Abstract
In the present study, we developed 16 polymorphic microsatellite loci in Rhinogobio ventralis, an endemic cyprinid fish in the upper reaches of the Yangtze River. The polymorphism of each locus was assessed in 32 individuals collected from Jiangjin section of the Yangtze River. A total of 126 alleles were detected and the number of alleles per locus ranged from 2 to 16. The observed and expected heterozygosities ranged from 0.161 to 0.968 and from 0.154 to 0.928, respectively. Two loci significantly deviated from Hardy–Weinberg equilibrium. No significant linkage disequilibrium was found between pairs of loci. These polymorphic microsatellites will be useful tools in the study of genetic diversity and population structure of R. ventralis.
