In recent years, microbial technology has become more and more widely used in aquaculture. Because microbial technology has the advantages of small investment, large income, no drug resistance, no toxic side effects on fish body, no residual pollution, etc., the use of microbial preparations for aquaculture and aquaculture has become a development trend.
What are the needs of the microbial preparations in the process of use?
Guaranteed concentration, continuous use of
The role of microbial preparations is mainly achieved through competitive inhibition with other microorganisms. Only when beneficial microbial bacteria form a dominant flora in a suitable environment can the harmful microbial growth and reproduction be effectively inhibited. Therefore, the first use and replacement The amount of material used must be sufficient and adhere to long-term continuous use in order to achieve the best results. However, the microecological preparation is not used as the dose is as large as possible, and the microecological preparation used as the immunopotentiator is not added in the feed, and can be added in a small amount and continuously used.
not be mixed with antibiotics, disinfectants and pesticides.
Since antibiotics, disinfectants, insecticides, etc. all affect the proliferation of microorganisms to varying degrees, they should be replaced with clean water before use, and should be used continuously to form a dominant flora, and the beneficial bacteria in the microbial preparations Establishing a dominant position and reaching a new equilibrium will show the effect of disease prevention and water purification. If you start using antibiotics, disinfectants and pesticides within 3 to 5 days after use, you will lose your efforts. The internals of the mixture must pay attention to understand whether there are antibacterial ingredients in the feed additives.
Considering environmental conditions
Microbial bacteria in microbial preparations require certain environmental conditions to grow and multiply, and therefore should be used according to the ecological characteristics of various microbial preparations. For example, photosynthetic bacteria must have a certain light, humidity and temperature to grow and multiply, so photosynthetic bacteria should not be used on cloudy, rainy or nighttimes and should be used on sunny days.
Maintain microbial vitality and quantity
The microecological preparation must contain a certain amount of live bacteria, and generally requires more than 300 million living cells per ml, and the vitality is strong.
Pay attention to the preservation conditions
It should be stored at room temperature and in a cool place, and pay attention to the shelf life of microecological preparations. As the storage time increases, the number of viable bacteria gradually decreases, which means that its effect is getting smaller and smaller.
