Comparison of haematological indices, blood group and genotype of Clarias gariepinus (Burchell, 1822) and clarias anguillaris (Linneaus, 1758)

Abstract

The study on haematological indices of Clarias gariepinus and Clarias anguillaris was carried out to compare and contrast their blood group, genotype and haematological profile. Little is known about the blood group and genotype of the species. The knowledge of the blood group and genotype will be useful in the genetic study of the species. Test tube techniques based on agglutination tests was used for blood grouping, while the genotype was determined by hemoglobin electrophoresis. The haematological parameters, blood group and genotype of Clarias gariepinus (n = 12) and Clarias anguillaris (n = 12) males and females, were studied. The mean value of WBC count (μL) in C. gariepinus males was 1621.67±10.83 μL and females 9033.33±13.63 μL, respectively. The mean RBC counts for males were 3.0833±1.23 μL and females 3.85±0.46 μL and females 3.8500±0.46 mm 3, respectively. The mean MCHC for males and females were 33.15±0.1 g dLG 1 and 33.08±0.1 g dLG 1, respectively. Mean PCV for males was 51.62±6.79% and females 65.02±18.63%, respectively. Mean Hb. for males was 18.62±1.87 (g dLG 1), while the females had mean 22.12±5.823 (g dLG 1). The mean MCV for males and females were 172.17±43.03 and 169.300±31.64554 pg. The genotype of all the males and females were the same (AA). The blood group recorded 83% with O+, while 18% had AB+, respectively in the males and females. The WBC counts of males and females C. anguillaris were 7733.33±648.90 and 8033.33±16.47 μL, respectively. The mean RBC counts for males and females were 2.60±0.45 μL and 2.60±0.44 μL, respectively. The MCHC of both males and females were the same 33±0.00 g dLG 1. The mean PCV of males and females were 87.2±1.97 and 66.73±30.93%, respectively. The mean Hb for males and females were 29.77±1.20 and 22.47±10.13 g dLG 1, respectively. The mean MCV for males and females were 356.97±6.16 and 274±92.60 pg, respectively. The blood group, genotype and agglutination tests results were 83% Rh- O+, 18% Rh-AB+ and 100% AA, respectively and were similar to the pattern in humans.
