Effects of glyphosate-based herbicide on gametes fertilization and four developmental stages in Clarias .

Comparative toxicology continues to provide information on how the age of every living organism affects the frequency, severity, and nature of the potentially toxic agent. We investigated the effect of glyphosate-based herbicide (GBH) exposure on gametes and four developmental stages of Clarius gariepinus (C) (African Catfish). Gametes from healthy gravid female and mature male C were exposed to GBH in sublethal concentrations of 0.
