Acute Haematological Effects of Sublethal Levels of Paraquat on the African Catfish, Clarias Gariepinus (Osteichthyes: Clariidae)

Haematological variables related to oxygen transport (total erythrocyte counts TEC, haemoglobin levels Hgb and haematocrit [packed cell volume, PCV]), calculated haematological indices (mean erythrocyte haemoglobin concentration MEHC, mean erythrocyte haemoglobin MEH and mean erythrocyte volume MEV)...

Summary:Haematological variables related to oxygen transport (total erythrocyte counts TEC, haemoglobin levels Hgb and haematocrit [packed cell volume, PCV]), calculated haematological indices (mean erythrocyte haemoglobin concentration MEHC, mean erythrocyte haemoglobin MEH and mean erythrocyte volume MEV) and total leucocyte counts TLC varied (p<0.05) between control and paraquat treated Clarias gariepinus following 96 h exposure. There were significant increases (p<0.05) in the levels of TEC, Hgb, PCV, MEV, MEH and MEHC while TLC decreased significantly (p<0.05). The variations observed were directly proportional to the toxicant concentrations.
