1, Hairtail is a deep-sea fish, which is characterized by high pressure resistance. Hairtail generally lives within 30-200 meters underwater. Because of the different pressures in deep sea and qianhai, when fishermen salvage hairtail, the water pressure will change from high to low, and hairtail will die because of the change of water pressure, so this is why we can hardly see live hairtail. If it is cultivated artificially, it will hardly meet the living conditions of hairtail. In fact, not only do we see live hairtail in the market, but we don't see hairtail in the aquarium. It is because hairtail will die once it leaves the deep sea, and our current technology can't guarantee that hairtail will still survive after leaving the deep sea.

2. Hairtail is a migratory fish. The characteristic of migratory fish is that it will migrate thousands of miles according to the season and water temperature. Hairtail carries out reproductive migration and wintering migration every year according to the season and water temperature. In addition, hairtail likes to pair up in groups. Generally, there will be thousands of hairtail when migrating, and each migration will form a fishing season. Therefore, if hairtail is cultivated artificially, it is necessary to provide an environment for hairtail migration, which is basically impossible.

3, hairtail is usually more than ten yuan a catty, and it may only cost eight or nine yuan to buy at the seaside. The reason why the price of wild hairtail is not high is related to the output of hairtail. The annual output of hairtail is more than 800,000 tons, so the price of hairtail in the market is not high, because the wild hairtail has met the needs of consumers, and it is a bit uneconomical to spend a lot of energy and money on artificial breeding of hairtail. The reason why many people don't know whether hairtail can be cultured is related to the two kinds of hairtail we usually eat. China has two major hairtail producing areas, hairtail in the East China Sea and hairtail in the South China Sea. Hairtail in the South China Sea is wide, with yellow eyes and thick meat. Hairtail in the East China Sea is relatively narrow and delicate in meat quality. Although they are both hairtail, the taste of them is very different. Many people think that they are wild hairtail after buying hairtail from South China Sea.

4. In fact, we can't breed hairtail artificially at present. Besides our current breeding technology can't meet the survival of hairtail, the most important point is that it has something to do with the price of hairtail. The reason why people choose artificial breeding is to maximize the benefits. At present, the price of wild hairtail itself is not high. If it is cultivated artificially, the price will be even lower. It takes a lot of time and energy to cultivate hairtail, which is not worth the candle.
