The effect of mannan oligosaccharide (MOS) on the water quality parameters of a recirculatory aquaculture system growing Indian major carp Labeo rohita was evaluated out for a period of 120 days. The basal diet in all trials contained 35% protein with different dosages of MOS at 0.0, 0.15, 0.30 and 0.45% in triplicates. Uniform sized fish fingerlings averaging 1.3g were used for the experiments. The different water quality parameters viz, temperature, PH, dissolved oxygen, free carbon dioxide, total alkalinity and ammonia-nitrogen were found to vary during the culture period.
