Following the outbreak of epidemic virus disease in shrimp farming in China in 1993, China’s shrimp industry suffered heavy losses. After that, P. vannamei was introduced into our country and rapidly developed. You make up for the economic losses caused by diseases caused by shrimp cultivation in our country.

How to deal with and solve the current
