摘 要：
[目的]研究商城肥鲵的含肉率及其肌肉生化成分,为商城肥鲵营养生理生态研究提供基础资料。[方法]用生化分析方法测定了商城肥鲵的含肉率及其肌肉生化成分。[结果]商城肥鲵的含肉率雌性为54.93%、雄性为55.84%,肌肉含蛋白质雌性为15.44%、雄性为15.67%,总糖雌性为1.70%、雄性为1.89%,脂肪雌性为0.68%、雄性为0.53%。商城肥鲵肌肉中18种氨基酸总量为12.72%(鲜重),其中8种必需氨基酸量为4.68%;必需氨基酸指数(EAAI)为72.68,限制性氨基酸为缬氨酸。商城肥鲵肌肉中包含11类脂肪酸,不饱和脂肪酸含量(80.02%)远大于饱和脂肪酸含量(19.98%)。[结论]商城肥鲵属于低脂肪高蛋白的营养类型,是一种可贵的野生自然资源。

摘 要：
[Objective]The ratio of flesh content and biochemical compositions in muscles of Pachyhynobius shangchengensis were researched in this experiment to provide basic referrences for studying nutritive physiological ecology of Pachyhynobius shangchengensis.[Method]The biochemical analytic method was used to detect the ratio of flesh content and biochemical compositions in muscle of Pachyhynobius shangchengensis.[Result]The ratio of flesh contents of female and male Pachyhynobius shangchengensis were 54.93% and 55.84% respectively.The contents of protein,total saccharides and fatty acid of female Pachyhynobius shangchengensis were 15.44%,1.70% and 0.68% respectively,while the same contents of male Pachyhynobius shangchengensis were 15.67%,1.89% and 0.53% respectively.The total content of 18 kinds of amino acids was 12.72%(the proportion in fresh weight),among which the content of 8 kinds of essential amino acids was 4.68%.The essential amino acids index(EAAI) was 72.68 and limiting amino acids was valine.There were 11 kinds of fatty acids in muscles of Pachyhynobius shangchengensis,among which the content of unsaturated fatty acids(80.02%) was higher than that of saturated fatty acids(19.98%).[Conclusion] Pachyhynobius shangchengensis was a kind of valuable natural resource belonging to the nutritious type of low fat content and high protein content.
