dc.description.abstractThe differential acute toxicity of aqueous and ethanolic extracts of Ipomoea aquatica leaf on Nile Tilapia, Oreochromis niloticus were carried out under laboratory conditions. The LC50 after 96hr of exposure for aqueous and ethanolic extracts of Ipomoea aquatica were 2.659g/L and 0.196g/L respectively. These values showed that ethanolic extract of Ipomoea aquatica was more toxic than its aqueous extract. Signs of agitated behaviours, respiratory distress and abnormal nervous behaviors including eventual deaths were observed in exposed fish. Control fish neither died nor exhibited any unusual behaviour. The randomized analysis of variance (ANOVA) showed that there were significant differences (P<0.05) in the quantal response (mortality) of O. niloticus to aqueous and ethanolic extracts of I. aquatica at 24hrs, 48hrs, 72hrs and 96hrs of exposure period. It was investigated that leaf of Ipomoea aquatica has piscicidal property and can be put into use in the control and management of fish ponds to eradicate predators by farmers.en_US
