This study investigated the characteristics of fish communities and distribution of endangered species in the mid-upper reach of Geumgang River, Korea, from September to October 2021. A total of 17,177 fish of 11 families and 46 species were collected from 13 survey stations during the survey period. The dominant species was Zacco koreanus (relative abundance of 17.45%), and the subdominant species was Z. platypus (16.73%), followed by Acheilognathus koreensis (8.49%), Hypomesus nipponensis (8.27%), Pungtungia herzi (7.28%), Coreoleuciscus splendidus (6.80%), Gobiobotia brevibarba (6.58%), Pseudopungtungia nigra (4.67%), A. yamatsutae (3.77%), G. macrocephala (3.38%), and Rhinogobius brunneus (3.04%). Among the collected fish species, 21 (45.65%) were identified as Korean endemics, and two exotic species, Lepomis macrochirus and Micropterus salmoides, were also observed. There were six species of endangered species that were designated by the Ministry of Environment (Class I: P. nigra and Liobagrus obesus; Class II: G. brevibarba, G. macrocephala, Hemibarbus mylodon, and Coreoperca kawamebari). H. mylodon is also a natural monument designated by the Korea Heritage Service. The cluster analysis showed that the dominance index was low, while the diversity and richness indices were high, indicating a stable and healthy fish community. The mid-upper reach of Geumgang River has a well-conserved and diverse aquatic environment and is inhabited by many endangered species and natural monuments. Therefore, continuous attention and systematic management are required.
