The Chinese sucker (Myxocyprinus asiaticus), native to China, faces decline due to pollution and overexploitation, and is now a protected species.
Researchers analyzed the D-loop region of mitochondrial DNA from 8 samples, revealing 32 genetic variations and a mutation rate of 0.033, indicating a degree of genetic diversity among individuals.
Comparison of the Chinese sucker's D-loop with that of Moxostoma robustum showed a higher mutation rate for the Chinese sucker, suggesting a more complex population structure warranting conservation efforts.
