摘要

Acute toxicity test was carried out with aqueous extract of?Datura innoxia?leaf on?Clarias gariepinus?fingerlings for?96 h under laboratory conditions using static bioassays with continuous aeration. The LC50?of the exposed fingerlings was?120.23 mg/L with lower and upper confidence limits of 96.18 and 150.29 mg/L, respectively.?The fish exhibited loss of balance, respiratory distress, vertical and erratic movement, accumulation of mucus on the body surface and gill filament and death.?Water quality parameters were within recommended acceptable limits.
