Abstract

This study investigated the difference in fish community structures in a main channel and an isolated former channel, considering the environmental factors in the Mangyeong River, Korea. Principal component analysis (PCA) with environmental factors showed that former channels were composed of a fine substrate covered by in-stream vegetation, whereas the main channel was covered by a wide range of substrates with a higher dissolved oxygen and conductivity. The result of the hierarchical cluster analysis with species abundance delineated to the four main groups; three abandoned channel groups and one main channel group. Non-metric multidimensional scaling (NMDS) showed that fish community structures of each study site differed from environmental factors: former channel fish communities were positively related to in-stream vegetation cover, whereas main channel fish communities were positively associated with dissolved oxygen and conductivity. The results indicated that channelization, where there was a separation between the former channel and the main channel, had detrimental effects on fish community structures of both the main channel and the abandoned channel in the Mangyeong River. In conclusion, this study suggested that the connectivity between the main channel and abandoned channel were required to enhance both habitat structural diversity and species diversity of the Mangyeong River.

본 연구는 하천에서 격리된 구하도와 본류에서 어류 군집 구조의 차이를 비교하기 위하여, 만경강에서 2곳의 본류와 단절된 구하도를 선정하여 환경 요인과 어류 군집 구조를 조사하였다. 측정된 환경 자료를 이용하여 주요인분석을 실시한 결과, 구하도는 하상이 주로 진흙과 모래로 이루어졌고 식생 피도가 높은 반면 본류는 수로 폭이 넓고 하상이 왕자갈, 잔돌, 호박돌 등 다양한 하상구조를 보였고 용존산소 및 전기전도도가 높게 나타났다. 어류 자료를 사용하여 군집분석 결과, 구하도 군집과 본류 군집으로 뚜렷이 구분되었다. 구하도는 호소 및 소하천에 서식하는 어류 군집 구조가 나타났고, 본류는 강과 같은 대형하천에 서식하는 어류 군집 구조를 나타냈다. 비모수다차원척도법 결과에 의하면 구하도에 분포하는 어류는 식생 피도와 높은 양의 상관관계를 가진 반면 본류에 분포한 어류는 용존산소, 전기전도도와 높은 상관관계를 보였다. 본 연구 결과, 구하도는 본류와의 연결성이 단절되면서 본류와 비교할 때 어류 서식 환경이 완전히 달라짐으로써 어류 군집 구조가 큰 차이를 보이고 어류의 산란처 및 은신처 기능도 상실한 것으로 판단되었다. 따라서 하천의 어류 생물다양성 증진을 위하여 구하도의 횡적 연결성을 복원하기 위한 노력이 필요하다.
