1. During the fermentation process, the strain generates rich nutrients and bioactive components, improving palatability and significantly increasing food intake. Promote the digestion and absorption of feed, improve the utilization rate of feed, and shorten the breeding cycle.

2. It has strong colonization ability and can inhibit harmful microorganisms in the intestinal tract through competition or secretion of bacteriocins, etc., maintaining the balance of the intestinal microecology.

3. Metabolic products such as lactic acid and other organic acids contribute to the absorption of calcium, iron and vitamins. Calcium lactate formed under certain conditions can promote the molting and growth of crustaceans.

4. It can regulate the pH value of the water body, decompose organic matter such as leftover feed and feces, optimize the bottom quality and water quality of the pond. Regular use can inhibit the reproduction of harmful algae such as cyanobacteria and dinoflaglae.
