Soil is one of the most important living, dynamic and crucial ecological factor which determines the fertility and productivity of any type of aquatic ecosystem due to its rich inorganic & organic components. Thus, ‘healthy soil’ is an essential prerequisite for successful fishery or pisciculture practices in lentic or lotic water bodies. The present paper deals with the analysis of some important chemical parameters of soil of Dhanauti river of East Champaran district of North Bihar near Motihari town. For the analysis of soil, pH, conductivity, bicarbonate, carbonate, phosphate (P2O5), organic carbon (matter), calcium, magnesium, silica, iron oxides (Fe2O3), aluminium contents (Al2O3) were examined during the entire study period i.e., January – December, 2010. All examined parameters were found to be in good concentrations which is ideal for successful pisciculture. pH was observed between 7.2 to 7.7 during the study period, providing ideal alkaline medium for pisciculture. Organic carbon (matter) was also found in good percentage, maximum in the months of January to March (3.3%) and minimum during the months of July to September (2.7%) while phosphate was recorded highest in the months of October to December (3.7 ppm) and lowest in the months of January to March (2.3 ppm).
