ABSTRACT

Clarias gariepinus with mean weight 6.86g +0.34 obtained from a homogenous source through induced breeding were exposed to different concentrations of Sunsate^® for 96hours using static bioassays with continuous aeration under laboratory conditions to determine the acute toxicity of glyphosate in Sunsate^® on the fish. LC₅₀ of the exposed fingerlings were found to be 17.5 mg l^-1. The fish showed toxicosis symptoms such as loss of balance, respiratory distress, vertical and erratic movement, accumulation of mucus on the body surface and death. Result on blood glucose response shows that as the concentration increases so the blood glucose, therefor precautious use of Sunsate^®in the control of aquatic weed is advised.
