Abstract
Bream (Abramis brama orientalis) is one of the most commercially valuable fish in the Caspian Sea. The aim of this study was to compare levels of genetic polymorphism between wild and farmed Bream populations using seven microsatellite loci. Genetic diversity was investigated by studying samples collected from two regions; Chaboksar and the Artificial Propagation Center of Guilan province. Allele frequency was found to have declined in wild and cultured fish due to inbreeding and genetic drift. Significant population differentiation (Fst) was observed between wild and farmed populations, which could be explained by the low number of alleles in two populations. Significant deviations from the Hardy-Weinberg equilibrium were found at more loci. Beyond the null alleles' hypothesis, heterozygote deficiency may have arisen due to inbreeding. Both populations showed lowest genetic diversity according to the number of alleles and genotypes per each locus. This approach was carried out for the first time and could provide information regarding the genetic variability of farmed and wild abramis brama fish using microsatellite markers. Results could be used for the management and conservation of artificial Bream propagation programs.
