Because hairtail is a deep-sea fish, the pressure in the deep sea is very high. If it is not frozen and then caught, it will explode after being caught. So everything we eat is dead and frozen.

Hairtail belongs to a migratory fish. They inhabit the middle and lower layers of water during the day and will not rise to the surface until the evening. Generally, they live in the offshore waters with a water depth of 20~40 meters. Although this is not a deep-sea fish, it has some characteristics of deep-sea fish, so it is difficult to cultivate hairtail artificially, even if it is salvaged, it will be difficult to feed. Generally, it will die directly three hours after leaving the growing environment.

Unless they are kept in a constant temperature and pressure environment, they can survive. However, if the hairtail is directly placed in this environment and transported, its cost will increase, so most people can't afford it, so the hairtail is basically salvaged directly and then frozen directly in the freezer.

Some people think that the same is true of seafood. Some people think that hairtail will become very weak after leaving the sea, and will eventually rot slowly. So fishermen put hairtail in the ice, so it can keep fresh.

Because of these habits of hairtail, there is no way to breed hairtail artificially at all, and it will freeze directly after being salvaged, so frozen hairtail is also supplied in the market.

But in fact, the meat quality of frozen hairtail is also very good to eat. The meat quality is more delicate and has fewer thorns. The most important thing is that it is rich in nutrients, and the fat is also unsaturated fatty acid, which is also beneficial to our health.

Although hairtail is rarely alive and fresh, the degree of frozen freshness can also keep a lot of beneficial substances for us. If conditions permit, we might as well eat more hairtail.
