EFFECT OF NAPHTHALENE ON PHOSPHATASES AND ESTERASE 1N MUSCLE AND OVARY OF INTERMOULT MARINE EDIBLE FEMALE CRAB, SCYLLA SERRATA

摘要

The effects of naphthalene on glycogen, lipid, phosphatases and esterase have been studied in the muscle and ovary of intermoult marine female crab, Scylla serrata. Rearing the crab in increasing sublethal concentrations of naphthalene for 96 hr (i.e. 0.005, 0.0l0, 0.0l5 and 0.020 mg L~-1). The results show an overall decrease in the glycogen, lipid, alkaline phosphatase and esterase in muscle and ovary. On the other hand, acid phosphatase activity in the muscle and ovary has increased.
