Abstract

Suspended solid in river is resource serious contamination. Suspended solid have a pernicious influence to fish and aquatic ecosystem. Flood and sediment and land use in river are largely[mainly] responsible of suspended solid. Especially, resuspension phenomenon of sediment will be dangerous effect to aquatic ecosystem. Study of fish and aquatic ecosystem on suspended solidus slight in fresh water. This study was basic research to manage fish and aquatic ecosystem on turbidity. It was conducted to analyze and monitor fish response on turbidity. Result in this study was confirmed the insensitive and die of fish on reduction of oxygen supply.

하천내의 부유물질은 장기간 지속할 경우 심각한 오염원으로 어류 등 수중생태계에 치명적인 영향을 줄 수 있다. 하천내 부유물징 발생원인은 홍수, 퇴적물, 하천변 이용도가 주원인으로 판단된다. 특히 퇴적물의 재부유는 심각한 수생태계 위험 영향이 될 수 있다. 부유로 인한 탁도에 대한 어류 연구는 담수의 경우 매우 미미한 수준이다. 본 연구는 탁도에 대한 하천내의 수생태계 관리 방안 제시를 위한 기초연구이다. 연구는 탁도에 대한 어류반응을 실험을 통해 모니터링하고 이에 대한 경향을 분석하였다. 실험결과 고탁도 구간에서의 수조에서 높은 농도의 부유물질로 인해 산소 공급이 방해되어 어류에 영향을 주는 것을 파악하였다.
