POPULATION GENETIC ANALYSIS OF ATLANTIC BONITO Sarda sarda (BLOCH, 1793) USING SEQUENCE ANALYSIS OF MTDNA D-LOOP REGION

WOS: 000366880400011
In this study mitochondrial DNA D-loop gene sequencing was used to investigate genetic structure of 11 Atlantic bonito Sarda sarda populations from the Black Sea, Marmara, Aegean, Mediterranean Seas and Adriatic Sea. The total sequence length, variable sites and parsimony informative sites were 868 bp, 12 bp and 7 bp from 222 individuals, respectively. The nucleotide frequencies were 32.55% A, 31.32% T, 14.44% C, and 21.68% G. The total number of haplotypes was 19, and the highest number of different haplotypes was observed in the nortestem Mediterranean (the Iskenderun Bay) sample, and the lowest was observed in the Bulgarian sample. Low genetic diversity was observed within populations, and the mean genetic diversity within populations and the mean genetic divergence between populations were 0.0009 and 0.0013, respectively. In the statistical analysis, S. sarda was divided into three genetically different populations (P
