The potential of blending soaked moringa (Moringa oleifera) leaf and fermented moringa kernel as a substitute for fishmeal in the diet for Clarias gariepinus was investigated. The leaves were soaked overnight while the seeds were defatted and subsequently fermented with Rhizopus stolonifer.  Four approximately isonitrogenous (40 % crude protein) and iso-energetic (20 kJ/g) diets were formulated to contain graded levels (0, 20, 40 and 60 %) of mixture (1:1) of soaked leaf and fermented kernel of moringa. The diets were fed to triplicates group of C. gariepinus (average weight, 8.87 ± 0.02 g) for 56 days. Growth performance in terms of weight gain and specific growth rate in the group that received control diet was significantly higher (p<0.05) than those that were reared on diets containing 40 and 60 %  mixture of soaked moringa leaf and fermented kernel but statistically similar (p>0.05) to the group fed with 20% of the mixture. The feed conversion ratio was statistically similar (p>0.05) in the control and dietary treatments. The haematological profile of the control group was similar (p>0.05) to all other treatment groups in all the parameters examined; suggesting that there were no deleterious health effects arising from incorporation of processed moringa leaf and kernel in the diets for C. gariepinus.
