Study Of Physico-Chemical Characteristics Of Water And Soil In Relations To Fish Production In Motia Lake Reservoir

Abstract

Study of Physico-Chem- ical Characteristics of Water and Soil in Relations to Fish Production in Motia Lake Reservoir. J Atmos Earth Sci 2: 006. Abstract Present studies were carried out for physico-chemical parameters of water and soil of Motia Lake Bhopal, Madhya Pradesh, India. The aim of the study was to establish the safety of water and fishes from the Lake. Different physico-chemical parameters such as pH, Electrical Conductivity (EC), Dissolved Oxygen (DO), Total Alkalinity (TA), Total Hardness (TH), Chloride (Cl), Nitrates (NO 3 ), Phosphate (PO 4 ), Turbidity and Total Dissolved Solids (TDS) of lake water were investigated during pre-monsoon, monsoon and post-monsoon period. The soil parameters such as pH, EC, phosphorus, nitrogen, potassium and organic matter were also studied in different sessions. The value of pH, EC, DO, TH, TA, Ca, Mg, Cl, NO 3 , PO 4 were recorded higher during pre-monsoon period in lake water. In soil sample, pH, EC, nitrogen was found higher in post-monsoon during study period. The results on physico-chemical parameters of water and soil clearly indicate highly productive nature of the Motia Lake. The water quality parameters showed maximum values during pre-mon-soon compared to rainy and winter seasons. It was inferred from the results of water quality and soil analysis that Motia lake was produc- tive in nature.
