1, high yield: the output of hairtail is the highest among marine fish, and it is also called the four seas fresh in China with large yellow croaker, small yellow croaker and squid, with an annual output of more than one million tons, so the price of hairtail will be cheaper due to market supply and demand factors.

2. Low transportation cost: hairtail will die within a few hours after going out to sea, and can only be transported by freezing. Compared with other live fish transportation, it reduces the cost and naturally reduces the price.

3. Few intermediate links: In some large supermarkets, the price of hairtail is very cheap, because some large supermarkets purchase goods directly from the port, reducing intermediate links. The less the loss, the lower the cost, and the cheaper the hairtail consumers buy.
