The micro ecological water purification agent mainly contains various beneficial bacteria such as lactic acid bacteria, bacillus and so on, and can improve the immunity of the organism by improving the water environment, regulating the types of beneficial bacteria, inhibiting the propagation of harmful bacteria, and reducing the content of ammonia nitrogen and nitrite. The purpose of growth and prevention of fish diseases. The following is a case analysis. In early July 2006, fish disease occurred in pond No. 6 in our farm. Thirty to forty grass carcasses were dead in one day and the size was 60 fish per kilogram. Symptoms of sick fish showed black body, white fins, and skeletal fins. The lid was "open skylight", and some spots were congested in the silk thread. Microscopic examination of the silkworm had myxosporidium and trichoderma, especially in the former. The pond has an area of ​​3 acres and a water depth of 2 meters. The water is blue-yellow and has a layer of oil film. The transparency of the water body is about 15 centimeters. Wuzai Xiatang applies both semi-fresh pig manure. According to the disease, it was diagnosed as parasite rot disease, two boxes of trichlorfon (the drug is a mixture of trichlorfon and copper sulphate), and the next day four bags of dibromohydantoin (500 grams per bag), For two days, mix four yellow powders in the feed and feed them for 3 days. The number of dead fish decreased on the second day and the dead fish was completely stopped on the fourth day. However, after 78 days, the grass carp died again. The symptoms were similar to those at the beginning but only a few parasites were left. Estimated to be related to the water environment, the fresh pig manure itself was not fermented well. It is recommended to splash the detoxifying water 2 vats (5 kg). The next day, the oil film disappears, the water becomes a little lighter, and there are 78 or more deaths of grass carp. On the fourth day, the water becomes “fresh and refreshingâ€, which is in line with the quality of grass carp culture. Condition, dead fish stopped. Until the beginning of September, the whole pool was prevented once again, and no dead fish were seen by the end of December. In other fish ponds in my field, some splashed ammonia water purification treasures, and the effect was also very good. It was found through experiments that after the reaction of water purification treasure with water, floccules were formed first and then precipitated, thus achieving the purpose of purifying water quality. The floe is estimated to consist primarily of organic matter, inorganic contaminants, and residual drugs in the pool. Through the trial in 2006, it changed the traditional treatment and prevention practice of “insect killer disinfection†and started with a fundamental approach, striving to create an optimal living environment for the growth of fish. The production cost has been reduced and the benefits have been improved, laying a solid foundation for the pollution-free breeding of fish species.
