Abstract
Clams of the genus Corbicula were discovered for the first time in the downstream of the Don River in the area of the warm channel of the Novocherkassk State District Power Plant in 2017. They were identified as Corbicula fluminea according to conchiological features. The objective of this study is to confirm the species identification using the molecular genetic methods and determine the morphotype by shell morphometric indices: frontal (D/L) and sagittal (H/L) curvature (=Index of Roundness) and convexity ((H + D)/L). According to the results obtained, the Asian clam was assigned to the European invasive lineage of the FW5 haplotype, taxonomically assigned to C. fluminea and morphologically to the R morphotype.
