The effects of replacing soybean meal with Jatropha curcas seed meal on haematology and biochemistry of the blood of African Catfish (Clarias gariepinus) were evaluated. Two hundred and twenty five (225) juveniles of Clarias gariepinus were acclimatized for a week, weighed and allotted into five dietary treatments; DT1, DT2, DT3, DT4 and DT5 containing 0, 25, 50, 75 and 100% Jatropha curcas replacement levels with soybean meal respectively. The diets were isonitrogenous and isolipidic. Each treatment was replicated three times with 15 fish per replicate. Fish were fed 5% body weight on two equal proportions per day. The results from the study indicated that the haematological and biochemical parameters of Clarias gariepinus exposed to different dietary treatments in this study was not significantly different between the control diet and test diet D2 (25% replacement level) except for WBC. Generally, there was a lack of trend in the haematological parameters in the blood of Clarias gariepinus exposed to different dietary treatments. However, the values of some haematological parameters recorded in this experiment were within the range of normal haematology of a healthy fish.
