Abstract
The intraspecific structure of the European anchovy (Engraulis encrasicolus) was studied on the basis of mitochondrial cytochrome b gene (cytb) fragment variability in 84 individuals from seven localities of the Black Sea and the Sea of Azov. The data on haplotype and nucleotide diversity and the values of neutrality tests suggested expansive growth of anchovy populations in the Azov-Black Sea basin. All samples from anchovy populations demonstrated a high level of haplotype diversity (Hd = 0.962). Two dominant haplotypes were identified, the frequencies of which were not directional, and they were present in all localities. Sequence analysis of the mitochondrial cytb gene fragment showed no differentiation between the Sea of Azov and the Black Sea subspecies.
