To clarify the structures and functions of ecosystem and to establish the methods for the conservation of natural resources in Mt. Inwang, the author surveyed fish fauna at 4 stations from August, 2014. The collected species during the surveyed period were 6 species belonging to 3 families. Korean endemic species was Zacco koreanus and Coreoperca herzi which showed a ratio of 33.3% in all collected species. In terms of composition ration, Rhynchocypris oxycephalus (79.3%), Pungtungia herzi (12.0%) and Zacco platypus (4.0%) were found to display high individual number. Dominant species was R. oxycephalus (St. 1, 2, 3, 4). According to analysis of community based on the diversity, evenness and richness indices, fish community seems to the more stable in St. 4. Assessment for ecological healthiness of the river, all surveyed stations has good condition (B). Calculation of the length-weight relationship of R. oxycephalus showed the value of constant a as 0.000002 and b as 3.33, and condition factor (K) was 0.82 on average.
