| The fish fauna, notified species, and fish community was studied at the six stations in a 18km section of the Ungchon stream, a mountain stream in Korea, where a new dam is planned from 1994 to 1996. Twentynine species (11 families, 25 genera) were found. Nine species were endemic to Korea. The Dominant specie in the studied area were Zacco temmincki, Z. platypus and Squalidus gracilis majimae. Some of the korean endemic species (Coreoperca herzi) including the Korean endangered species such as Pseudopungtudgia nigra and Liobagrus obesus were not found in this stream anymore. The average of area density was 0.69 individuals per square meter and the volume density was 1.45 individuals per cubic meter. Species diversity was highest in the middle region. According to community correlation coefficients of six stations, similality coefficients of station one, four, five and six were higher than others, but no significant difference in the composition of fish fauna was found between six study staions. |
