Abstract: Basic haematogical parameters in African catfish, Clarias gariepinus fed ascorbic acid supplemented diets were evaluated in this study. Clarias gariepinus fingerlings weighing 6.02&pplusmn;0.4g were randomly distributed into glass tanks of 60�45�45 cm3 dimension at ten fish per tank in a triplicate treatment. Five isonitrogenous and isocalorific diets containing 40% crude protein was formulated. Endogenous concentrations of Ascorbic Acid (AA) were monitored in the diet, this was supplemented with graduated concentration of ascorbyl-2-polyphosphate at 0 (Control) 50, 100, 150 and 200 mg AA kg 1, in Treatment 1, 2, 3, 4 and 5, respectively. Fish were fed practical diets twice daily at 900 and 1600h. Weekly weighing of fish was done and two Fishes were removed from each aquarium for blood analysis, The blood was collected from cardiac puncture of fish using 2ml disposable heparinized syringes, with Tetra Acetic Acid (EDTA) usad as anti-coagulant, the haematological data collected were subjected to statistical analysis. Haematological studies on Clarias gariepinus conducted in this study after the feeding trials indicated that fish fed scorbutic diets had significantly lower (p< 0.05) pack cell volume, haemoglobin concentration and red blood cells, while the highest white blood cells was recorded in this treatment as 4.25&pplusmn;0.14 �10 mm-3 Among the derived haematological parameters only the mean corpuscular volume was significantly different (p< 0.05).
