## Abstract
Abstract This study aims to determine the effect of ocean acidification and temperature on growth, survival, and shell performance of fluted giant clam ( Tridacna squamosa ). Juvenile fluted giant clam put into an aquarium which is given a combination of CO 2 pressure treatment (415, 1000 and 1800 ppm) and temperature (30, 32, and 34°C). Measuring the length, width and height of the shell perform in every two weeks for five times. CaCO 3 content and shell strength was test at the end of the study. The best growth of shell length, shell width, and shell height in the treatment of CO 2 concentrations of 415 ppm and temperatures of 30°C were 23.28 mm, 11.51 mm and 0.69 mm respectively. Survival live also obtained in the treatment of CO 2 concentrations of 415 ppm and temperatures of 30°C and CO 2 concentrations of 415 ppm and temperatures of 32°C each of 100%. The strength of the shell and CaCO 3 content decreased in the treatment of CO 2 concentration and high temperatures. Higher concentration of CO 2 and increased temperature negatively affected the growth of length, width, survival of scales, reduced strength and the CaCO 3 content of shell.
