Biochemical Constituents of Shrimps from Semi-Intensive and Modified-Extensive Culture Ponds

A quantitative study on the occurrence of major biochemical constituents including protein, carbohydrate, lipid and cholesterol in the muscle of different growth stages of Penaeus monodon collected from semi-intensive (SI) and modified-extensive (ME) culture ponds of coastal Andhra Pradesh, adopting different feeding schedule was undertaken. The objective was to determine the effects of the age of shrimp and the stocking density on the biochemical composition of the muscle. Protein was found to be the major biochemical constituent and an increase in protein content with advancement of shrimp age was recorded. Glycogen occurred only in traces. Lipid and cholesterol occurred in moderate quantities with concentrations slightly higher in shrimps of SI ponds as compared to those ME ponds. Overall, the stocking density had little impact on protein and glycogen concentration in the muscle.
