Toxicity of dizensate (Glyphosate herbicide) on Clarias gariepinus fingerlings

Run-off containing a number of chemical solutions, which include herbicides, effluents, find their ways into the water bodies with a resultant negative effects on the aquatic ecosystem. This study sought to establish the effects of herbicide widely used in eradicating aquatic weed; Dizensate glyphosate (N- phosphonomethyl glycine) on Fingerlings of African catfish (Clarias gariepinus). The four day static bioassay was used to determine the median lethal concentration (LC50) and the value was ...
