The freshwater fish fauna of the Tokyusan National Park was censused during June 1993 to November 1993 at 9 sampling sites to establish baseline data for natural conservation program on the National Park. Seventeen species included 7 Korean endemic species and/or subspecies(Acheilognaths koreunus, Squazidus gracilis majimae, Microphysogobio yaluensis, Phoxinus kumganensis, Cobitis koreensis koreensis, Silurus microdorsalis and Odontobutis platycephala) belonging to 5 families were collected in this region. Sixteen species were found in Kumkang and 8 species were found in Naktongkang, however, common species were Squalidus gracilis majimae, Microphysogobio yaluensis, Puntungia herzi, Moroco oxycephalus, Zucco temminckii, Misgurnus anguillicaudatus and Odontobutis platycephala. Dominant species of this region were Moroco oxycephalus, Zacco temminckii, Odontobutis platycephala. The final aims of this study were not only accumulate baseline data on the osteology of Korean freshwater fishes which were collected at those streams during June 1993-November 1993 with soft X-ray radiography, but also evaluate the suitability of osteological analyses on the environmental damage to fish.
