Abstract: The enzymes Acetylcholinesterase (AchE) and Lactatedehydrogenase (LDH) are used as biological markers in the present study.? Enzymes are highly sensitive and used to evaluate the biological effects of organophosphate pesticide chlorpyrifos in freshwater mussel Lamellidens marginalis. The test organisms were exposed to sub-lethal concentration (5 ppm) of chlorpyrifos? for 30 days and allowed to recover for seven days.? A distinct reduction of the enzyme AchE (34 + 3.3 U l-1) was found in the treated hepatopancreas. A significant increase in LDH activity in gill, hepatopancreas and muscle was observed.? There was a significant recovery in AchE and LDH? in the different tissues, after seven days recovery period..? Hence, the changes in the enzymes are found as the best biomarkering tool to evaluate the effect of organophosphate pesticide chlorpyrifos on the aquatic biota.

Key words: Biomarker, LDH, Acetylcholinesterase, Chlorpyrifos
