Özet:

In Turkish marine waters, pufferfish belongs to Tetraondontidae family are represented with 8 species, Lagocephalus lagocephalus, L. sceleratus, L. spadiceus, L. suezensis, L. guentheri, Sphoeroides pachygaster, Torquigener flavimaculosus and Tylerius spinosissimus. DNA barcoding can be useful in the assessment of cryptic or morphologically similar species of identification which is widespread in marine environment. DNA barcode identification of the eight puffer species of the Tetraodontidae family in Turkish marine waters were examined by using mtDNA sequencing of the amplified partial mitochondrial cytochrome c oxidase I (COI) gene. COI contained 189 variable and 337 conservative nucleotides of which 183 were parsimony informative over 526 bp. Mean genetic diversity all species was found 0.18164. The highest and lowest nucleotide divergence was observed L.spadiceus (0.0022) and between L. sceleratus, L. suezensis, L. lagocephalus, L. guentheri and S. pachygaster (0.0000) respectively. The number of detected different haplotypes were 10 out of 23 sequences, and haplotype diversity was found to be 1.000.
