Physical & Chemical Characteristics of Blood of two Fish Species (Oreochromis niloticus and Clarias lazera)

The aim of this study is to determine normal range of fish blood (Oreochromisniloticus and Clarias lezera) in Khartoum State. Sixty samples of fish were examined, 30 samples of Oreochromis niloticus and 30 samples of Clariaslazera. The fish were selected from three different sites in Khartoum State, Jebel Awlia Reservoir, College of Science and Animal production Technology Fish Farm and Golden Arrow Co. Ltd. The experiment was conducted for one month, and the result revealed that the total protein percentage of Oreochromis niloticus range between (13.39 ± 39.25 mg/dl), Glucose (152.75 ± 56.45 mg/dl) and Urea (34.5± 22.95 mg/dl). The Red Blood Characteristics were Haematocrite (PCV) (16.3± 9.45%), Haemoglobin Hb (3.5±2.0 mg/dl), White blood cell (WBCs) (80.2± 79.7), Red Blood Cell (RBCs) (2.6± 1.5), MCV (74.1±40.6 ft), MCH (26.9±16.6 pg). The total protein of Clarias lazera was (157.85±193.35 mg/dl), Urea (45.45±23.4mg/dl) and Glucose (91.72± 128.35 mg/dl), while Red Blood Characteristics were Haematocrite (PCV) (20.15±4.7%), Haemoglobin Hb (9.95±2.8 mg/dl), White Blood Cells WBCs (119.23± 64.63), Red Blood Cells RBCs (2.6±0.59), MCV (76.49± 24.5 ft). MCH (36.25± 13.85 pg).
