Is the yellow river swordfish farmed?

Basically, all the swordfish eaten in the market are cultured artificially. In the early 198s, the swordfish of the Yellow River estuary was only about .3 yuan/kg. Even before and after 1992, under the premise that the swordfish of the Yellow River was rare, its price was only tens of yuan/kg. In the later period, the price of authentic swordfish of the Yellow River soared all the way, but it was already valuable at that time. There was a joke among the local people in the Yellow River estuary that the swordfish of the Yangtze River was rare, but. In recent years, in order to restore the ecological environment in the lower reaches of the Yellow River, the Yellow River Water Conservancy Commission has continued to make artificial and overflow water supply to the wetland ecosystem in the Yellow River Delta, especially since 218, which has effectively promoted the natural restoration of the ecosystem in the lower reaches of the Yellow River, the estuary delta and the nearby sea areas, by increasing the water surface area of the wetland in the upper reaches of the Yellow River, raising the groundwater level, and repairing various habitats and fish migration channels in the lower reaches of the Yellow River. The reappearance of the Yellow River saury, people are excited about its return. At the same time, it will be a signal that the restoration of the natural environment of the Yellow River has achieved initial results, which will also be a "leader". With the sustainable development of the ecological environment of the Yellow River, more and more endangered or even extinct creatures will surely appear in the public's field of vision again.
