Problems solved by technology

There are very few types of microbial preparations for aquaculture, and there is a serious lack of microbial preparations suitable for freshwater shrimp. At present, some aquaculture enterprises put antibiotics into the breeding ponds, and the antibiotics have a bactericidal effect. Time use will reduce water quality and affect the growth of freshwater shrimp

Abstract

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.

Description

technical field [0001] The invention relates to a biological agent, in particular to a biological agent for freshwater shrimp cultivation. Background technique [0002] With the rapid development of the aquaculture industry, especially the vigorous development of industrialized high-density farming today, cultivating a good breeding environment, improving production efficiency, and reducing production costs have become important conditions for aquaculture. [0003] Domestic and foreign studies have found that marine algae are rich in polysaccharides, which have good activity as anti-disease drugs, can improve the immunity of animals, and have the characteristics of low toxicity and low drug resistance. There are very few types of microbial preparations for aquaculture, and there is a serious lack of microbial preparations suitable for freshwater shrimp. At present, some aquaculture enterprises put antibiotics into the breeding ponds, and the antibiotics have a bactericidal e...
