Pesticides affect non-target organisms, the ecosystem including the atmosphere, soil, groundwater, surface water and the food web. This study was undertaken to investigate mancozeb toxicity on the Clarias gariepinus juveniles’ kidney, liver and spleen histoarchitecture. A total of 120 C. gariepinus with standard length and weight that ranged from 9.8 to 17.5 cm and 11 to 55 g were used for the experiment. Catfish juveniles were exposed to four sub-lethal concentrations (treatments) viz: 0.00, 20.55, 41.09 and 82.18 mg/L (Groups A-D) mancozeb fungicide. Each group was replicated three times and had 10 fish per replica summing up to 30 fish. The kidney of C. gariepinus exposed to lower concentrations showed vacuolar degeneration and necrosis of tubule lining cells, while the control group showed normal piscine kidney histoarchitecture...
