ABSTRACT

To clarify the structures and functions of ecosystem and to establish the methods for the conservation of natural resources in the Mt. Seongju, the author surveyed fish fauna at 8 stations from August , 2013. The collected species during the surveyed period were 19 species belonging to 8 families. Korean endemic species was Rhodeus uyekii, Coreoleuciscus splendidus, Squalidus gracilis majimae, Zacco koreanus, Iksookimia koreensis, Pseudobagrus koreanus, Silurus microdorsalis and Odontobutis interrupta which showed a ratio of 42.2% in all collected species. Exotic fish was Micropterus salmoides, and they compried 0.2% of total catched. According to relative abundance in the studies area, Z. koreanus, Rhynchocypris oxycephalus, Zacco platypus and C. splendidus dominated. This species of R. uyekii, Acheilognathus lanceolatus, Hemibarbus longirostris, Pseudogobio esocinus, S. microdorsalis, M. salmoides and Monopterus albus were rare in the surveyed areas, which occupied less than 0.5% in relative abundance. Dominant species was R. oxycephalus (St. 1, 4, 5), Z. koreanus (St, 2, 3, 6), Zacco temminckii (St. 7) and Z. platypus(St. 8). According to analysis of community based on the diversity, evenness and richness indices, fish community seems to the more stable in St. 7. Assessment for ecological healthiness of the river, Station 3, 6 has excellent condition (A) and Station 1, 2, 4, 5, 7, 8 has good condition (B).
