Abstract

The ponds under investigation of Sasaram namely Sher shah suri tomb Pond, Amra talab, and Salim Khan pond  are very old ponds and have historical value. The ponds were constructed with an idea to water harvest the rainwater for agricultureal and domestic purposes. In the long run when population has increased the periphery of the water bodies has inhabited by dense population and releases the untreated waste in the water bodies leading to eutrophication of the pond , dense algal bloom etc. due to negligence of the people the beautiful ponds are polluted and not even used for the benefit of the local person . There is no scientific fish culture in the ponds for economic and employment gain. The nutritional status of the pond soil i.e pH (7.1-8.0) slightly alkaline. The value of soil Nitrogen (520.0-978.1mg/kg) Phosphorus 11.2-17.4mg/kg) Potash (103-501mg/kg.) and organic carbon % of the pond(2.1- 4.08%) keeps the ponds under productive categories. In totality, water temperature depends on geographical location and climatic conditions such as, rainfall, humidity, cloud cover etc. The  air temperature of the three ponds under investigation 24.43±5.3   and  water temperature 24.68±5.24. the pH was 8.1, Dissolved oxygen 6.7ppm, free carbondioxide 16.1 ppm, total alkalinity 199 ppm, Conductivity 2.44, transparency 30.9 cm, BOD 0.28ppm,and plankton 0.28 ml/50 lits of water. The ponds are not under any commercial use of fish culture though it has got potentiality and can bring the income and employment in the area through fish culture. The fish species may stocked as per the primary productivity of the ponds for utilization of fish culture which will also improve the water quality.
