摘要： 为比较人工养殖大刺鳅与野生大刺鳅肌肉脂肪酸组成的差异,采用气相色谱分析法对养殖和野生大刺鳅幼鱼、鱼种、成鱼肌肉脂肪酸组成及其相对含量进行了检测与分析。结果表明,养殖和野生大刺鳅肌肉中共检出24种脂肪酸,其中不饱和脂肪酸含量较均最高,平均含量分别达到(65.63±1.88)%和(59.03±2.11)%,特别是含有丰富的C18:2、二十二碳六烯酸、二十碳五烯酸和 ,花生四烯酸等多不饱和脂肪酸；ΣUFA/ΣSFA比值从幼鱼到成鱼阶段显上升趋势,且养殖大刺鳅(2.45±0.21)高于野生大刺鳅(1.98±0.15)；养殖大刺鳅成鱼阶段的P/S比值达到1.0,超过一般的淡水鱼类。综合分析表明,养殖大刺鳅肌肉品质在脂肪酸组成及均衡性略优于野生大刺鳅,但差异不明显。

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 .
