ABSTRACT
Water quality is influenced by its physicochemical properties, and fish pond water is known to have an impact on the behaviour and wellbeing of the fish. Temperature, pH, alkalinity, hardness, electrical conductivity, turbidity, biological oxygen demand, nitrate, phosphate, and sulphate are the physiochemical parameters. Pond water samples were collected from Four different artificial fish pond (labelled 5, 6, 7 and 8) from the surface layer of the pond water and were analysed for its physicochemical characteristics using standard laboratory methods as designated by APHA. The results obtained were compared with the standard values given by WHO (World Health Organization) and USEPA (United State Environmental Agency). The result obtained revealed that the values of pH ( 6.95, 6.74, 6.65, 6.51), electrical conductivity (612, 239, 16, 162) µS/Cm, hardness (16, 20, 18, and 10)mg/ml, temperature (28.4, 28.3, 28, and 29) nitrate (2.51, 0, 3.01, and 3.22)mg/l, sulphate (23, 22, 9 and 76) mg/l, phosphate ( 3.622, 10.779, 5.654 and 5.419) mg/l within the standard values given by WHO ( World Health Organization) and USEPA (United State Environmental Agency). Although turbidity (90, 76, 28, and 266) NTU and TDS (302, 118, 7 and 79) mg/l were above the WHO and USEPA standard limit. The result of ( pH, electrical conductivity, hardness, temperature, nitrate, phosphate, and sulphate) which occurred within the standard values given the different regulatory bodies is an indicator that the fish pond water is favourable to the health and productivity of fishes, while (turbidity and total dissolve solid) which exceeded the standard values given by the different regulatory bodies is an indicator that the levels of these parameters in the fish pond water is detrimental to the physiological condition and productivity of the fish pond.
