【 摘 要 】

Recirculation aquaculture system is a culture technique which water conserve and reduce the waste discharge into aquatic environment. Trickling filter is the one of filter that common used for close system. Many kinds of substrate are able to use as a trickling filter to reduce the waste from aquaculture activity. The experiment aims to examine the effectivity of different substrate on growth, survival, and water quality of common carp. The different substrate as a treatment namely A) bio ball, B) bamboo, and C) gravel stone. The result showed that common carp cultured at A and B treatments on specific growth length (1.35±0.01 and 1.36±0.02%), specific growth weight (2.09±0.020 and 2.05±0.018%), and survival rate (86.67±2.44 and 87.89±1.83%) were higher than that of C treatment (0.81±0.03%, 1.74±0.075%, and 79.69±1.67%) (P
