Abstract

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.

1994년부터 1996년도까지 계류성 독립하천인 웅천천 수계의 보령댐 수몰예정지역을 중심으로 하여 6개지점에서 어류상, 주목할만한 어종 및 어류군집에 대하여 조사하였다. 본 조사지역에서 94년에서 96년 사이에 채집을 통하여 서식이 확인된 종은 11과 25속으로 총 29종이었으며 이중 9종은 한국특산어종이었다. 이 중 멸종위기종인 감돌고기와 퉁사리, 특산어종인 꺽지는 본 지역에서 확인되지 않아 절멸된 것으로 생각된다. 우세어종은 갈겨니, 피라미, 긴몰개가 우세한 그룹의 어종으로 나타났다. 지점별 평균풍부도는 0.68개체/$m^2$, 평균체적밀도는 1.45개체/㎥로 나타났으며, 종의 다양도는 상류와 하류보다는 중류가 가장 높게 나타났다. 군집간 유사도는 1군집과 4군집, 5군집과 6군집이 유사하였으나 유의한 차이는 나타내지 않아 전체가 유사한 군집으로 나타났다.
