Abstract:

Short-term definitive test by static renewal bioassay method was conducted to determine the acute toxicity (LC50) of commercial grade synthetic insecticide, cypermethrin (25% EC) and its impact on oxygen consumption in a freshwater edible fish, Cyprinus carpio. Fingerlings were exposed to lethal (3.31 μg/L) and sublethal (0.331 μg/L) concentrations of cypermethrin for 96h. In sub-lethal concentration, experimental fish Cyprinus carpio showed an increased tendency in oxygen consumption during the initial time of exposures i.e. 2 to 4 hours and a gradual decrease during the subsequent study period. Fish showed gradual decrease in oxygen consumption from the starting period of exposure to till the end of the experiment in lethal concentration. Alterations in oxygen consumption may be due to respiratory distress as a consequence of impaired oxidative metabolism.
