It is said that hairtail originated from a fish that looks like a knife. Most of the hairtail we eat are silver hairtail and black hairtail, but the ones we caught by fishing are silver hairtail. You can think of it as black hairtail fish caught with a net. It is often divided into Jeju silver hairtail and Mokpo black hairtail. As its name suggests, silver hairtail is characterized by shiny silver scales. Black hairtail fish have a little bit of a dark color. Silver hairtail is hard meat. Black hairtail fish are usually caught in the distant sea, and the seeds are thick and oily, so it has a soft and savory taste. Galchi is a protein food that contains essential amino acids such as razin, phenin alini, and methionine, and is said to be especially good for growing children. The taste is delicious, but I think it is a fish that is loved more because it can be eaten in various menus such as grilled, stew, soup, and stew.
