The shrimp is a well-known and rare aquatic product for consumers in China, such as China, China and the like because of tender meat, delicious taste and rich nutrition. Since the last 90 s, the culture range of the penaeus japonicus in China is gradually expanded from south to north, and the penaeus japonicus culture method has been developed into one of the leading varieties for culturing the penaeus japonicus in various regions in the country in recent years. Due to the relative lag of the breeding method, the yield of the marsupenaeus japonicus in China is generally low, and the demand of the live shrimps in the market is larger and larger, so the price is continuously good.
