Abstract

The comparative study on haematology of Clarias gariepinus (Burchell, 1822) from two different aquatic environments was carried out to find out if habitat could affect the haematology of fish. Standard methods were employed in the haematological analysis. For wild fish, RBC was 2.06 ±0.358 x 10⁶ /mm³,  WBC 50.714 ± 6.465 x 10³/mm³,  PVC 21.6 ± 2.879%, Hb 7.06 ± 0.900 g/dl, MCV 111± 8.309 fl, MCH 38.430 ± 1.475pg and MCHC 32.85 ± 0.423% while for pond raised cat fish, , RBC was 2.372 ±0.346 x 10⁶ /mm³,  WBC 49.612 ± 6.596 x 10³/mm³,  PVC 16.90 ± 4.721%, Hb 7.54 ± 0.558 g/dl, MCV 90.33± 33.298 fl, MCH 35.638 ± 5.438 pg and MCHC 96.552 ± 42.98% respectively. There were no significant difference (p>0.05) in haematological characteristics of wild and pond raised Clarias gariepinus.
