Abstract

Varicorhinus alticorpus (Cyprinidae) is an endangered freshwater fish with a scattered distribution in the southern and eastern regions of Taiwan. We described the development of nine polymorphic microsatellite loci in V. alticorpus for genetic studies. These new markers were tested in 20 individuals of the rare species. The number of alleles ranged from 4 to 13. Expected (H E) and observed (HO) heterozygosities ranged from 0.692 to 0.892 (averaged at 0.821) and from 0.000 to 0.350 (averaged at 0.088), respectively. All loci are significantly deviated from Hardy-Weinberg expectations due to the heterozygote deficiency. This suite of highly polymorphic microsatellites provides the first chance to undertake a conservation program for this species in Taiwan. It is essential to evaluate its genetic diversity and the fine-scale population structure.
