Hairtail mainly depends on fishing in the ocean. Because it can't be farmed artificially at present, it belongs to wild resources.

Hairtail (1) is a deep-sea fish. Mainly living in the ocean of 200 ~ 400 meters underwater; If people are in an industrialized breeding environment, whether it is a cage, a fish pond or an industrialized greenhouse, it will not be too deep-hairtail will die suddenly because it can't adapt to a little pressure. Hairtail dies when it comes out of the water, and the technical difficulty cannot be overcome.

(2) Hairtail can't be cultured artificially, which is mainly the reproduction problem under artificial feeding. However, hairtail is a migratory fish, and many migratory fish need certain external environmental factors, such as water temperature and salinity, to stimulate gonad maturation, which is also an obstacle to the artificial reproduction of migratory fish.

(3) In addition, hairtail has another key problem that is not suitable for artificial culture, that is "self-harm within species". Hairtail often feeds on the same kind of hairtail. Generally dissecting hairtail, it will be found that 26% of the food in its stomach is its own hairtail, which is the most serious in the winter food shortage period, reaching 35%. The bigger the hairtail, the higher its predation frequency for the same kind. Therefore, hairtail has not been artificially cultured for the time being; Mainly captured from the natural environment.
