| 摘 要： | 将育苗用水经消毒及沉淀处理后作为试验基础用水,应用泡沫分离器、经预处理的生物滤器和紫外线消毒器等处理罗氏沼虾育苗循环水,使水质得到了有效控制。试验期间,对照池以大量换水及用药等传统方式维持水质,而试验池未曾用药和换水,较对照池节约水67.5%;试验池主要水质指标变化范围如下:NH3 Nm:0～0.010mg·L-1,NO2- N:0.01～0.63mg·L-1,pH:7.48～8.37,CODMn:5.42～12.25mg·L-1,细菌总数:(4.2～130)×103cell·mL-1,弧菌数:(0.2～20)×102cell·mL-1;试验组出苗率为40%,高出对照组33.3%。生产性育苗试验中,试验池与对照池均获得了30%的出苗率。据试验结果及罗氏沼虾育苗特点,提出了处理罗氏沼虾育苗循环水的技术与模式。

| Abstract: | The estuary water after being disinfected and deposited was used as foundational water in experiment.
The foam separator , pre2cultured biofilter and ultraviolet disinfector were applied to treat recirculating water in
breeding for Macrobrachium rosenbargii larva. The quality of recirculating water was controlled effectively by the
water treatment system. The water quality was controlled with traditional method in control pond , in which a lot
of medicine and water exchanging was applied ,so the amount of water in test pond with no medicine or water
exchanging was 67. 5 % less than that in control pond. The variety of main parameter of recirculating water in test
pond during the experiment were as follows : NH32Nm:0 -0.010 mg?L -1 ,NO2
2N :0.01 -0.63 mg?L -1 ,pH:
7.48-8.37,CODMn : 5.42 -12.25mg?L -1 , bacterium : (4. 2 -130) ?103cell ?mL -1, vibrio: (0.2 -20) ?
102cell?mL -1. The survival rate of experiment pond was 40 % , which was 33. 3 % more than that in control
pond. Good result was also obtained in the productive test , in which the survival rates of productive test pond and
control pond were both 30 %. The model on recirculating water treatment in breeding larva of Macrobrachium
rosenbargii is proposed according to the experimental result and breeding character of Macrobrachium rosenbargii. |
