| 研究秀丽高原鳅肌肉营养成分和评价肌肉营养价值，为其开发利用与人工养殖提供参考依据，为开展相关配合饲料研究积累资料。2013年12月从云南省鹤庆县龙潭采集秀丽高原鳅野生个体，随机抽取30尾成鱼作为实验用鱼，体长(8.00±1.16 )cm、体重(6.27±3.19) g。用常规方法测定分析了30尾秀丽高原鳅肌肉的营养成分组成与含量，并对其营养价值进行了综合评价。结果显示，秀丽高原鳅肌肉中水分、粗蛋白质、粗脂肪和粗灰分的含量分别为70.92%、22.10 %、3.73 %和1.25%；共检测出18种氨基酸，氨基酸总量为13.64%；包括8种人体必需氨基酸和10种非必需氨基酸，所占比例分别为5.98%与7.66%；第一限制性氨基酸为色氨酸，必需氨基酸指数为48.11；鲜味氨基酸占氨基酸总量的30.94%。主要含有16种脂肪酸，其中多不饱和脂肪酸含量为32.11%，EPA与DHA总含量为11.68%；常量元素中磷的含量最高（786.60 10-2mg/g)，微量元素中Mg的含量最高 (14.75 10-2mg/g)。秀丽高原鳅营养成分丰富均衡、味道鲜美，具有较高的食用价值与保健作用。因此，秀丽高原鳅肌肉也具有一定的保健肝脏作用。表明秀丽高原鳅肉味比较鲜美。秀丽高原鳅肌肉脂肪酸中PUFA及EPA和DHA总量均较高，表明秀丽高原鳅是一种健康的膳食鱼，对人体具有良好的保健作用。 |

| Triplophysa venusta is a small to medium-size fish species, belonging to Triplophysa, Cobitidae and Cypriniformes and primarily distributed in the Yanggongjiang of Jinsha River basin. In this study, the nutritional components and nutritive quality in the muscle of T. venusta was tested and analyzed using routine methods to provide reference for the artificial culture of T.venusta and generate data for a related study of compound feed. Wild T.venusta specimens were collected from Heqing County, Yunnan Province. The muscle tissue of thirty individuals with average body length of (8.00±1.16) cm and body weight of (6.27±3.19)g was sampled and analyzed for moisture, crude protein, crude fat, crude ash, macro and trace elements, amino acids and fatty acids. Moisture, crude protein, crude fat and crude ash of fresh muscle tissue were 70.92%, 24.10 %, 3.73 % and 1.25%, respectively. Eighteen amino acids were detected in the muscle, accounting for 13.64% of the muscle, including 8 essential amino acids (5.98%) and 10 non-essential amino acids (7.66%). The essential amino acids index (EAAI) was 48.11 and tryptophan (TRP) was the least abundant. In dry samples, the content of delicious amino acids was 30.94% of the total amino acid content. Sixteen fatty acids were detected, 6 saturated fatty acids, 3 monounsaturated fatty acids and 7 polyunsaturated fatty acids, accounting for, respectively, (35.79±0.13)%, (29.87±0.06)% and (32.11±0.14)% of the total fatty acid content. The content of EPA and DHA was 11.68%, higher than in some other fish species. The trace elements, essential for metabolism, growth and development, were abundant. The phosphorus (P) content was the highest among the macro elements (7.87±0.40 mg/g) and the magnesium (Mg) content was the highest (0.148±0.02 mg/g) among the trace elements. This research indicates that T.venusta has high nutritional value and good taste, is highly edible and healthy. |
