The indiscriminate use of plant extracts as anti-microbial agent on culturable fish (catfishes and the Cichlids) in confinement is alarming, especially the use of neem leave extracts. Neem (Azadirachta indica) is a medicinal plant containing active biological and chemical properties. The effects of aqueous Azadirachta indica (neem) extract on the cytology and genome composition of hundred post juvenile Oreochromisniloticus with mean length and weight of 9.37±0.67cm and 8.99±1.84 g respectively was investigated in a tank culture system to determine the median lethal concentration (LC50) at 96 h of exposure. Five graded concentrations of 1.2, 1.4, 1.6, 1.8 and 2.0 L of the aqueous extract and control were diluted in 15 L of water in triplicate. The control group and group exposed to 1.2 L concentration of neem extract showed normal behaviour while group exposed to 1.6 and 1.8 L concentrations showed abnormal behavioural changes such as rolling movement, gulping of air, weakness, swimming on the back and eventually death was observed. There was significant difference (p<0.05) in the toxicity effects of neem extract at 14th and 28th day of exposure. Cytotoxic effect was evident by cellular apoptosis which increases with increase concentration of the extract while genotoxic effect was manifested by formation of nuclear aberrations within the erythrocytes. The results obtained in this study revealed that neem extract has clastogenic and apoptotic effects on the erythrocytes of Oreochromis niloticus.
