This study was conducted to determine the haematological parameters of Clarias gariepinus juveniles, fed diets with Moringa oleifera leaf meal (MLM) as premix for 8 weeks. Fish mean weight of 12.5±0.04g was used. The experimental diets were formulated at 40% crude protein into three treatments of the same composition, but different inclusion levels of moringa, before processing into pelleted sinking feed. The treatments based on % mLM were 0, 0.5, 1.0 and 1.5. Both floating and pelleted sinking feeds were used. Each diet was fed to a group of thirty (30) juveniles of Clarias gariepinus per treatment at 5% body weight. Each treatment was replicated three times. The results showed that Treatment IV had the best haematological indices; and was not significantly different (P>0.05) from other treatments with respect to packed cell volume (PCV) 27.83±1.23; Haemoglobin (Hb): 8.73±0.81 and Red Blood Cell (RBC): 2.66±0.54. Treatment I equally had good haemotological Parameters: PCV (24.37±2.85); Hb (8.34±0.79); RBC (2.83±0.53), Platelet (123.45±7.81). Treatments II and III had higher levels of White Blood Cell (WBC) which ranged from 17.43±1.235 to 17.61±1.33. Haematological parameters were within the recommended range for fish health. This study revealed that moringa leaf meal (MLM) was best as replacement of premix; for improved performance for the tested parameters of Clariasgariepinus. Based on the findings of the study, it is recommended that 1.5%mLM inclusionrate as premix for enhancement of haematological parameters and better fish health of Clarias gariepinus.
