The Black and Caspian Sea Sprat, or Tyulka (Kilka or Sardelka) Clupeonella cultriventris (Nordmann, 1840) (Actinopterygii: Clupeiformes) is a small pelagic species, the most abundant nonindigenous fish species of the Volga-Kama basin playing an important role as one of the key elements of food webs in freshwater ecosystems. In this paper, we characterize the complete mitochondrial genome of Tulka from an unambiguously adventive population of the Upper Volga (58.38861 N, 38.32694 E). Voucher identification was performed both by morphological characters and a DNA sequence blast against the GenBank international database. For sequencing of the complete mitochondrial genome, a classical Sanger sequencing was applied with the PCR product from a set of 48 primer pairs giving a complete overlapping and unambiguous reading of each nucleotide in at least two replications. Annotated full mitogenome of C. cultriventris with length of 16650 bp has a gene arrangement characteristic of (and conservative) Clupeiformes contains 22 transport RNAs, 13 protein-coding genes, two ribosomal RNAs, and a single noncoding region. This mitochondrial genome demonstrates a 98.7% similarity to the previously studied one from the Black Sea. Based on these data, there are no sufficient reasons to separate the freshwater Sprat of the Volga-Kama region into a separate taxon.
