STUDIES ON PHYSICO-CHEMICAL AND BIOLOGICAL PARAMETERS RELATION TO BLUE REVOLUTION WITH REFERENCE TO YELDARI DAM, TALUKA JINTUR, DIST. PARBHANI (M.S.), INDIAV.B. Pawar and Kshama Khobragade
The present study has been carried out to investigate the effect of some physical, chemical and biological aspects of Yeldari dam. The parameters like pit, Temperature, alkalinity and free carbon dioxide have been studied for 12 months period in 2006. Biological parameters like phytoplankton, zooplankton and fish production water are indispensable and one of the most precious of natural resources on this planet. Water is mostly needed by man for the Drinking, Irrigation, Industry and domestic needs. The dam situated between two mountain hills, its catchment area is on top of the hills. These physical parameters were studied in every month in second week. The difference between air and water temperature range was 2 to 7°C in first six months and 2 to 6°C in second six months. It was observed that there was a close relationship between the turbidity and transparency. The transparency values were lower in monsoon compared to summer and winter months. The p1-1 of darn 6.9 to 75 in 12 months, a close co-relation between pH and bicarbonate alkalinity Dissolved oxygen recorded high in winter than monsoon and less in summer its range is 1.4 mg/L to 7.2 mg/L. Free carbon dioxide value is more in winter and less in summer season. Carbonate alkalinity is maximum in number and minimum in winter. The biological parameters, concerned with phytoplankton spirogyra, nostoc are more in number in summer and winter and totally absent in monsoon season. Whereas Zooplankton concerned Cyclops, birchonus and eurycerus are more in summer and winter season and less in monsoon season. Through the year Cyclops are dominant Zooplankton. So for fish fauna studied near about seven families and 5 order of fishes were recorded. The major crops are maximum like catla catla and cyprinus carpi() are excellently fast growing fishes. The total fish production of this dam in 236, decreased so as compared to 2004 to 2005. The tish production in Yeldari Dam Tq. Jintur, Dist. Parbhani is better than other darn regarding to the fish fauna.
