The genetic diversity and population genetic structure of Culter alburnus were investigated using mitochondrial cytochrome c oxidase subunit I (COI) and ribosomal 16S subunit (16S rRNA) gene sequences. A total of 89 individuals from four localities were included in the analysis. Overall, 12 polymorphic sites were observed and 10 haplotypes were defined. The C. alburnus populations were characterized by high haplotype diversity (0.587 +/- 0.047) and low nucleotide diversity (0.00197 +/- 0.00073). Pairwise fixation index (F-ST) analysis indicated significant genetic differentiation among different populations. The hierarchical analysis of molecular variance (AMOVA) analysis also showed significant genetic divergence (phi(ST) = 0.3792, P < 0.01) among these populations. The present results suggest that subdivisions exist among four C alburnus populations, and should be considered as different management unit for effective conservation and management purposes. This study provides new information for genetic assessment and will be crucial for establishing fisheries management and strategies for this species.
