Theblood condition of the fish is crucial in meeting the health, food, economic and post-harvest needs of fish farmers and consumers. In this study, the hematological conditions of live and sacrificed samples of two commercially important teleosts, Clariasgariepinus (African mud catfish) and Channaafricana (Snake head fish), obtained from Egbe dam located in Ekiti State, southwest Nigeria were studied. Blood samples were collected from tranquilized live fish by puncturing the anal fin vein using 23G x 11/4” sized heparinized plastic syringe and later sacrificed by percussive stunning for post-mortem blood sample collections. Standard hematological analytical procedures were used in the assessment of the various blood parameters. The results obtained evoked significant differences (P<0.05) in the Packed Cell Volume (PCV), White blood Cell Counts (WBC), Red blood Cell Counts (RBC), Hemoglobin (Hb) and Blood platelet (PLT) of the live samples of the two teleosts. C. gariepinus had higher values of blood parameters profile than C. africana in all the analytical assessments with a higher 2:1 WBC counts, suggesting a lesser environmental and pathological stressors for C. africana at the time of sampling. There were no statistical differences (P>0.05) in the blood Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), and Mean Corpuscular Hemoglobin Concentration (MCHC) of the two live fish species. The results of the post-mortem analysis of the blood parameters revealed significant differences (P<0.05) at the different intervals of blood collection with the highest rate of decline in the blood profile within the first 2hours of death. Rigor-mortis had no visible impact on the decreasing status of the blood profiles of the two teleostean fish because the muscle stiffening was delayed for about 6hrs after the initialization of the post-mortem study. The results obtained in this study will serve as baseline hematological parameters for use in monitoring of fish health and preservation.
