“…This differentiation was shown in previous studies with morphology, mtDNA and STR markers of the Russian sturgeon from the Black Sea-Azov and the Caspian basins ( Timoshkina et al , 2009). The present study has now confirmed these results using the AFLP method.…”

“…It was shown that a ‘baerii-like’ mitotype of A. gueldenstaedtii is similar, but not identical, to mitochondrial DNA of A. baerii ( Muge et al , 2008). In total, 2% of Russian sturgeons in the Azov Sea also have a ‘baerii-like’ mitotype ( Timoshkina et al , 2009), whereas this has not been found in Persian sturgeons ( Muge et al , 2008). It is assumed that the ‘baerii-like’ mitochondrial DNA found in some Russian sturgeons from the Caspian Sea is a result of an introgression event during the Pleistocene glaciation ( Muge et al , 2008; Rastorguev et al , 2013).…”

Russian ( ), Persian () and Siberian ( ) sturgeons are closely related 'Ponto-Caspian' species. Investigation of their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, 'baerii-like' mitotypes were found in the Caspian Sea among 35% of Russian sturgeon specimens, but were not found in Persian sturgeons. This confirms genetic isolation of the Persian sturgeon from the Russian sturgeon in the Caspian Sea. However, in order to clarify the relationships of these species it is necessary to analyze nuclear DNA markers. The amplified fragment length polymorphism (method) allows estimating interpopulation and interspecific genetic distances using nuclear DNA markers. In the present study, four samples were compared: Persian sturgeons from the South Caspian Sea, Russian sturgeons from the Caspian Sea and the Sea of Azov, and Siberian sturgeons from the Ob' River, which are close to these two species, but are also clearly morphologically and genetically distinct from them. For the AFLP method, eight pairs of selective primers were used. The analysis revealed that the Siberian sturgeon has formed a separate branch from the overall Persian-Russian sturgeons cluster, which was an expected result. In addition, the results showed that the Caspian Russian sturgeon is closer to the Persian sturgeon from the Caspian Sea than to the Russian Sturgeon from the Sea of Azov. The present DNA marker data confirm that despite the genetic isolation of the Persian sturgeon from the Russian sturgeon in the Caspian Sea, the Persian sturgeon is a young species.

“…It was previously shown that the two , four and eight gene manifestation of the different loci is possi ble in the Russian sturgeon [3,7,[34][35][36][37][38][39]. The sugges tions about the two and four gene encoding of the studied system of proteins were rejected by us because of the obvious mismatch of the expected in accor dance with this hypotheses' distribution of bands on proteinograms and the distribution observed in reality.…”

“…However, there are not yet enough available data to perform detailed compar ative studies. It is only shown that the Caspian popula tion of Russian sturgeon has the greatest allelic diver sity at all microsatellite loci as compared with both the Azov and the Black Sea populations of this species and the Siberian sturgeon [3][4][5][6][7][8][9].…”

This study investigates muscle proteins in Russian (Acipenser gueldensiaedtii Brandt), Siberian (Acipenser baerii Brandt), and Amur (Acipenser schrenckii Brandt) sturgeons using the method of polyacryl amide gel electrophoresis. A group of fractions, which is presumably the product of a polyallelic duplicated MY 1* locus, is recorded among the general pool of proteins. Data from densitometric analysis makes it pos sible to put forward a hypothesis about an eight gene determination of this system of proteins. The highest heterogeneity and polymorphism was revealed in the Russian sturgeon. Analysis of the genotype distribution in samples of the studied species allowed us to make an assumption that the genetic structure of spawning sturgeon stocks is significantly metamorphosed under the influence of anthropogenic and natural factors.

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 Russian (Acipenser gueldenstaedtii), Persian (A. persicus), and Siberian (A. baerii) sturgeon species from the Caspian Sea region (Volga and Ural Rivers), the Azov Sea, and two Siberian rivers. We found that Russian sturgeons from the Volga and Ural Rivers were essentially indistinguishable, but they differed from Russian sturgeons in the Azov Sea, and from Persian and Siberian sturgeons. We identified eight SNPs 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 Russian sturgeons from the Caspian Sea arose via an introgression event during the Pleistocene glaciation.
