Genetic Investigation of Aral Wild Common Carp Populations (Cyprinus carpio) Using ddRAD Sequencing

Common carp (Cyprinus carpio) is a widespread freshwater fish species of the Cyprinidae family, one largest and most diverse families. The natural habitats C. carpio extend from Western Europe to South-East Asia. has remained an economically important in aquaculture for many centuries its production nowadays exceeds 4 million tons worldwide continues grow. taxonomy complicated, since this usually distinguished two, three, even four distinct subspecies. In present study, we used ddRAD-sequencing genotype 30 specimens five wild common populations Ponto-Caspian, Balkhash-Ile, Aral Sea geographical regions. It demonstrated that they differ at population level according F-statistics analysis. At same time, subspecies status aralensis not yet been confirmed. We found several loci can be as discriminant Ponto-Caspian populations. suggested (C. aralensis), which inhabits Balkhash-Ile basins, related or European carpio). Moreover, might ancestor Our results develop population-specific, high-density SNP marker panels, allowing trade control Eurasian Economic Union.
