Problems solved by technology

[0004] Most of the existing grass carp feeds have problems such as unbalanced nutrition, excessive addition of hormone drugs, and high content of heavy metals, which cause grass carp to be prone to various diseases and drug residues, which seriously affect the breeding efficiency of grass carp. Therefore, in order to improve the breeding efficiency , improve the quality and quality of fish products, change the feed formula, ensure balanced nutrition, improve the disease resistance and antibacterial ability of grass carp, and increase the selenium content of grass carp meat to improve its function. Modern fish farming has very good social and economic value.
