Genetic diversity of Abramis brama (Berg, 1905) in Chamkhale and Bandaranzali coast using Microsatellite Markers

Abramis brama orientalis is one of the osteichties fishes of Caspian sea. 30 samples from each region(Bandaranzali and Chamkhale) were collected to investigate the genetic diversity and population structure of Abramis brama. In this study, all of seven microsatellite loci studied (Rser10, Ic654, MFW7 , MFW26 , Bl2 -114, Bl1 -153, M4) showed polymorphism. No observed any obvious genetic destinguish in terms of Fst , Rst and Analysis of Molecular Variance. The average number of allele’s levels in the population accounted for 10.5, The expected and observed heterozygosity mean were 0.820 and 0.615, respectively. Approximately all of loci showed deviation from Hardy-Weinberg equilibrium. The genetic similarity and distance between the two populations were 0.316 and 0.684, respectively. According to the analysis, it seems that Abramis brama hasn᾽t a desirable genetic diversity in the investigated regions.
