Some haematological parameters of inter-generic hybrid African catfish (Clarias anguillaris x Heterobranchus bidorsalis) were investigated to assess the ability of the hybrids to withstand culture conditions in North East Nigeria. The result shows that packed cell volume (PCV), red blood cells (RBC), Haemoglobin (Hb), mean cell haemoglobin concentration (MCHC) and platelets (PLT) were higher in pure line Clarias anguillaris. However, white blood cell (WBC) and lymphocytes (LYM) were higher in female H. bidorsalis x male C. anguillaris (Heteroclarias) hybrid. PCV, MCHC, Hb, and RBC of all the fish species observed in this study were within the healthy ranges for fish. The results of this study shows that Heteroclarias have haematological competence for survival in culture conditions in the region.
