在泥蚶养殖水体中(1000L)投喂浓度分别为1、5和10g微生态制剂(芽孢杆菌),在30天的投喂期内,采用平板计数法检测底泥中、泥蚶体内的细菌总数和弧菌总数。结果表明,在投喂冻干菌粉后,养殖底泥和泥蚶体内菌群在前7天均呈明显上升趋势,7～30天内缓慢下降。由于芽孢杆菌的抑制作用,弧菌的数量下降,以泥蚶体内的弧菌最明显。芽孢杆菌对养殖底泥和泥蚶体内的细菌菌群影响很大,芽孢杆菌对养殖水体底泥和体内菌群的影响与抗生素具有相近的效果,表明芽孢杆菌作为饲料添加剂可以取代抗生素应用于泥蚶养殖。
Sludge breeding water (1000L) were fed concentrations of 1,5 and 10g probiotics (Bacillus), in the 30-day feeding period, the use of plate count method to detect bacteria in the mud sediment The total number and the total number of Vibrio. The results showed that after feeding the freeze-dried powder, the growth of the bacteria in the bottom of the sediment and mud in the first 7 days showed a clear upward trend, 7 to 30 days decreased slowly. Due to the inhibitory effect of Bacillus, the number of vibrio decreased, the most obvious vibrio in the mud. The effect of Bacillus on the bacterial flora in the culture sediment and muddy clay is very significant. The effect of Bacillus on the sediment and body flora of the cultured water is similar to that of antibiotics, indicating that Bacillus can be used as a feed additive instead of antibiotics in mud蚶 breeding.
