This article reports on the results of study on the induction of spawning and the artificial breeding of the clam (Cyclina sinensis)in earth ponds and plant respectively. A breakthrough in its intensive rearing was achieved. The average yield of 0. 26 cm aveage body length spats in 6988 m2 earth ponds was 3. 1119 × 104/m3. The average yield of the spats was 36. 73×104/m3 in breeding plant ponds with total seawater volume of 105 m3. Its average body lentgh was 0. 41 cm.
