Population genetic Structure of Otolithes ruber in Persain Gulf (Iranain coastal waters)

Otolithes ruber is a commercially important species in Persian Gulf. We estimated the genetic diversity and population structure among six populations of O. ruber from Iranain coastal waters(Khormosa, Hendijan, Genaveh, Boushhr, Dayer and Asaloyeh) using amplified fragment length polymorphism (AFLP) technology. A total of 345 bands were amplified for 80 individuals by 7 pair selective primers (+3), 37.27% of which were polymorphic bands. Minimum and maximum polymorphic band percent obtained from EAA/MCAT(39) and EACA/MCAG(25%) respectively. Average of genetic diversity and Shannon index were calculated 0.28 and 0.5 respectively. Boushhr showed the highest genetic diversity (0.33) and Shannon genetic diversity (0.5). Pairwise FST values were between 0.022 to 0.23. Significant genealogical branches or clusters corresponding to sampling localities were detected by UPGMA tree. The results of AMOVA analysis and pairwise FST values showed genetic divergence among different geographic populations. Pairwise Fst and UPGMA tree revealed significant genetic differentiation among Khormosa, Boushhr and dayer. But genetic differentiation wasn’t height among population.
