Population Genetic Diversity of Bluefish (Pomatomus saltatrix L, 1766) in Coastal of Türkiye

Bluefish, is a commercially important fish species distributed the Türkiye coastal area. The high migration rates of Bluefish may prevent indirect speciation across its broad geographic distribution. The conservation and sustainability of the Bluefish populations require knowledge of the population`s genetic structure. There are no genetic studies on Bluefish in Türkiye and there are only a few studies in the world. In this study we investigated the population structure of this species in Türkiye coastal areas. COI and 16S rRNA gene sequences were performed in Bluefish samples collected from 14 regions. All stations are displayed low number of haplotypes for COI and 16S rRNA. In the COI gene region, total of 20 haplotypes was found whereas in the 16S rRNA gene region, total of 8 haplotypes was found. The results of both COI and 16S rRNA AMOVA analysis revealed that within population variation is less than among population variation It has been observed that Aegean and Mediterranean populations are more diverse than other populations. It is seen that the genetic differentiation among Bluefish populations in coastal Türkiye is low level and there are mixed individuals in all populations.
