Bluefish (Pomatomus saltatrix) is a commercially important, highly migratory
predatory fish species distributed along the coasts of Türkiye. Conservation and
sustainability of bluefish populations requires knowledge of the genetic structure of
the population, but There are no genetic studies on bluefish in Türkiye. In this study,
the population structure of Bluefish in the coastal regions of Türkiye was investigated
by sequence analysis of mitochondrial DNA gene regions (Cytochrome b and
Displacement-loop) and nuclear gene region (Rhodopsin). We tried to identify bluefish
samples collected from 14 regions in the coastal region of Türkiye by analyzing two
mtDNA gene sequences (Cyt b and D-loop) and nuclear gene region (Rhodopsin). While
a total of 35 haplotypes were found in the Cytb gene region, a total of 132 haplotypes
were found in the D-loop (control region) gene region. A single haplotype was detected
in all stations for Rhodopsin. Also, the maximum likelihood trees based on Cyt b and
D-loop sequences suggested relationship of Bluefish populations from Türkiye and the
world. Results showed a low level of genetic differentiation between Bluefish
populations in the study area, but Aegean and Mediterranean populations are more
diverse than other populations due to migratory trait of this species.
