The reason why hairtail has become a popular seafood is mainly because of the following points: hairtail itself has high yield, and hairtail is just like the four major fishes among freshwater fish, with a large number.

The transportation cost of hairtail is low, because hairtail is not easy to survive, so it is transported frozen.

There are few intermediate links in the transportation of hairtail. Since the hairtail is frozen, it is sent directly from the port to various places, so there are not too many intermediate links to increase the transportation cost.
