In recent years, the application of microbial technology in aquaculture has become more widespread. Microbial technology has the advantages of small investment, large profits, no drug resistance, non-toxic side effects to fish, no residual pollution, etc. The use of microbial preparations for aquatic aquaculture, and the realization of pollution-free breeding, has become a development trend. Then, what are the things that need attention in the use of microbial agents? The use of probiotics should have a sufficient concentration, and to continue to use to play a good effect. The role of microbial agents is mainly achieved through competitive inhibition with other microorganisms. Therefore, the first use and replacement of litter must be sufficient when used, and adhere to long-term continuous use in order to achieve the best results. However, it is not the use of a larger dose, the better, and the amount of microecological preparation used as an immunopotentiator in the feed should not be large, and it can be added in small amounts for continuous use. It should not be mixed with antibiotics, disinfectants and pesticides. Since antibiotics, disinfectants, insecticides, etc. will affect the proliferation of microorganisms in different degrees, they should be replaced with clean water as much as possible before the application of microbial preparations, and they should be used continuously to form a dominant group of microorganisms. Establishing a dominant position and reaching a new equilibrium will show the effect of preventing disease and purifying water. If you start using antibiotics, disinfectants, and pesticides within 3 to 5 days after use, you will lose all your energy. Mixing orally must be aware of whether there are antibacterial ingredients in the feed additive. The use of microbial preparations should take into account the environmental conditions. Microbial microorganisms in microbial preparations require certain environmental conditions for growth and reproduction. Therefore, they should be used according to the ecological characteristics of various microbial preparations. For example, photosynthetic bacteria must have a certain amount of light, humidity and temperature to grow and reproduce. Therefore, photosynthetic bacteria should not be used on cloudy days, rainy days and nights. They should be used on sunny days. Pay attention to the viability and quantity of microbial preparations. Microecological preparations must contain a certain amount of live bacteria, and generally require more than 300 million viable cells per milliliter, and have a strong vitality. Should be stored at room temperature, cool, and pay attention to the preservation period of the probiotics. With the extension of the preservation time of the preparation, the number of live bacteria gradually decreases, which means that its role is getting smaller and smaller.
