Abstract
In order to evaluate the seasonal changes in nutritive
value of ribbon fish, in relation to size, total lipid
and fatty acid profiles of different sizes of ribbon
fish, Lepturacanthus savala captured in different
seasons were studied. Total lipid content was
significantly (p<0.05) high in large sized ribbon fish
captured during winter and lowest in medium size
groups during post-monsoon season. A total of 37
fatty acids were identified by Gas Chromatography
- Mass Spectrometry encompassing saturated, mono
unsaturated, n-6, n-3 poly unsaturated and odd and
branched chain fatty acids. The highest content of
eicosapentaenoic acid (9.42%) and docosahexaenoic
acid (33.16%) were found in the post-monsoon
season. The high levels of n-3 PUFA (12.37 – 43.14%)
and favourable n-3/n-6 PUFA ratio of 1.79 to 5.04
revealed nutritional significance of ribbon fish in
human diet. The difference between small, medium
and large groups of ribbon fishes of the respective
season based on fatty acid composition was clearly
established by principal component analysis.
