AI Technical Summary

Technical Problem

In existing technologies, the imbalance of gut microbiota in marine fish leads to a high incidence of intestinal diseases. The use of traditional antibiotics leads to increased drug resistance and disrupts the ecological balance. Existing microecological preparations have limited functions and lack the synergistic regulatory effects of traditional Chinese medicine extracts, making it difficult to effectively solve the intestinal health problems of marine fish.

Method used

The formulation utilizes a scientific combination of traditional Chinese medicine extracts and a complex microbial community, including seaweed extract, Anemarrhena asphodeloides extract, and Eucommia ulmoides leaf extract, as well as Rhodopseudomonas palustris, Rhodopseudomonas marinea, and Clostridium butyricum. Through scientific formulation and the use of defatted rice bran and kelp powder as carrier materials, a complex microecological preparation is formed to enhance the intestinal function of marine fish.

Benefits of technology

It significantly improves the gut health of marine fish, enhances the intestinal barrier function, increases the abundance of beneficial bacteria, reduces the proliferation of harmful bacteria, promotes nutrient absorption, improves meat quality, reduces aquaculture costs, and enhances market competitiveness.
