초록

본 연구는 탄소 및 질소 안정동위원소비를 이용하여 하천에서 환경변화의 지표로 활용할 수 있는 부착조류의 먹이원으로서 기여도를 파악하고자 하였다. 연구지역인 탐진강은 지류를 통해 유입되는 외래기원물질의 영향으로 상류에서 하류로 갈수록 높은 영양염의 농도를 나타냈으며 이와 더불어 상위섭식자인 어류의 질소 안정동위원소비의 증가가 관찰되었다. 또한 탐진강에서 채집된 저서성대형무척추동물과 어류의 ${\delta}^{13}C$ 값이 상류에서 하류로 이동하면서 무거워지는 경향을 나타내었다. 이는 탐진강 하류 수역에서 무거운 ${\delta}^{13}C$ 값을 보였던 암석 부착조류가 먹이원으로서의 기여도가 높아진 결과로 판단된다.

To investigate foodweb of aquatic ecosystem in the Tamjin River, carbon and nitrogen stable isotopes ratios of aquatic organisms, as well as environmental indicators based on the water, were determined in this study. Various organisms such as fishes (Coreoperca kawamebari, Zacco platypus, Cobitis lutheri, and Pungtungia herzi) and periphyton (epilithon and epiphyte), and particulate- and coarse particulate organic matters (POM and CPOM) were collected in upper (Tamjin River, Yuchi Stream, and Omcheon Stream) and lower (TJ-1~TJ-5) reaches of Jangheung Dam. The nitrate concentration and ${\delta}^{15}N$ signature of POM and organisms (invertebrates and fish) were found to be more enriched toward the downstream section of the river. It was determined that allochthonous matter occurring from a tributary alters the chemical character of water, as well as the isotopic signature of organisms contained therein. Attached algae (ephilithon) were identified as a base component of the benthic foodchain further downstream.
