Abstract
The formulation of glyphosate which is composed of Isopropylamine salt (41 % wt ) is widely used as herbicide both in the terrestrial and aquatic environment. In this experiment, the toxicity of this sulfacant Isopropylamine salt of glyphosate herbicide to post juvenile African catfish (Clarias gariepinus) was examined. This experiment was carried out based on the standard Total Residual Chlorine (TRC), 1984 method at 24, 48, 72 and 96 hrs. Gulping of air, restlessness, surface to bottom movement, sudden quick movement and excessive resting at the bottom were abnormal behaviour observed in the exposed fish. Mortality of C. gariepinus increased (P<0.05) with an increase in glyphosate concentration. The results showed that the 96h LC50 value of glyphosate was 300 mg/L while the maximum allowable concentration (MAC) of this toxicant is 30.0 mg/L. The effect of the toxicant on C. gariepinus was both time and concentration dependent”.

Key words: Acute toxicity, Clarias gariepinus, Glyphosate, LC50, Mortality
