Spent engine oil, NPKfertilizer (15:15:15) and sewage effluent pollutants on growth and survival of Clarias gariepinus catfish were investigated for 70 days. Juvenile fish of length range 7.5cm to 10.6cm; and weight range 4.00g to 8.20g were used; and fish fed 5% body weight of conventional floating feed on daily basis. Temperature (0C), pH and dissolved oxygen (mg/l), mortality and growth rate were monitored. 35% mortality was experienced in NPK media; and 15% mortality was experienced in control experimental tanks. Specimens in control andNPK tanks survived to end of experimental period (70 days) with highest mean weight control tank (51.9g) and length (9.6cm); NPK specimen had mean weight 35.0g and length 8.4cm. Condition factor ‘K’ in control tank and NPK tank were: 0.98 and 0.93. Food Conversion Ratio (FCR) of control and NPK tanks were: 2.00 and 1.51. Food Conversion Efficiency (FCE) in control and NPK tanks were: 50.11% and 66.35%. Specific growth rate (SGR) {%/day} in control water tank was 1.47% per day, and NPK was 1.29% per day. Test statistic indicated there was no significant difference in growth/survival rate within surviving specimens of NPK and control environmental tanks.
