the period of experiment ( the moment before and after c hanging seawater). [ Result] The results showed that the values of growth indexes of the group of adding Bdellovibrio bacteriovorus were obviously higher than that of the production and the control groups( P ＜ 0. 05 ). Compared to the production group, the survival rate increased by 13.23％, while weight gain,average daily weight increment, body length growth rate,average daily growth rate in body length and fat factor increased by 663％ ,130. 35 mg,28.09％ ,31.82 μm and 4.99 respectively. Vibrios were obviously reduced in the group of adding Bdellovibrio bacteriovorus. [ Conclusion] Bdellovibrio bacteriovorus has the effect on the growth and the survival rate of Scophthlmus maxims,also can ehminate the vibrios aquaculture.关键词
