Abstract: The effect of water quality parruneters Temperature, Dissolved, Oxygen, pH Turbidity on growth, survival and specific growth rate of Clarias gariepinus fry was detennined. The range of Temperature, Dissolved Oxygen and pH were 28.0-28.8°c, 3.4-5.6mgll and 6.4-7.1. respectively. After 56 days of rearing the fmal mean weight of control, Treatment one, two, three and four were 33.20g, 30.70g, 26.95g, 34.21g, and 29.19g. respectively. The result for T -test, analysis of variance revealed that there were significant different (P< 0:05) in the final mean control and final mean treatments. Duncan multiple range test revealed that T3 was significantly higher than the control and other treatments (T], t4, and T2). Tl was also not significantly different from T4 and T2. T4 was not significantly higher than T2, which had the lowest growth rate, significantly lower than the control. The survival rate for control, Treatment one, two, three and four after 56 days were 84.75%>, 84.750/078.100/0, 87.75% and 82.50~0 respectively. It was therefore concluded that Dissolved Oxygen is a critical in the growth of Clarias gariepinus fry during the experimental period
