'Fish dads' breed rare species to replenish Yangtze

The institute began captive breeding of the species in the 1970s. After years of scientific research and practice, it has become a national original breeding base.

For now, the institute has reserved more than 3,000 Yangtze sturgeon parent fish. That species is under first-class State protection in China. It is also concerned with the protection of other species — for example, the Yanyuan carp, Onychostoma angustistomata and Percocypris pingi.
