The fatty acid composition of N. crepidularia collected frommangroves of Vellar estuary (Lat. N 11º 29.45ÂÂ’ Long. 79º 46.28ÂÂ’), Southeast coast of India was determined. In the present study, 13 different fatty acids were identified, seven were saturated (SFA), four were monounsaturated (MUFA) and two were polyunsaturated fatty acids (PUFA). Among the SFAs pentadecyclic acid (C15:0) and palmitic acid (C16:0)were themajor acids. In MUFA octadecenoic acid (C18:1n-7) and in PUFA Arachidonic acid (C20:4ù6C) were the major acids found. The percentage of SFA, MUFA and PUFA was reported as 58.05%, 28.82% and 8.28% respectively in N. crepidularia. Hence in the present study notify potential position of this gastropod in the field of aquaculture and human nutrition.
