Genetic relationships among 96 specimens of ship sturgeon, Acipenser nudiventris, collected from six locations along the Iranian coastline as well as 8 specimens from northern population (Ural River) were analysed by the restricted maximum likelihood method, as well as two distance analysis method (Neiיs and Cavalli-Sforzaיs distance) of gene frequencies. We have used four SSR makers that produced three polymorphic and two monomorphic loci. Overall results showed that Iranian coastline samples form a monophyletic group (clade) which was different from the northern (Ural) samples. Iranian coastline samples are divided into two groups (clades): Anzali-Kiashahr clade and Sefidrud-Babolsar-Noushahr-Gorgan clade. Bootstrapping test showed monophyleticity of Sefidrud, Babolsar, Noushahr, Gorgan with high (Bootstrap support=93) and Anzali-Kiashahr with middle (Bootstrap support=65) confirmation. Topology of reconstructed trees was in correspondence with geographical distributions of samples.
