Hematological analysis of Clarias garipinus and Oreochromis niloticus from Gwagwalada Market, Abuja, Nigeria

Tilapia (Oreochromis niloticus) and Catfish (Clarias gariepinus) are very common fish but little is known about their physiology. This study was carried out to determine the complete hematological profile of catfish (Clarias gariepinus) and Tilapia (Oreochromis niloticus) both of which were obtained from a local fish vendor in Gwagwalada market. They were anaesthesed and analysed and the values of the haematological parameters are as follows: for Clarias gariepinus, 124.19 (white blood cell count), 2.35 (Red blood cell count), 131.94fl (Mean corpuscular volume), 32.05% (Packed cell volume), 10.68g/dl (Haemoglobin), and 32.60 g/dl (Mean corpuscular haemoglobin) and24.16 (Mean corpuscular haemoglobin concentration) were calculated. For Oreochromis niloticus, 121.65 (White blood cell count), 2.24 (Red blood cell count), 132.21fl (Mean corpuscular volume), 30.07% (Packed cell volume), 10.23g/dl (Haemoglobin), 35.98g/dl (Mean corpuscular haemoglobin) and 30.48 (Mean corpuscular haemoglobin concentration) were calculated. Slight differences were observed in the values of both species with Mean corpuscular volume (MCV) and white blood cell count (WBC) having the highest mean values while red blood cell count and hemoglobin having the lowest value among both species.
