A few days ago, the author learned from the Fujian Academy of Agricultural Sciences that China's fish oral vaccine key technology has achieved breakthroughs, and its industrial prospects are broad, which will also bring about the speed of healthy aquaculture.

Recently, the expert group on marine and aquatic diseases from the National Aquatic Animal Pathogen Database and Guangdong, Shanghai and Fujian believes that it has broken through the key technologies of China's fish oral vaccine industrialization, which will transform and upgrade the sea freshwater aquaculture industry and reduce antibacterial chemicals. Use, reduce drug residues, improve food safety, increase farmers' income, and open up broad prospects.

Since 2004, the Institute of Biological Sciences of Fujian Academy of Agricultural Sciences has been dedicated to the innovative exploration of fish clinical medicine, and has created a process for the preparation of vaccines for fish immune stimulating compounds, and obtained three national invention patents.

It is understood that fish immunization usually uses injection, bath and oral inoculation. However, injection has problems that are difficult to operate, time-consuming and labor-intensive, and bath immunization is suitable for the fry stocking stage. Oral immunization is simple and inexpensive. It can overcome the drug resistance caused by antibacterial drugs and drug residues in fish, and help food safety.

The research and application of oral and freshwater fish oral vaccines in China is in its infancy. The breakthrough and promotion of key technologies for fish oral vaccine industrialization will transform and upgrade the healthy aquaculture industry, reduce the use of chemical agents, promote the development of related industries, and increase farmers' income. Open up broad prospects.
