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 (L.) in the Turkish Seas was determined using the partial sequence of mitochondrial DNA cytochrome b gene (997 bp). Localities where annular seabream samples collected were as follows: the eastern Mediterranean Sea (Adana), the western Mediterranean Sea (Antalya), the Aegean Sea (İzmir), the Marmara Sea (Canakkale and İstanbul), Mid-Black Sea (Sinop) and the Eastern Black Sea (Rize). The population genetic structure was estimated through pairwise F ST , analysis of molecular variance and phylogenetic analyses (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 (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.Keywords : Annular seabream, cytochrome b, genetic structure
