ABSTRACT
Used crankcase oil is disposed off indiscriminately and it eventually finds its way into the aquatic environment resulting in surface and ground water contamination by complex interacting chemicals and substances. Polycyclic aromatic hydrocarbons (PAHs), heavy metals, additives, antioxidants and trace levels of chlorinated solvents have been detected in used engine oil and these pose a great risk to fish populations and the human consumer of fish. This study (i) investigated the sublethal effects of water soluble fractions of used crankcase oil on feed conversion ratio (FCR), protein efficiency ratio (PER), specific growth rate (SGR), length and weight and muscle and liver glycogen of Oreochromis niloticus fingerlings, (ii) investigated the sublethal effects of the water soluble fractions (wsf) of used crankcase oil on the condition factor of O. niloticus fingerlings, (iii) assessed the bioaccumulation of metals in the liver, gill and muscle of O. niloticus fingerlings exposed to wsf of used crankcase oil, (iv) determined the sublethal effects of used crankcase oil on the haemotological indices of O. niloticus fingerlings, (v) investigated the effects of used crankcase oil on some selected enzymatic activities in O. niloticus fingerlings.The water soluble fractions (wsf) of the used crankcase oil was prepared using the method described by Anderson, Neef, Cox & HighTower (1974) whilethe 96hr static renewal bioassay technique was employed to obtain the median lethal concentration (LC50) from which the sublethal concentrations (definitive values) were made.One-way analysis of variance (ANOVA) was used to interpret the data on the mean concentration of metals in the experimental water and fish organs as well as the variations in mean values of liver and muscle glycogen and the growth performance and feed utilization of the experimental fish.Fishshowed significantly reduced weight (P < 0.05) with values of 1.1, 1.5, 1.6 and 1.8 g respectively.
