P.). It is used mainly for irrigation &nbsp;and pisciculture &nbsp;by the nearby villagers. Diurnal variations &nbsp;in physico-chemical &nbsp;factors &nbsp;such as water &nbsp;temperature, &nbsp;pH, dissolved &nbsp;oxygen, &nbsp;free &nbsp;CO,, &nbsp;alkalinity and plankton (phytoplankton &nbsp;as well as Zooplankton) &nbsp;of the tank were &nbsp;studied. &nbsp;Fluctuations were &nbsp;found in water temperature, pH, dissolved &nbsp;oxygen, free &nbsp;CO and alkalinity. Free CO and alkalinity &nbsp;exhibited &nbsp;a negative &nbsp;relationship &nbsp;with &nbsp;the temperature. Abundance of plankton also showed &nbsp;a distinct diurnal variation.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;</p> ER -
