The Yalu River fennel and the Heilongjiang fennel have certain differences in morphology (maxilla and gill raker number), but after molecular verification, it is a synonym of the Heilongjiang fennel and is now an invalid species. The Yalu River fennel is scarce and concentrated in streams above 1,000 meters above sea level in Changbai Town, Jilin. From the perspective of species protection, it can be regarded as an independent species for protection.
