Abstract: Assessment of diurnal fluctuations and seasonal variations in physico-chemical parameters of freshwater ponds conducted on monthly basis. In the present study fluctuations and variability in water Temperature, pH, Dissolved oxygen, Alkalinity, Total hardness, Ammonia, Carbon dioxide and transparency have been observed. The water temperature, DO levels, pH, Alkalinity, Total hardness and Ammonia, Carbon dioxide and transparency were found to vary between 24 0C and 37 0C, 3.0 ppm and 17.5 ppm, 6.0 and 8.0, 200 ppm and 780 ppm, 210 ppm and 800 ppm and 0.01 ppm and 0.04 ppm,6.7ppm and 338 ppm and 21.5cm and 5 cm respectively in the farm at different months of the study period. Maximum values of temperature, dissolved oxygen, pH, Alkalinity, total hardness, ammonia, carbon dioxide and transparency were recorded as 32.9 0C at 16:00 (June). 17.5ppm at 16:00 (March), 8.0 at 14:00-16:00 (April), 570 ppm (May), 800 ppm (May), 0.04 ppm, at early hours in morning (January) and 338 ppm (March) and 21.5 cm (Feb), respectively. Also, the lowest values of above were, 240C between 2:00-6:00 (Jan, Feb & March) 3.0-4.0 ppm between 2:00-6:00, 6.2 (Feb & March), 200ppm (Dec), 177 ppm (Dec), 0.01 ppm during early and late morning hours, 6.7 ppm (Dec) and 5.0 cm (May) respectively. The pH value of the water was found slightly alkaline during the study period but there was no significant variation observed diurnally. DO and temperature were fluctuated significantly in diurnally and seasonally. Temperature, DO, pH, Alkalinity and hardness were recorded as maximum during summer than monsoon and winter. Based on the findings, the data useful for conversation and monitoring of the pond and the fish ponds are moderately soft category recommended for aquaculture.
