1. Different distribution ranges
Chinese shrimp is distributed in the Bohai Sea of ??my country; vannamei is distributed in the tropical waters of the Pacific coast of the western United States, from the Gulf of Mexico to central Peru. The waters near Ecuador are more concentrated.
2. Different morphological characteristics
The female adult of Penaeus chinensis is generally 18-23cm in length, and the male adult is 13-17cm. The body shape is flat on the sides, the carapace is thin, and the surface is smooth. Generally, female shrimps are larger than male shrimps;
The adults of Penaeus vannamei can be up to 24cm in length, have thin carapace, normal body color is light blue-gray, and have no markings on the whole body. The distinctive feature is that the legs are often chalky.
3. The origin of the name is different
The origin of the name of Chinese shrimp is that when it is sold in the market in northern my country, it is priced in units of "a pair"; Vannamei shrimp is priced in units of "a pair". It gets its name from its resemblance to the Chinese prawn and its often chalky legs.

The historical reasons why Penaeus vannamei entered my country’s aquaculture industry
In the 1980s, my country’s shrimp farming industry developed rapidly, and coastal areas of my country important part of the economy. However, by the early 1990s, the shrimp virus began to spread across the country, and no countermeasures could be found in a short period of time. It dealt a heavy blow to the shrimp farming industry at that time.
While studying ways to prevent shrimp viruses, researchers began to explore new alternative species. Since 1988, my country has carried out the introduction, adaptive breeding and large-scale promotion of Penaeus vannamei; first, the Institute of Oceanology, Chinese Academy of Sciences introduced a new species of Penaeus vannamei. After 2000, the scale of Penaeus vannamei farming has expanded year by year.
