In order to evaluate the seasonal changes in nutritivevalue of ribbon fish, in relation to size, total lipidand fatty acid profiles of different sizes of ribbonfish, Lepturacanthus savala captured in differentseasons were studied. Total lipid content wassignificantly (p<0.05) high in large sized ribbon fishcaptured during winter and lowest in medium sizegroups during post-monsoon season. A total of 37fatty acids were identified by Gas Chromatography- Mass Spectrometry encompassing saturated, monounsaturated, n-6, n-3 poly unsaturated and odd andbranched chain fatty acids. The highest content ofeicosapentaenoic acid (9.42%) and docosahexaenoicacid (33.16%) were found in the post-monsoonseason. The high levels of n-3 PUFA (12.37 – 43.14%)and favourable n-3/n-6 PUFA ratio of 1.79 to 5.04revealed nutritional significance of ribbon fish inhuman diet. The difference between small, mediumand large groups of ribbon fishes of the respectiveseason based on fatty acid composition was clearlyestablished by principal component analysis.
