The fish community was investigated from March to October 2007 in Gwangneung Arboretum. During the survey period, 22 species belonging to 9 families were collected. Among them, one species (Coitus koreanus) was classified as an endangered species in Korea, and exotic fish was Micropterus salmoides. Nine species (40.9%) were endemic species of Korea. Dominant species was R. oxycephalus (St. 1) and Z. platypus (St. 2-7). According to analysis of community based on the diversity, evenness and richness indices, fish community seems to be more stable in the St. 3. The distributions of Silurus microdorsalis, Cottus koreanus and Odontobutis platycephala were confined to the Bongseonsa Stream in the Wangsuk Stream watershed. When our data were compared with the previous data (1932), 17 species were not sampled, but 7 species could new taxa fiend its existence at the Bongseonsa Stream. We believe that Hemibarbus mylodon, Acheilognathus signifer and Zacco koreanus disappeared in the Wangsuk Stream watershed and A. signifer and Z. koreanus need to be restored at the Bongseonsa Stream.
