Comparative Studies on the Chemical Composition of Inland Saline Reared Litopenaeus vannamei

ABSTRACT

A comparative study of chemical composition between the muscles of Litopenaeus vannamei reared in inland saline water (ISRV) and brackish water (BWRV) was taken up. Slightly higher water content, pH, nonprotein nitrogen fractions were observed in ISRV. Some amino acids like glutamic acid, aspartic acid, arginine, lysine and glycine contents were higher in BWRV. On the contrary, ISRV meat had higher hydroxyproline, alanine and leucine content. The polyunsaturated fatty acid content of BWRV and ISRV samples were 41.67% and 46.50%, respectively. Potassium was the dominant mineral in both BWRV and ISRV shrimp meats, i.e., 1011 and 836.3 mg/100 g of meat, respectively. The proportion of composition varied with both the shrimp sample. Though the composition was varied most of the amino acids, fatty acids and minerals were comparable to one another. Therefore, it can be concluded that the overall meat quality of ISRV shrimp is not affected.
