Chlorpyrifos (CPF) and Cypermethrin (CPM) are two toxicants, commonly used in agriculture field to control the insecticidal activity throughout the world. The usages of this toxicant, it affects the aquatic system. The present study has been to examine the enzymatic activates of two toxicants in muscle tissues of mud crab (Scylla serrata). The crabs were introduced in these toxicants for 24 hrs in laboratory conditions to analyze the enzyme activities of ALP, SDH andLDH in the muscle of mud crab. ALP and SDH declined in Chlorpyrifos showed mean value 3.88 ± 0.29 μg/ PNPP to PNP/100 mg and 8.42±0.62 MIU/min/mg than the cypermethrin (3.02±0.38μg/ PNPP to PNP/100 mg and 7.89±0.51 MIU/min/mg) and control(9.38 ± 0.58MIU/min/mg and 4.01±0.49 μg/ PNPP to PNP/100 mg). LDH elevated in both the group particularly in Chlorpyrifos (9.01 ± 1.32 μg/100mg) than control (7.98±0.62μg/100mg), therefore Chlorpyrifos showed maximum impact on muscle tissues of mud crab than cypermethrin.
