Abstract
Elevated concentrations of suspended solids in the marine enrironment caused by coastal developments have threatened to the marine ecosystem. Effects of suspended solids on the mortality and the modifications of glycogen levels of abalone, Haliotis discus hannai were studied. Abalone were exposed to suspended solids with concentrations of 0 (control), 1,000, 1,500 and 2,000 mg/ L for 96h. These suspended solids had no effect on the mortality of abalone. Significant decreases in the glycogen content of soft tissues were observed over 1,500 mg/ L concentration of suspended solids. These results suggested that abalone could tolerate a high level of suspended solids. However, it is necessary to observe further the long term effects of suspended solids on the physiological responses of abalone.
연안개발에 의하여 해양으로 유입되는 부유토사는 해양생태계에 많은 영향을 미칠 것으로 판단된다. 따라서 본 연구에서는 참전복, Haliotis discus hannai 치패를 이용하여 부유토사 농도 변화에 따른 폐사율 및 글리코겐 함량 변화에 대해 알아보았다.
