Abstract: In order to compare the fatty acid composition in muscle of Mastacembelus armatus between farmed and wild populations, by gas chromatography analysis of cultured and wild fish, Mastacembelus armatus at juvenile ,fingerling and adult stage ,the muscle fatty acid composition and relative content were detected. The results showed that the muscle of cultured and wild Mastacembelus armatus had 24 kinds of fatty acids, the content of unsaturated fatty acid were the highest, the average content respectively (65.63 + 1.88)% and (59.03 + 2.11)%, especially rich in C18:2, docosahexaenoic acid(DHA) eicosapntemacnioc acid(EPA) and arachidonic acid(AA) polyunsaturated fatty acids; ΣUFA/ΣSFA ratio from juvenile to adult stage was on the rise, and the cultured population (2.45 + 0.21) higher than that of wild populations (1.98 + 0.15); the ratio of P/S to 1 for breeding Mastacembelus armatus at adult stage, more than half of the freshwater fish. Comprehensive analysis showed that the fatty acid content in muscle at different growth stages of farmed and wild Mastacembelus armatus although had some differences,also the breeding Mastacembelus armatus Sadvantage over wild Mastacembelus armatus but the meat quality in breeding Mastacembelus armatus fatty acid composition and equilibrium Similar to wild Mastacembelus armatus .
