微生态制剂对池塘鲤鱼生产性能的影响

Effect of Probiotics on Production Performance of Pond Carps

本实验采用复合枯草芽孢杆菌微生态制剂净水菌对当年繁殖的14g/尾建鲤、按照相同放养密度分别在6号池(0.22hm2)、4号池(0.19hm2)中开展了生产性能试验。结果发现:在尽量不换水的情况下,泼洒微生态制剂净水菌相比未泼洒净水菌的饲料系数降低7.1%~8.9%,经济效益高出2.18倍。

In this experiment, according to the same stocking density, the year of breeding 14 g/tail Jian carps which were respectively allocated in No. 6 pool （3.27 acres） and No. 4 pool （2.9 acres）, were treated with Compound Bacillus Subtilis pro biotics bacteria for determination of production performance. The result shows that in the condition of not changing water as much as possible, compared with non-sprinkling water purification bacteria, the feed coefficient of the sprinkling of probiotics decreased 7.1-8.9% and the economic efficiency is 2.18 times higher.
