More than 200,000 fully artificially bred Chinese sturgeons from the Three Gorges Group successfully emerged

　　China News Agency, Yichang, September 27th (Guo Xiaoying, Sun Yufang, Chen Xueqian) According to the news of the Three Gorges Group on the evening of the 26th, more than 200,000 artificially bred Chinese sturgeons successfully emerged at the China Sturgeon Research Institute of the Three Gorges Group. This is the full artificial breeding of the institute in 2022. The first offspring of the second generation Chinese sturgeon emerged.

　　This batch of Chinese sturgeon seedlings emerged around 20 days ago and are currently being temporarily raised in the cultivation pool of the seedling cultivation workshop of the Chinese Sturgeon Research Institute.

The newly hatched seedlings also have yolk sacs, which look like moving bean sprouts, moving up and down in the water, which the researchers call "splashes".

　　"'Shuihua' is relatively fragile, and has higher requirements for water temperature and water quality." Zhang Jianming, a senior engineer at the Chinese Sturgeon Research Institute, said that this year, the institute introduced the recirculating aquaculture model into the early seedling process of Chinese sturgeon for the first time. Accurately control water quality and water temperature to provide a high-quality early living environment for Chinese sturgeon seedlings.

　　In addition to artificial breeding of this batch of Chinese sturgeon seedlings, the Chinese Sturgeon Research Institute will continue to carry out multiple batches of breeding work this year.

　　Combined with this breeding work, the Chinese Sturgeon Research Institute also simultaneously launched the Chinese sturgeon gynogenesis and frozen semen experiments, continued to carry out research on Chinese sturgeon species protection technology, and provided stronger technical support for Chinese sturgeon protection.

　　Chinese sturgeon is one of the oldest vertebrates on earth, with a history of 140 million years. It is known as "living fish fossil" and "water giant panda". It has important scientific research and ecological value.

In recent years, the wild population of Chinese sturgeon has continued to decline. In 1988, it was listed as a national first-class wild animal, and in 2010, it was listed as a critically endangered species by the International Union for Conservation of Nature (IUCN).

　　After more than 30 years of artificial breeding and technical research, the Chinese Sturgeon Research Institute of the Three Gorges Group has established a complete artificial population echelon of Chinese sturgeon, carried out research on the protection of the whole life cycle such as broodstock breeding and induced reproduction, and mastered technologies such as full artificial breeding of Chinese sturgeon.
