摘要：We studied genetic diversity of Chinese sturgeon (Acipenser sinensis) samples collected before and after the damming of the Yangtze River, and a sample of individuals fiom an artificial breeding group. DNA fingerprint diversity decreased dramatically after the damming of the river, and the reintroduced sturgeon had lower genetic diversity than the wild population. The construction of the Gezhouba Reservoir on the Yangtze River is probably the most direct and important reason that led to the loss of genetic diversity in the Chinese sturgeon. The farmed individuals had low genetic diversity because this artificially bred population was produced unselectively from very few parent fish.
