The study describes growth and survival on different kinds of sediment improvements of early spats of the hard clam, Meretrix petechialis . Specimens of the mature hard clam were collected in the intertidal zone of Yeonggwang, Korea, July 2011. After transportation, early spats(shell length 196 ± 14 μm) collected in mature hard clam were used. Experiment period were July 7 to August 6 in 2011 (30 days). Sediment improvements used iodine(10 ppm), hydrogen peroxide(H 2 O 2 , 5 ppm), sodium hypochlorite (NaClO, 100 ppm), chlorine dioxide(ClO 2 , 100 ppm) and potassium permanganate (KMnO 4 , 5 ppm). After cultured during 30 days, shell length growth of hard clam were observed 1.04 ± 0.26 mm in sodium hypochlorite 100 ppm, 1.03 ± 0.25 mm in chlorine dioxide 100 ppm and 1.01 ± 0.28 mm in iodine 10 ppm. Survival rate were 31.4% in chlorine dioxide 100 ppm, 12.1% in sodium hypochlorite 100 ppm, 11.6% in iodine 10 ppm, 1.5% in hydrogen peroxide 5 ppm and 0% in potassium permanganate 5 ppm.
