Historical reasons for Penaeus vannamei entering aquaculture in China
In 1980s, China's shrimp farming industry developed rapidly and became an important part of China's coastal economy. However, in the early 1990s, shrimp virus began to spread all over the country, and no countermeasures could be found in a short time. It dealt a heavy blow to the shrimp farming industry at that time.
While studying the prevention methods of shrimp virus, researchers began to explore new alternative varieties. Since 1988, China has carried out the introduction, adaptive breeding and large-scale promotion of Penaeus vannamei; First, a new species of Penaeus vannamei was introduced by the Institute of Oceanography of China Academy of Sciences. Since 2000, the scale of Penaeus vannamei culture has expanded year by year.
