Physico-chemical Properties of Denbi Reservoir for Fish Production in Bench Maji Zone, Ethiopia

Abstract

Water quality is made up of physical, chemical and biological factors which influence the use of water for fish culture purposes. The objective of this study was to analyze physicochemical properties of water in Denbi reservoir. Field and laboratory work were conducted to generate the data. The collected data were analyzed by using descriptive statistics and one-way ANOVA test. The result of the study showed that the mean and standard deviation of physicochemical parameter of water obtained were as follows: Temperature (25.14±1.12^oC),pH (8.25±0.31), Conductivity (48.94±1.55μS/cm), TDS (24.16±0.49 mg/L), Turbidity (24.54±3.02 NTU), transparency (33.90±5.18cm), Total hardness (0.27±0.03 mg/L), Calcium hardness (1.57±0.30 mg/L), Iron (0.005±0.003mg/L), Manganese (0 mg/L), Nitrates (0.07±0.03 mg/litter) and Sulphate (0.15±0.01mg/L), respectively. The Physic-chemical properties of water in Denbi reservoir indicated that it is fit for fish production except total hardness and calcium hardness which were below the standards.
