Study of seasonal water quality assessment and fish pond conservation in Thanjavur, Tamil Nadu, India

Abstract

Life on the earth is never possible without water. Water is one of the essential constituents of the environments. This study was designed to assess the quality of pond’s water in Thittai panchayath village, Thanjavur District in Tamilnadu state has been evaluated on a seasonal basis from July 2015 to June 2016. The water Samples were analyzed for various physico-chemical characteristics like Colour, odor, turbidity, temperature, pH, DO, BOD, COD,Co2,salinity, total alkalinity and total hardness etc. The following ranges were obtained for the parameter assessed. pH(7.1-8.5), Temperature (26.9-31.90C) Electrical conductivity(290.30-405.10µs/cm), Dissolved oxygen (6.5-7.9mg/L), BOD (4.5-6.0mg/L), COD (4.8-7.0mg/L), CO2 (4.2-5.9mg/lit ), Calcium (78-108 mg/dl), Magnesium (58-73mg/dl), Salinity (10-19ppt),Total Alkalinity (68-95mg/l),Nitrate (3.0-4.1mg/l) and Chloride (15.3-39.8mg/l).The experimental values of various physico-chemical parameters of water samples results were largely within the WHO and ICMR standards limits. This study will aid fish farmers on the necessary treatment needed to effectively use water from this source for fish farming.
