[0002] With the continuous improvement of consumers' preference for live aquatic products, the market demand is constantly expanding. According to relevant surveys, the domestic consumption of live aquatic products has been increasing year by year, and the market demand potential is huge. In terms of market competition, due to the characteristics of high freshness requirements and great transportation difficulty of live aquatic products, the market competition is mainly concentrated in coastal areas and large inland cities. On the one hand, the large quantity of seafood produced in the origin cannot be transported over long distances and can only be digested nearby or frozen. On the other hand, the live seafood market in the inland is in short supply and the price is high. At present, long-distance transportation mainly relies on air transportation, which has high costs and limited transport volume, restricting the consumption of ordinary people. With the improvement of people's living standards, the demand for live seafood with better taste is increasing.
