Evaluation of some microsatellite markers variability in the study of genetic structure of vendace (Coregonus albula (L.)) populations from Latvian Lakes

Vendace (Coregonus albula (L.)) is a very plastic species of freshwater whitefish which is widespread in Europe. But in Latvia this species is included into the list of specially protected fish species with limited use. We examined cross-species amplification of 14 microsatellite loci (Cocl-Lav22, Cocl-Lav23, Cisco-59, Cisco-106, Cisco-90, Cisco-126, Cisco-157, Cisco-179, Cisco-181, Cisco-183, Cisco-200, BWF1, BWF2, and C4-183) which were successfully used for genetic studies, monitoring, protection and management of different Coregonus species. Five microsatellite markers (BWF1, Cisco-90, Cisco-126, Cisco-157, Cisco-200) had a good representation in populations of vendace from five Latvian lakes (Sventes, Raznas, Nirzas, Dridzas, Stirnu) and were used for genetic analysis of these populations. It was shown that these 5 microsatellite loci were polymorphic and could differ among the investigated populations. The mean number of alleles per locus (from 4.4 to 6.2), the observed (from 0.53 to 0.70) and expected (from 0.49 to 0.70) heterozygosity, population structure (FST and RST) and gene flow (Nm) were also analysed in Latvian vendace populations.
