Abstract：In the study, the genetic diversity and population genetic structure were analyzed in 8 populations of yellow catfish Pelteobagrus fulvidraco collected from Yangtze River and Huaihe River systems in Anhui province based on mitochondrial cytochrome b (Cytb) partial sequence. Overall, 49 haplotypes were identified with 48 mutation sites detected in total of 212 sequences in length of 1122 bp. The base composition of all sequences showed strong A/T bias and anti-G bias. The eight populations of yellow catfish were characterized by medium/high haplotype diversity (0.554—0.949) and low nucleotide diversity (0.00105—0.00221). The genetic differentiation index (0.2590), gene flow (1.4305) and the hierarchical analysis of molecular variance (AMOVA) revealed that there were consistently significant genetic differentiations among all populations. Statistical parsimony network based on haplotypes and phylogenetic tree based on population genetic distance consistently indicated that the populations from Yangtze River and Huaihe River systems clustered together and formed an clade, respectively. The findings suggest that yellow catfish populations from Yangtze River basin and Huaihe River basins in Anhui province have developed significantly divergent genetic structures due to geographic isolation and that provide basic information for genetic assessment, being crucial for establishing of fisheries management and strategies for the species.
