Alum is more effective and economical in removing clay turbidity from pond water sample. Alum requirement test was standardized to determine the amount of alum needed to floc clay particles in pond water. Alum requirement was standardized at 27 mgL-1 for pond water of Kharl and Research Station, Panvel. Alum treatment of turbid water caused marked reduction of turbidity and each mgL-1 of alum destroyed approximately 0.53 mgL-1of total alkalinity and thereby depressed pH. Growth and survival of Catla catla fingerlings in alum treated water compared to turbid water were studied by using ‘z’ and ‘t’ test respectively. Growth parameters of 15 day catla fry and 30 day fingerlings were found to be significantly higher in alum treated clear water than turbid water, whereas no significant difference was observed in survival. In conclusion, standardized dose of alum to turbid water can be useful to achieve good growth and survival of catla seed in turbid condition.
