Legally certified sturgeon fisheries require population protection and conservation methods, including DNA tests to identify the source of valuable sturgeon roe. However, the available genetic data are insufficient to distinguish between different sturgeon populations, and are even unable to distinguish between some species. We performed high‐throughput single‐nucleotide polymorphism ( SNP )‐genotyping analysis on different populations of R ussian ( A cipenser gueldenstaedtii ), P ersian ( A . persicus ), and S iberian ( A . baerii ) sturgeon species from the C aspian S ea region ( V olga and U ral R ivers), the A zov S ea, and two S iberian rivers. We found that R ussian sturgeons from the V olga and U ral R ivers were essentially indistinguishable, but they differed from R ussian sturgeons in the A zov S ea, and from P ersian and S iberian sturgeons. We identified eight SNP s that were sufficient to distinguish these sturgeon populations with 80% confidence, and allowed the development of markers to distinguish sturgeon species. Finally, on the basis of our SNP data, we propose that the A . baerii ‐like mitochondrial DNA found in some R ussian sturgeons from the C aspian S ea arose via an introgression event during the P leistocene glaciation.
