The present investigation was carried out to study the impact of the parasitic infestation with Henneguya branchialis on the hematological parameters of catfish, Clarias garipienus. Therefore, 140 catfish specimens with average body weight of 257 plus minus 8.8 g were subjected to hematological investigations. The hematological analysis showed significant reduction in red blood cells (RBCs) count, hemoglobin (Hb) value, packed cell volume (PCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC), while total white blood cells (WBCs) count, mean corpuscular volume (MCV) were significantly increased in the infested catfish. This study concluded that H. branchialis causes physiological dysfunction on the infested fish by showing several alterations in hematological parameters that may often cause anaemia through reduction in RBCs count, hemoglobin value and packed cell volume.
