The largefin longbarbel catfish (Hemibagrus macropterus), a freshwater species endemic to China with fundamental economic importance, requires investigation into its genetic structure for effective management. In this study, we employed mitochondrial cytochrome b (Cytb) gene sequences and 14 microsatellite loci elucidate the of 195 individuals across eight distinct populations. Cytb analysis revealed haplotype number (H) 31, diversity (Hd) 0.853, nucleotide (π) 0.0127. Population neutrality tests indicated that Tajima’s D (−0.59467) Fu Li’s D* (0.56621) were not statistically significant, mismatch distribution exhibited multimodal pattern. Microsatellite mean alleles (Na), observed heterozygosity (Ho), polymorphic information content (PIC) all 18.500, 0.761, 0.808, respectively. UPGMA phylogram constructed based on distance identified two clusters, paired Fst values ranging from 0.108 0.138. These results suggest is in state dynamic equilibrium high diversity. Furthermore, there was significant differentiation between YB population other seven populations, indicating upper reaches Yangtze River should be managed as unit.
