Abstract

The research work was conducted to measure the water quality parameters during the period of July 2013 to December, 2013 at Moyna. Physico-chemical characteristics of water & soil very significant in paddy cum fish culture field which in general controls the productivity of the water bodies. Bottom soil plays an important role in the fertility of the water body. It provides shelter and food to the bottom micro-biota which help in the mineralization of organic bottom deposits and governs the storage and release of nutrients in the water phase. In general, therefore, the physical &chemical properties of water in a water body are more or less a reflection of the properties of its bottom soil. Chemical factors such as pH, DO, alkalinity, free Carbon dioxide, total Hardness, Ca, Mg, specific Conductivity etc. are also play a vital role in the biological process in water bodies. Sediment characteristics values depict productive range for better rice as well as fish production. The physico-chemical parameters of the water of the impoundment reveal that water level supported a conductive caring capacity resulting in better fish growth.
