Problems solved by technology

However, the use of antibiotics can easily lead to the development of drug resistance of diseased microorganisms, leading to the failure of antibiotics; in addition, the use of antibiotics can easily lead to metamorphosis of larvae and drug residues, resulting in slow growth of seedlings and low yields in the later breeding process, which seriously affects the breeding income of farmers

Furthermore, the improvement of water quality was neglected in the process of raising seedlings, resulting in the inability to substantially improve the survival rate of seedlings

[0003] Judging from the existing patents and papers, there is no report on Chinese herbal medicine additives for controlling oyster seed diseases and increasing seed production. Body, improve immunity and other advantages, in the process of preventing and treating aquatic animal diseases, in addition to both medicinal and nutritional properties, it also has the effect of improving the production performance and feed utilization rate of aquatic animals, so more and more attention has been paid to it, and its application is becoming more and more extensive
