Asian clam is one of the snacks that is favored by the Malaysian especially the one from the east region of the Peninsular of Malaysia which are Kelantan, Terengganu and Pahang. Asian clam is the one of the bivalve mollusk species from the Cyniridae family. Then, fermented soy pulp(FSP) is the by- product of the soy industry since the industry only need the milk while the residue will be throw away however the fermented soy pulp has high content of protein hence it is suitable to be used as the animal feed. The study was aimed to examine the growth performance of the Asian clam (Corbicula fluminea) by using the fermented soy pulp as the feed source. In this study, the weight, height and length of the Asian clam were the parameter that has been recorded. All of the sample of Asian clam were farmed in the semi closed system for five week periods. 120 samples of Asian clam were used in this research and it were divided into two treatments. As a result, the best percentages (%) for the mean of weight, height and length increment from FSP treatment are 1.63 ± 0.34, 1.43 ± 0.13 and 1.57 ± 0.14 respectively. For the control treatment, the best percentages (%) of weight, height and length increment are 1.60 ± 0.33, 1.37 ± 0.15 and 1.60 ± 0.34 respectively. The finding of this result shown fermented soy pulp can be used as feed source of Asian clam
