The comparative haematological characteristics of both sexes of African Catfish Clarias gariepinus in Cross River, Cross River state was determined. The blood parameters determine includes Red and White Blood cells counts, Haemoglobin, Haematocrit, Mean Cell Haemoglobin Concentration, Mean Cell Volume, Mean Cell Haemoglobin, Protein, Sodium, Potassium, Lymphocyte, Platelet, Red Cell Distribution with standard size, Red Cell distribution with Corpuscular Volume and Mean Cell Haemoglobin Concentration. The blood cell count were higher in male (WBC, RBC, HGB, HCT, MCH, PLT, LYM, MCHC, RCD-WSS and RCD-WCV) with mean values (1.60±24.71, 1.28±8.27, 9.38±4.02, 17.75±8.59, 47.78±9.09, 3.44±29310.43, 91.14±9.70, 46.20±12.55, 46.81±12.46 and 20.52±17.16) except MCV which was higher in female than male with mean value (98.54±42.09). The red and white blood cell counts did not positively correlate with the physical parameters length and weight. There were significant correlations between weight of female and Male weight (at p< 0.05), Red Blood Cell of female negatively correlated with Male Haemoglobin (at p<-0.05), white blood cell of female negatively correlated with male Platelet (at p <0.05), female fibre did not correlate with any of the male parameters. The result reveals that all the haematological and biochemical parameters of the male were higher than the female except the electrochemical parameters which were examined to be the same. The result will serves as baseline information for disease and pollution assessment in a fisheries management activities.
