The genetic polymorphism of ten sturgeon species that inhabit the territory of the Russian Federation (Russian sturgeon, Siberian sturgeon, Amur sturgeon, Sakhalin sturgeon, Persian sturgeon, ship sturgeon, sterlet, stellate sturgeon, beluga, and kaluga) was examined at five microsatellite loci (Afug41, Afug51, An20, AoxD161, AoxD165) (in total, 3821 individuals). The examined loci were successfully amplified with the same primer set in all species tested and demonstrated a high level of variation. Alleles specific to different species have been identified, which allows them to be used to identify species of sturgeon and their food products. In addition, the possibility of identifying hybrid forms was demonstrated. The assignment test performed in the STRUCTURE software program showed a high probability of correctly assigning each individual to its species based on genotyping with five microsatellite loci examined (96–98%, on average). However, for Russian and Persian sturgeon, the rate of proper species assignment was considerably lower (75 and 84%, respectively).
