In order to comprehend the complex biological interactions occurring within an aquatic ecosystem, an assessment of its physico -chemical conditions hold a momentous position. Any changes that occur in these parameters have a direct impact on the biota inhabiting therein. The present study is an investigation that was carried out on the seasonal variations in the physico-chemical parameters of the Upparapalle fresh water fish pond in Warangal District. The study has been carried out for a period of one year i.e., from February, 2015 to January, 2016. The Temperature was ranging from 23.2 to 29.40ᵒC, pH was ranging from 6.90 to 7.40, DO content was from 7.6 to 8.4 mg/l, BOD ranged from 2.5 to 6.1 mg/l ,Total Alkalinity was 39.0 to 61.29 mg/l, TDS varied from 31.65 to 49.11 mg/l, Turbidity was ranging from 27.8 to 50.2 ppm, Free CO2 from 1.26 to 2.4 mg/l, EC was from116.0 to 154.62 µmhos/cm, Chlorides from 38.48 to 59.36 mg/l, Phosphates from 1.76 to 2.15 mg/l, Sulphates from 29.1 to 56.17 mg/l, Nitrates from 0.27 to 0.63 mg/l, Ammonia content from 0.95 to 1.57 ppm, Sodium from 4.0 to 6.9 ppm, and Potassium from 1.86 to 3.1 ppm. were analysed. These parameters vary from month to month and in three different seasons in an year i.e., Summer, Rainy and Winter seasons. The results showed that the variation in these parameters in four at the different sampling stations. The influence driven by these results showed that, This Fresh water fish pond is quite suitable to take up fish culture in Warangal district. That’s how the fish culture practices taken up in this pond certainly is an economical one, however the conclusion is drawn.
