Genetic diversity and reproductive success of a wild population of Chinese sturgeon ( Acipenser sinensis) from the Yangtze River inferred from juveniles born in 2014.

ABSTRACT: The Chinese sturgeon ( Acipenser sinensis Gray, 1835) is a large anadromous fish species, which is under considerable threat due to dramatic declines in population numbers. In the current study, population genetic diversity and individual reproductive success were assessed using nuclear microsatellite markers (simple sequence repeat, SSR) and complete mitochondrial (mtDNA) genome analysis of juveniles born in 2014. Results showed the existence of size polymorphism in the mtDNA genome of Chinese sturgeon, which was caused by a repeat motif. Population genetic diversity was high based on both SSR ( Ho: 0.728±0.211; He: 0.779±0.122) and mtDNA genome analyses ( H: 0.876±0.0035; Pi: 0.0011±0.0010).
