Abstract:
A quantitative study was made on the occurrence of cholesterol in the muscle of different maturity stages of the wilder tiger shrimp Penaeus monodon collected from Pazhayar coast, Nagapattinam, Tamil Nadu. As the size increased from 8-10 cm to 14-16 cm the cholesterol content increased from 1.4-4.5 mg g-1. The shrimp contained almost the same level of cholesterol in both sexes. The variation in the cholesterol level in relation to moulting in the male and female shrimp revealed that in both the sexes high cholesterol content was noticed in the intermoult stage. Subsequently, in the premoult stage the cholesterol content decreased from 2.0-1.8 mg g-1 and it was found to be the lowest among all the moult stages. In the matured stages the shrimp contained higher level of cholesterol (2.1 mg g-1) and very less amount of cholesterol level (1.2 mg g-1) in the immature and early mature stages. It is inferred from this study that the cholesterol level was more in the intermoult stage suggesting that cholesterol may be converted to some moulting hormones.
