The present study was designed to evaluate the 96 hours LC₅₀of Sunsate® and the hematological variation of fingerlings of African catfish exposed to different concentrations of the herbicides. Using static bioassays with continuous aeration under laboratory conditions acute toxicity of Sunsate^® was determine to be 18.33 mg l^-1with upper and lower limit of 20.93 and 16.05 respectively. Also the toxicant led to significant (P<0.05) changes in haematological parameters as the toxicant concentration increased. Haemoglobin content (Hb), Mean Red Blood Cells (RBC), Platelet count (PLT), Packed Cell Volume (PCV), reduced as the concentration of toxicant increased while other parameters increased proportional with the toxicant concentration. Precautious use of Sunsate^® for the control of Aquatic weeds is recommended.
