AI Technical Summary

Technical Problem

In existing technologies, the deterioration of water quality in shrimp farming leads to an imbalance in the microbial ecosystem and intestinal flora, which easily causes diseases. Furthermore, the use of antibiotics leads to drug resistance and health risks, and there is a lack of effective disease-resistant and growth-promoting microbial agents.

Method used

The BG12 strain of *Actobacter spp.* from the intestinal tract of shrimp, which has amylase and cellulase activities, was used to prepare a probiotic additive to regulate the intestinal flora and improve immunity and disease resistance.

Benefits of technology

It improves the growth and disease resistance of shrimp, maintains the microecological balance of the aquaculture system, reduces the risk of disease, and replaces the use of traditional antibiotics.
