| 墨脱四须鲃肉味鲜美、营养丰富，是雅鲁藏布江下游较大型鱼类。参照国标用常规方法分析墨脱四须鲃肌肉，结果发现：肌肉中粗蛋白含量占18.6%，粗脂肪占0.65%，水分占79.1%，灰分占1.4%；检测出16种氨基酸，其氨基酸评分(AAS)77.142，化学评分(CS)47.368，氨基酸指数(EAAI)86.157，第一限制氨基酸为甲硫氨酸（Met）+半胱氨酸（Cys），氨基酸支/芳值（BCAA/AAA）2.434。检测出22种脂肪酸，必需脂肪酸占脂肪酸总量的38.4%，其致动脉粥样硬化指数（IA）及血栓形成指数（IT）值分别为0.352和0.230。因此，墨脱四须鲃的肌肉是一种极佳的蛋白质及脂肪源，墨脱四须鲃具有养殖及推广的潜力。 |

| Abstract: |
| Barbodes hexagonlepis is a kind of delicious, nutritional and large fishes in the lower reaches of the Yarlung Zangbu River. Analysis of the muscle of the B.hexagonlepis with conventional methods was carried out, and the results showed that: it contains crude 18.6 % protein, 0.65 % crude fat, 79.1 % moisture and 1.4 % ash. Its muscles contain 16 amino acids, the amino acid score(AAS) was 77.142, chemical score (CS)was 47.368, the essential amino acid index( EAAI) was 86.157, and the first limited amino acid was Met+Cys; amino acid branch/aromatic value（BCAA/AAA) was 2.434. Its muscles contain 22 fatty acids. Essential fatty acids accounted for 38.4 % of the total fatty acids, moreover，index of atherogenicity（IA）and index of thrombogenicity（IT） were 0.359 and 0.230, respectively. Therefore, the muscle of B.hexagonlepis is a good source of protein and fat, and the fish has the potential to be cultivated and developed. |
