Abstract

There has been a great concern about the level of safety of surface waters, especially in developing countries where there is an exponential increase in water pollution and water-borne diseases. The aim of this study was to assess the effect of catfish pond effluents on water quality of stream water where five catfish farms were located.  Water samples were taken on monthly basis, 20 cm of below water surface from the streams that receive effluents from neighboring fishponds. Water quality indicators like dissolved oxygen, biochemical oxygen demand (BOD5), nitrate, nitrite, water temperature, ammonia and Hydrogen ion Concentration (pH) were examined in the sampled waters in accordance with the American Public Health Association standards. The average values of water quality indicators examined at effluents and non-effluents discharged sites of the stream indicated that water (24.6 ± 0.2, 24.2 ±0.1), (7.29±0.30, 7.30±0.10), (6.90±0.4, 7.07±0.1 mg/l), (0.40±0.04, 0.27±0.01), (3.77±0.26, 2.34±0.16 mg/l), (3.59±0.11, 2.80±0.02 mg/l) and (3.51±0.24, 2.46±0.21 mg/l) at (p≥0.05) respectively for temperature, pH, dissolved oxygen, total ammonia, total nitrogen, total phosphorus, and BODs. They were significant differences (P 0.05) excepts temperature and pH, between values obtained at effluents discharged and non-effluents discharged sites, indicating that improper discharges of catfish pond effluents could resulted into environmental contamination
