ABSTRACT
The piscicidal potential of water-extract mesocarp ofAzadirachta indica (L) was studied in static bioassay experiment with continuous aeration to determine its acute toxicity The mortality rate and opercular ventilation underlaboratory conditions over 96hr exposure were monitored. The 96 hr LC50 was 81.28 mgI-1 while the threshold value was 21.13 mgI-1. The fish exhibited respiratory distress (such as gasping air), loss of appetite, loss of balance and erratic swimming prior to mortality
