Abstract
This study was conducted to measured the survival rate of Crassostrea gigas according to the salinity when thewater temperature is high. In laboratory, the mortality test was performed on the C. gigas, we conductedexperiments at water temperature 20, 25, and 30℃, salinity was tested at intervals 5 psu from 0 to 35 psu. At 20℃, mortality was only seen at low salinity below 5 psu, on the other hand, above 25℃, the mortality was 100% at5 psu, and it was all survived at the above 30 psu. However, at a water temperature of 30℃ or higher, allindividuals died regardless of the concentrations of salinity. However, as a result of measuring the clearance rate,it was found that the feeding activity was performed only at 30 psu and 35 psu at 20℃ and 25℃, respectively. Andat 30℃, it was found that feeding activity was not performed at all concentrations of salinity. It was confirmed thatexposure to low-salt water during high water temperature affects the feeding and survival of C. gigas.
