Abstract: The aim of this study was to explore the fatty acids (FAs) composition of Indian loach freshwater fish (Botia lohachata and Botia geto) and compare the existing levels of essential fatty acids. The fatty acid composition was evaluated by Gas chromatography–Mass spectrometry (GC-MS). Fatty acid methyl esters (FAMEs) were identified comparing their retention time with the commercial analytical standard mixtures FAME Mix, C4-C24. The fatty acids profiles include odd-number, branched-chain, and even-number fatty acids as well as saturated components, the monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). The major Saturated fatty acids SFAs were C14:0, C16:0 and C18:0. The C18:1n-9c was the prominent MUFAs. The essential fatty acid compositions showed prominence in C18:3n-3 and C18:2n-6. The branched chain fatty acids identified were C15:0, C16:0, C17:0, C18:2 and C20:0. The results of the study has shown that Botia lohachata is a good source of MUFAs while Botia geto is a good source of ω-6 EFAs and the high percent of branched and saturated FAs.
