IMPACT OF ENDOSULFAN (35% EC) AND FENVALERATE (20% EC)ON ACTIVITY OF ACID PHOSPHATASE AND ALKALINEPHOSPHATASE IN A FRESHWATER FISH LABEO ROHITA

K. SUNEETHA AND K. VEERAIAH

Abstract

The freshwater fish Labeo rohita was exposed to endosulfan and fenvalerate a synthetic pyrethroid.The LC50 values determined for endosulfan and fenvalerate at 24hrs were 0.6876 and 0.4749 μgl-1respectively. The fish were exposed to lethal endosulfan 0.6876 and fenvalerate 0.4749 μgl-1 andsublethal concentrations of endosulfan 0.06876 and 0.04749 μgl-1 for 24hrs and 15days and changesin the activity of Acid phosphatase and Alkaline phosphatase were observed. The enzymesshowed a decrease in activity on pesticide exposure.
