چكيده لاتين :
Stocks variation of 10 economical species of fish in the southern coast of the Caspian Sea including Cyprinus carpio, Rutilus kutum, Neogobious gorlap, Neogobious caspius, Sander lucioperca, Clupeonella cultiventris, Liza aurata, Rutilus frissi, Vimba vimb and Esox lucius were assessed by reviewing related microsatellite studies. For this purpose, the heterozygosity and allelic frequency of these species compared to those reported by DeWoody and Avis. The heterozygosity and allelic frequency in Rutilus kutum and Vimba vimba was respectively higher and lower than those reported for anadramus fish (h = 0.68, α = 11.3). In Cyprinus carpio and Rutilus rutilus , the heterozygosity and allelic frequency was near to fresh water fish (h = 0.58, α = 7.5). Both studied indices in Liza auratus were reported lower than reported in marine fish (h = 0.79, α = 20.6) and within those reported in anadramous and fresh water for Neogobious and Clupeonella cultriventris . The results showed that in most studied species of the Caspian Sea,there are somesymptoms of the genetic diversity reduction and genetic bottleneck
