Static renewal bioassay test was conducted to determine the toxicity of pyrithroid Cypermethrin (10% EC) insecticide on a freshwater teleost (Labeo rohita). Fishes were exposed to various concentrations of Cypermethrin for 96 h and the per cent mortality was recorded. The LC50 value was found to be 0.06 ppm. Behavioural changes were observed in fish exposed to lethal concentrations exhibiting erratic and darting movements with imbalanced swimming.

Abstract


Static renewal bioassay test was conducted to determine the toxicity of pyrithroid Cypermethrin (10% EC) insecticide on a freshwater teleost (Labeo rohita). Fishes were exposed to various concentrations of Cypermethrin for 96 h and the per cent mortality was recorded. The LC50 value was found to be 0.06 ppm. Behavioural changes were observed in fish exposed to lethal concentrations exhibiting erratic and darting movements with imbalanced swimming.
