Abstract :Considering its importance and lack of information on its genetic structure, in this study, population genetic structure and genetic diversity of the annular seabream Diplodus annularis insert ignore into journalissuearticles values(L.); in the Turkish Seas was determined using the partial sequence of mitochondrial DNA cytochrome b gene insert ignore into journalissuearticles values(997 bp);. Localities where annular seabream samples collected were as follows: the eastern Mediterranean Sea insert ignore into journalissuearticles values(Adana);, the western Mediterranean Sea insert ignore into journalissuearticles values(Antalya);, the Aegean Sea insert ignore into journalissuearticles values(İzmir);, the Marmara Sea insert ignore into journalissuearticles values(Canakkale and İstanbul);, Mid-Black Sea insert ignore into journalissuearticles values(Sinop); and the Eastern Black Sea insert ignore into journalissuearticles values(Rize);. The population genetic structure was estimated through pairwise F ST , analysis of molecular variance and phylogenetic analyses insert ignore into journalissuearticles values(NJ, MP, ML and BI);. As a result the genetic variability was low among the population based on haplotype and nucleotide diversities of cytochrome b gene. However, phylogenetic analyses of the cyt b haplotypes showed up there are two possible genetic groups insert ignore into journalissuearticles values(the Aegean-Mediterranean and Marmara-Black Sea); suggesting that the presence of restricted migration at the Straits of Dardanelles, separating the Aegean and Marmara Seas.
