Wild freshwater shrimps in rivers and lakes have the highest nutrition and sweet taste. lactagogue has the best nourishing and aphrodisiac effect, and few wild freshwater shrimps are sold in key markets, so the price is the most expensive. Now large lakes with better water quality in the central and western parts of Honghu Lake, Dongting Lake and Chaohu Lake can be supplied on a small scale. Metapenaeus ensis has a good taste, a big meat is delicate, the price of seawater fishing is high, and the price of artificial breeding is not good, with a fresh 40%; According to the size and specification of prawns, the price of prawns is as high as 100 yuan per catty, which is cheaper than that of metapenaeus ensis, a shrimp producer in rivers, lakes and Qinghai. White shrimp is the cheapest 20-30 a catty. The above is the price situation of live shrimp. The price difference of dead shrimp is large depending on the freshness. Fresh dead shrimp can be eaten, but it is not as good as the nutrition and taste of live shrimp!
