Abstract : This study was to assess the effects of deltamethrin on some haematological parameters of Heteropneustes fossilis (Bloch). For 4 days, 30 Heteropneustes fossilis were exposed to two different concentrations of Deltamethrin which were 20% (0.91 ìg·L-1) and 40% (1.88 ìg·L-1) respectively. The results obtained from this study showed that the White Blood Cell (WBC), Haemoglobin content (Hb), Hematocrit percentage (PCV), Mean Corpuscular Volume (MCV) and Mean Corpuscular Hemoglobin (MCH) were decreased in treated groups when compared to the control (p<0.05). However, the number of Red Blood Cell (RBC) increased in deltamethrin treated fish (p<0.05). Mean Corpuscular Hemoglobin Concentration (MCHC) values were insignificant when compared to control group (p>0.05).
