변화근 Fish Fauna of Mt. Juheul Department of Biology Education, Seowon University, Cheongju 361-742, Korea To clarify the structures and functions of ecosystem and to establish the methods for the conservation of natural resources in the Mt. Juheul, the author surveyed fish fauna at 8 stations from August, 2011. The collected species during the surveyed period were 13 species belonging to 5 families. Korean endemic species was Coreoleuciscus splendidus, Squalidus gracilis majimae, Microphysogobio yaluensis, Zacco koreanus, Cobitis hankugensis, Niwaella multifasciata, Liobagrus mediadiposalis, Coreoperca herzi and Odontobutis platycephal which showed a ratio of 69.2% in all collected species. According to relative abundance in the studies area, Z. koreanus and Rhynchocypris oxycephalus dominated. This species of Zacco platypus, Misgurnus anguillicaudatus and C. hankugensis were rare in the surveyed areas, which occupied less than 0.5% in relative abundance. Dominant species was Z. koreanus (St. 1, 2, 3, 5, 7, 8) and R. oxycephalus(st. 4, 6). According to analysis of community based on the diversity, evenness and richness indices, fish community seems to the more stable in St. 8. Assessment for ecological healthiness of the river, Station 2, 3, 7, 8 has excellent condition (A) and station 1, 4, 5, 6 has good condition (B). 서 론 (1,106m), (1,440m), (1,162m), (1,058m), (1,111m). 5.3km 2 ( 0.517km 2, 4.4484km 2, 0.247km 2, 0.052km 2 ), 1,176mm,..
