How to start raising shrimp? Do you have any skills to raise shrimp?

Experienced shrimp farmers (white shrimp, Macrobrachium rosenbergii, freshwater crayfish) will use EM bacteria to regulate and stabilize the water quality of shrimp ponds, and even use EM bacteria for sterilization and disinfection. EM bacteria are safer than other fishery drugs, and prawns have no side effects. EM bacteria are mainly composed of various probiotics, such as photosynthetic bacteria, Bacillus, bacteria, nitrifying bacteria, lactic acid bacteria, yeast and so on. EM bacteria are directly used to spread the pond, killing miscellaneous bacteria and germs in the shrimp pond and purifying the water quality through mutual phagocytosis among bacteria. EM bacteria can effectively control the contents of nitrite and ammonia nitrogen in shrimp ponds and stabilize the PH value. In addition, EM bacteria can ferment animal manure and bean curd residue to feed shrimp fertilizer and water. Using EM bacteria to adjust water regularly can promote the growth of beneficial algae, make the shrimp pond keep algae phase stable for a long time, have high water transparency and sufficient dissolved oxygen, and double the water changing time.

Special efficacy of aquatic EM strain in shrimp culture

1. Adjusting the micro-ecological environment in the shrimp pond: the number of beneficial microorganisms in the shrimp pond increases, killing and inhibiting harmful microorganisms, increasing the number of beneficial microorganisms, increasing the number of zooplankton and beneficial algae on the water surface, maintaining the number of probiotics in the shrimp pond at a high level, and gradually forming a beneficial micro-ecological environment.

Secondly, reduce pathogenic microorganisms and unhealthy algae, obviously enhance the immunity and disease resistance of shrimp, improve the survival rate of shrimp, reduce the incidence of common diseases (black gill disease, limb rot, water mold and edema caused by Pleurotus ostreatus), and basically do not use drugs throughout the shrimp culture cycle.

Thirdly, the excess bait and shrimp manure are decomposed by EM bacteria and will not be deposited in the bottom of the pond in the form of sand. The PH value of the shrimp pond is kept weakly alkaline (7.5-8.5), and the excess organic matter in the water is decomposed for plankton to eat, thus stabilizing and improving the water quality of the shrimp pond. The water body is bright in color, free from corrosion and peculiar smell, and the visibility is prolonged by 25-45cm, and the water changing time is prolonged by more than 1 times.

Fourth, promote the growth of shrimp, improve the weight gain rate and yield. Practice has proved that, in the same shrimp culture environment, after using the EM bacteria of Nongfukang, it can be listed 10 days in advance, and the average yield per mu can be increased by more than 20%.
