Abstract

Based on ten microsatellite loci of nuclear DNA, we have analyzed for the first time the genetic variability of European perch Perca fluviatilis (L., 1758) from four reservoirs of the Sebezhsky National Park, Sebezhsky district, Pskov oblast, which are part of a single lake–river system. The average estimates of the allelic diversity of microsatellite loci and the observed heterozygosity were A = 8.87 and HE = 0.694 and did not significantly differ between the studied localities. The overall genetic differentiation of the perch was θ = 0.002, 95% CI (–0.0007; 0.005) and was statistically insignificant. The population-genetic structure based on the studied multilocus genotypes has not been found by the Bayesian analysis method. The resulting data indicate a high level of gene flow in the perch throughout the studied water area and suggest the presence of a genetically unified panmix population in the system of Sebezh lakes and rivers.
