Haematological and Iatrical Response of Clarias Gariepinus (Burchell, 1822) Fed Different Commercial Feed and Farm-Made Feed

The C. gariepinus juveniles were stocked with a mean average weight of 15 grams in nine 1m×1m×1m concrete tanks at a density of 60 juveniles/fish and fed twice daily to satiation. There was an increase in the platelet (166×103/μL), red blood cell (2.05×106/μL), and haemoglobin concentration (9.3 g/dL) in the treatment fed the farm-made diet with a significant difference (p<0.05) compared to the concentration of the fish before the experiment. However, there was a corresponding decrease in the treatment fed the “S” diet with a significant difference (p<0.05) compared to the initial value. There was no significant difference (p>0.05) in the serum biological values of total protein, albumin and aminotransferase concentration of the treatment fed the “S” and “B” diets compared to the initial values. The treatment fed farm-made diet “L” showed relative reduction in total protein (4.7 g/dL), albumin (0.8g/dL), aminotransferase (180μL), and alanine transaminase concentration (18 μL) and significantly different (p<0.05) as compared to the initial value of total protein (6.3 g/dL), albumin (1.3 g/dL), aminotransferase (192.67 μL), and alanine transaminase concentration (30.33 μL). The composition of the feed diet could impact the haematological and iatrical responses of C. gariepinus juvenile.
