Chinese sturgeon is an ancient and rare fish unique to China. It has been multiplying on the earth for 140 million years. It is known as a “living fossil†and is a state-level animal protection animal. According to China Yangtze River Research Institute of China Three Gorges Corporation, at 18:40 on November 1, the institute successfully implemented artificial propagation and oxytocin production for a group of “child generation†Chinese sturgeon at the research base of the Three Gorges dam area. 150,000 pieces, the first fry were broken at 10 am on November 5th. As of 8 o'clock on November 6, a total of 12,000 Chinese sturgeons have emerged successfully, and the total number of seedlings to be raised is expected to reach 80,000 to 100,000.
This is the fifth time since the Chinese sturgeon research institute broke through the artificial breeding technology of Chinese sturgeon for the first time in 2009. It achieved full artificial reproduction for the fifth time, and the fertility, fertilization rate, and good egg rate of the broodstock that participated in the breeding reached the level of wild sturgeon. In addition, the broodstock that participated in the breeding are all second maturing, which means that the Chinese sturgeon group that was long-termly stocked by the Chinese sturgeon research institute can repeatedly participate in breeding until the end of the breeding cycle.
According to Gao Yong, deputy director of the Institute, the broodstock rehabilitation and re-maturation is the “last step†of full-scale artificial reproduction technology. The breakthrough of this technology marks the completion of the artificial propagation technology system of Chinese sturgeon, and it also marks the technical solution of humans. Chinese sturgeon species retention problem.
