The impact of atrazine herbicide on juveniles of Clarias ganiepirus was evaluated using standard methods. The experiment was set up in a completely randomized design (CRD) using plastic aquarium tanks with five species of C. gariepinus in four treatments (including a control) and three replicates; a total of sixty (60). Laboratory conditions with a natural photoperiod (12 h light – 12 h dark) were set up at the College of Natural Resources and Environmental Management (CNREM), Michael Okpara University of Agriculture,
