Study of genetic diversity of Sharpnose mullet Liza saliens (Risso, 1810) in the coastal regions of Mazandaran Province by microsatellite marker

Sharpnose mullet is an exotic species of Caspian Sea which was translocated from Black sea to Caspian Sea during 1930 to 1934 then colonized successfully and now it is commercial species of Caspian Sea. There are no information at molecular level about this species after 8 decade presence in Caspian Sea, therefor in order to investigation of genetic structure of Sharpnose mullet (L. saliens) in two regions, Babolsar (27 specimens) and Tonekabon (30 specimens), of Mazandaran Province was used 6 microsatellite loci. Results showed low allelic richness (Na=5) and high level of Heterozygosity (Ho=0.821). So genetic diversity of species this was very low relative to marine species. Also, genetic differentiation index between population was very low (0.032) due to natural migration and high gen flow (10.4) between these regions.
