Problems solved by technology

[0003] With the increase of demand in the aquatic product market and the urging of huge profits, a large number of antibiotics have been used in aquaculture to control pathogenic bacteria and reduce the mortality rate of aquaculture. This has caused the pollution of antibiotics in offshore aquaculture areas and seriously affected the development of offshore areas. ecological balance
In addition, aquatic products raised with antibiotics exceeding the standard flow into the public's dining table, which also causes potential harm to the human body
At the same time, the problem of antibiotics has also caused a great loss to the aquaculture industry. Therefore, both at home and abroad are looking for an effective method for ecological farming and reducing the mortality rate of aquaculture.

Abstract

The invention relates to the field of microbes, and particularly discloses a microbial composition and application thereof. The microbial composition comprises Saccharomyces cerevisiae and Bacillus, wherein the ratio of the viable count of the Saccharomyces cerevisiae to the viable count of the Bacillus is 1:(1-1000). The experiment indicates that the microbial composition has the functions of regulating the aquiculture water body quality, increasing the aquiculture weight gain rate and feed coefficient and lowering the aquiculture death rate. The microbial composition can be prepared into a veterinary medicine, feed additive or water quality purifying agent for independent use, can also be blended in aquatic animal feed to be directly fed, has wide application range, and has favorable economic and social effects.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a microbial composition and its application. Background technique [0002] Aquatic products are a general term for animals and plants produced by marine and freshwater fisheries and their processed products, including various sea fish, river fish and other aquatic animals and plants, such as shrimp, crab, clam, sea cucumber, jellyfish and kelp, etc., which are delicious. It is a popular dietary product and rich in nutrition. Fish, shrimp, crab, etc. are rich in protein, the content can be as high as 15% to 20%, and shark fin, sea cucumber, scallop, etc. contain more than 70% protein. In addition, the essential amino acid composition of fish protein is similar to that of meat, so its physiological value is high and it is a high-quality protein. The muscle fiber of fish meat is relatively slender, the tissue protein structure is soft, and the water content is relatively high, so the...
