Abstract
This study has investigated the changes of haematological profile of Clarias gariepinus exposed to sub-lethal concentration of deltamethrin over a 28 days exposure period. Sub-adults C. gariepinus (weight 134.21± 43.01g and length 17.34± 5.92cm) were exposed to control (0.00) 0.005, 0.011, 0.022 and 0.044 ppm concentrations of deltamethrin for 28-days. Significant changes were induced by the deltamethrin on the haematological parameters of C. gariepinus fish after 28 days exposure. We observed a concentration and exposure duration (time) dependent alterations in fish exposed to deltamethrin compared with control. Also, the red blood cells, haemoglobin and haematrocrit count, mean corpuscular volume, mean cell haemoglobin concentration, lymphocytes, platelets and white blood cells decreased significantly in deltamethrin exposure concentrations compared with control. Blood parameters showed a time-dependent decreased across exposure groups and concentrations. Results presented herein indicates a concentration and time-dependent alterations in hematological profile of C. gariepinus suggesting a negative physiological effects of deltamethrin on the hematological status of fish.
