Abstract: Adult Nile Tiapia, Oreochromis niloticus was exposed to Jatropha curcas seed powder, a multipurpose plant used for demarcation, boundaries and the seeds for biodiesel and traditional medication. The histological alteration of the gill, skin and liver were studied at sub-lethal concentration of 133.3,200, 266.7, 333.3, 400 and 0 as control. The pathological lesions observed on the gill are Lamella degeneration, Hyperthrophy of the gill arc and severe necrosis of gill filament, Submucosal Congestion, Severe erosion of the secondary lamellae and cartilage at the base. The lesions on the skin are necrosis, dermal cell erosion and cellular infiltration by mononuclear cells. In the liver, moderate degeneration of periportal, diffuse vacuolation of hepatocytes and congested portal area were observed. The alteration on each of the organ became severe with increase in concentration of Jatropha curcas seed powder.
