Baby fish is wearing a "gold collar" to visit the market.

On August 4, the author saw at the Jishui giant salamander breeding cooperative breeding base in Jiyuan City, Henan Province, that technicians were wearing logo plates for several baby fish to be sold to Beijing.

This is an identity card with a smart chip implanted, because it is right around the doll's neck, and Han Dong, the head of the cooperative, vividly calls it a "gold collar." "with it, farmed baby fish can enter the market without hindrance, and we can rest assured to raise and sell them!" Han Dong said happily.

The author took out his mobile phone, turned on the "scan" function, and scanned the QR code on the circular sign, and the information about the weight, origin, identification time and unit of the giant salamander was clear at a glance.

The fishery administration and technical personnel who accompanied the interview told the author that in order to avoid the repeated use of signs so that they could be traced back in case of problems, all signs could not be taken off once they were put on. Every doll fish to be sold should wear such a sign around its neck, which is the unique "ID card" of every doll fish.

In 2009, under the guidance of the fishery administration department, the Jishui giant salamander farming cooperative, the first baby fish farming professional cooperative in Jiyuan City, was established. On the one hand, the person in charge of the cooperative, Han Taiguo, and others went to Hanzhong and other places in Shaanxi to introduce baby fish seedlings, on the other hand, they hired high-paid technical personnel to take advantage of the characteristics of high altitude and large temperature difference in Wangwu mountain area to imitate the living environment of baby fish. Actively explore doll fish imitation ecological reproduction technology.

In 2013, the cooperative succeeded in ecological reproduction of doll fish imitation, achieving a breakthrough of zero ecological reproduction in Henan Province. Over the past three years, the survival rate of baby fish seedlings has increased from less than 50% at the beginning to 95%. So far, Jiyuan City has 5 professional cooperatives for baby fish farming, with more than 150 peasant households and about 180000 baby fish farmed.

With the mass reproduction of the second and third generations, eating baby fish has gradually entered the homes of ordinary people, and some farmers have a considerable income as a result.

"when it comes to eating baby fish a few years ago, most people would find it inconceivable. Now, my restaurant can 'eat' thousands of baby fish every year. " Jia Jianping, who runs a characteristic hotel in Fanzhuang Village, Jiyuan City, said. Jia Jianping is also in charge of the Sturgeon and Salamander breeding Cooperative in Jiyuan City. Since the establishment of the cooperative in 2011, the scale of breeding has gradually expanded. At present, there are 60, 000 baby fish and 50, 000 Sturgeon. In the next two years, the number of baby fish and Sturgeon will reach 100000 respectively.

With the increasing maturity of aquaculture technology, the baby fish market has developed from selling seedlings to edible commodity baby fish. Since last year, on the one hand, Jia Jianping has continued to go to Guangzhou, Beijing and other places to contact and sell merchandise baby fish, on the other hand, he runs his own restaurant and manages special catering of baby fish. Many people in Zhengzhou, Luoyang and Jiaozuo came to taste it. Up to now, two franchise stores in Luoyang Xin'an and Longmen have been opened, and a restaurant in Gongyi has also sent people to learn to cook. "in the next step, we will also develop baby fish products such as' giant salamander pot'." Jia Jianping said confidently.

The success of artificial breeding in turn promotes the conservation of wild baby fish resources. Wang Qiang and Wang Dongqiang brothers from Linshan Village, Wangwu Town, Jiyuan City, told me that in the past two years, they could hear the cry of wild baby fish every night. "it's as if our child has been lost for many years, and now he's back." Wang Qiang, 42, said it made him feel like he was back in his childhood.
