| Abstract: | ![]()
The activity levels of lactate dehydrogenase andlactic acid were assessed in various tissues of the fishduring exposure to lethal concentration of group-IIPyrethroids (deltamethrin, cypermethrin, fenvalerate andfluvalinate) for a period of 72 hours. The results showedsteady increased levels in all the tissues (blood,muscle, brain and liver) with response patterncharacteristic of their own. The increased LDH activityand lactic acid levels indicate the shifting of aerobicglycolysis to anaerobiosis and its further utilizationfor energy production during adaptation to toxic stress. |
