Biological agent for freshwater shrimp aquaculture

The invention discloses a biological agent for freshwater shrimp aquaculture. The biological agent is prepared from bacillus subtilis, nutrient substances, photosynthetic bacteria, magnesium citrate,taurine and white carbon black. The biological agent has the beneficial effects that the bacillus subtilis can indirectly inhibit the reproduction and survival of harmful bacteria in an intestinal tract, adjust the imbalanced flora relation in the intestinal tract and keep intestinal flora to be normal, so that the effect of conditioning intestines and stomach and preventing diseases can be achieved; in the shrimp aquaculture process, by means of the biological agent the food ration of shrimps can be increased, the digestion and absorption functions of the shrimps can be enhanced, and the rapid growth of the shrimps can still be kept under the environment that the breeding density is relatively high. 本发明公开了种淡水虾养殖用生物制剂，包括枯草芽孢杆菌、营养物质、光合细菌、柠檬酸镁、牛磺酸和白炭黑。本发明的有益效果是：枯草芽孢杆菌可间接抑制有害菌在肠道内的繁殖和生存，调整肠道内失调的菌群关系，保持肠道菌群正常，从而达到调理肠胃
