Deep-water shrimps are non-conventional culinary delicacies due to the presence of essential nutrients, although they are predominantly unexplored marine fishery resources. The nutritional composition of deep-water shrimp species Aristeus alcocki, Heterocarpus chani, Plesionika quasigrandis, Solenocera choprai, and Metapenaeopsis andamanensis captured from Arabian Sea (southwest coast of peninsular India) was determined. The shrimp demonstrated a well-composed essential/non-essential amino acids ratio (0.76-0.84). Among other deep-water shrimps, protein content, total aromatic, and sulfur-enclosing amino acids were substantially higher in A. alcocki (12.69 g 100 g-1, 344 and 270 mg 100 g-1 wet tissue, respectively). The C20-22n-3 polyunsaturated fatty acid analogues (docosahexaenoic and eicosapentaenoic acid) were found to be in appreciable quantities (82-130 and 56-120 mg 100 g-1 wet edible portion, respectively) in the studied deep-water shrimp species. Lower thrombogenicity and atherogenicity indices (0.16-0.32 and 0.35-0.53, respectively) acknowledged the studied deep-water shrimp species as valuable health food items for cardioprotection and anti-platelet aggregation.
