Which brand of aquatic EM strains are effective for shrimp farming? How to buy

Which brand of aquatic strains special for shrimp farming is effective? How to buy
In recent years, my country's aquaculture industry has become more and more developed, and the breeding technology has become more and more mature, so the shrimp farming technology is also very complicated. Many shrimp farmers may have questions like this: Is it better to use bacterial biological agents to raise shrimp, or is it better to use single bacteria such as nitrifying bacteria, Bacillus, and photosynthetic bacteria? What is the difference between bacteria and single bacteria?
Bacteria and single bacteria have their own advantages and disadvantages. The comprehensive effect of bacteria is far better than that of single bacteria, such as regulating water quality stability, while the single effect is not as good as that of single bacteria, such as reducing nitrate. So you have to have both, each is indispensable. What are bacteria? Bacteria are a collection of dozens of single bacteria such as Bacillus, nitrifying bacteria, photosynthetic bacteria, lactic acid bacteria, and yeast. From this we can also see some of the advantages and disadvantages.
Then some customers may have questions about which one is the best with so many bacteria on the market? What kind of bacteria are good? What kind of bacteria are produced by major manufacturers? What kind of bacteria are most effective? Then there are the following standard bacterial activities. Simply put, it is the speed at which bacteria divide. We all know that bacteria divide and grow, grow, grow, grow, and divide like this. So sometimes we can't just look at the bacterial content, but I was deceived by those small workshops that falsely continued the process. Regarding the activity of bacteria, many customers may not be able to define it, but they can also pass the test. Is it the first-generation protobacteria? Generally, the first-generation protobacteria need to be activated for use. Generally, the first-generation protobacteria are clean and highly active. Whether the manufacturer is formal and has various certificates. I hope all interested people will choose carefully.
Nongfukang aquatic strains have been produced since the establishment of Nongfukang. Nongfukang aquatic strains are rich in lactic acid bacteria, yeasts, Bifidobacteria, Bacillus, nitrifying bacteria, photosynthetic bacteria and other genera and species of microbial probiotics. The first-generation protobacterium from Yu Nongfukang Laboratory has strong activity and good effect. Please contact WeChat for details

br Usage and dosage of Nongfukang’s special aquatic strain for shrimp farming
Nongfukang’s aquatic strain requirements It can be used after activation. The activation method is to ferment the special strains for bottle shrimp culture + kilograms of brown sugar water. The fermented product is the aquatic bacteria liquid
Water quality control
The day before stocking, dilute it with Nongfukang aquatic bacteria liquid Splash the water. Depending on the water quality, start once a day and then once a month. In areas with poor water quality, shorten the splashing time appropriately. In order to spray evenly, first dilute the Nongfukang aquatic bacteria liquid twice before use. For water depths of 1 meter and below, kilograms of bacterial solution should be used per acre. It is usually released in the morning on a sunny day.
Direct mixing and feeding
If you want to mix Nongfukang aquatic bacteria liquid into the feed and feed it, you can add Nongfukang aquatic bacteria liquid according to the weight of the feed. The specific method is as follows. To prepare kilograms of feed, take kilograms of Nongfukang bacterial liquid and add about kilograms of water to dilute it. Spray the diluted Nongfukang aquatic bacterial liquid while turning the bait. Mix evenly before feeding.
Benefits and functions of using aquatic bacterial strain mixture
It can reduce the feed coefficient, improve the absorption function of aquatic animals and disease prevention and stress emergency response capabilities, promote growth, significantly reduce the dosage of medicinal products, improve water quality, and improve the bottom of ponds , the water body is refreshing, neither rotten nor smelly, the visibility can reach 10 centimeters, and the water change time can be extended more than twice. Full use can significantly reduce drug costs by more than 1%. Adhering to the use of Nongfukang aquatic bacterial liquid throughout the entire process can greatly increase the survival rate, and the breeding cycle in similar environments can be launched days in advance, with obvious comprehensive benefits.
Bait fermentation
Commonly used fermentable materials include various types of residues, straw, grass, rice cakes, animal feces scraps, etc. The materials can be taken according to local materials. Nongfukang aquatic bacterial liquid kilograms fermentable feed kilograms are calculated based on the weight of dry materials.
The fermentation method is
Dilute the Nongfukang aquatic bacteria liquid with water, add kilograms of water, and then mix it evenly with the bait to be fermented, adjust the moisture to about 100%, then seal and start fermentation. The fermentation time is generally sky. The way to judge the humidity is to grab a handful of material with your hands and hold it tightly. If you see water stains on the seams of your hands, but no dripping, stand up and release your hands. The material will fall to the ground and spread out.

Disease prevention
If fish floating heads and pond flooding occur, Nongfukang aquatic bacteria solution can be diluted twice and sprinkled evenly on the water surface. It will improve in ~ hours and the fish will return to normal. After that, you can spray it again every other day. For individual fungal fish diseases, bacterial enteritis, gill rot, printing disease, etc., the diseased fish can be fished out, and Nongfukang aquatic bacteria liquid diluted to 100 times can be directly applied to the lesions, or the diseased fish can be soaked with Nongfukang aquatic bacteria liquid diluted to 100 times until the fish appears. Slight floating of the head will stop and it will be cured in a few days.
Fermented manure organic fertilizer and water
Common fermentation materials include various types of animal manure, plant stems, leaves, straw, grass powder, etc. Through fermentation, organic fertilizer can proliferate beneficial bacteria in large quantities, promote the reproduction of zooplankton, and avoid pollution of water bodies. The fermentation method is the same as the above-mentioned bait fermentation method. It is worth noting that if more animal manure is used, the dosage per acre should be kilograms, not too much.
Pond Treatment
A week before the shrimp pond is filled with water, kilograms of aquatic bacteria liquid per mu diluted to 100 times should be sprayed evenly. Kilograms of aquatic bacteria liquid per mu should be used instead of lime to disinfect and purify the pond.
