? Hairtail is a common seafood in China. It lives in seawater. It is a marine fish and an important edible fish species. Marine fish is a very large category, it can also be more detailed division, can start from different standards can be divided into specific sub-categories are different. Deep-sea fish and shallow-sea fish are classified according to the depth of the sea they live in. These two kinds of fish live in different depths of the sea. Hairtail belongs to the shallow sea fish, not the deep sea fish.
Specifically, the distribution depth of hairtail is concentrated between 60-100 meters, generally speaking, it is relatively shallow, that is, shallow sea area. However, the hairtail sometimes moves to slightly deeper waters, for example, when winter comes, they will go to slightly deeper waters in groups to spend the winter, and then return to shallow waters when the temperature rises. But even so, their distribution depth is only about 100 meters, not particularly deep. To meet the requirements of deep-sea fish, it should be distributed at least hundreds of meters deep, or even thousands of meters deep, and hairtail obviously does not meet the requirements.
? As mentioned above, hairtail itself is a marine fish, and has been living in the ocean, and has fully adapted to the environment in the long-term life process. Therefore, the breeding of hairtail is more troublesome, more difficult than the breeding of freshwater fish, because they have higher requirements for the water environment, and the cost of investment is relatively large. However, due to the large demand for hairtail in the market, it is more popular, so in real life, there are also some hairtail cultured artificially, but overall, the number is not particularly large, more or fishing, the cost of fishing is much lower than that of artificial breeding.
