| 对丝尾鳠（Ｍｙｓｔｕｓｗｙｃｋｉｏｉｄｅｓ）肌肉的营养成分进行了测定，并对其营养价值作出评价。结果显示，丝尾!含肉率为６８．３９％，肌肉中水分含量为７８．９２％，粗蛋白含量１７．８５％，粗脂肪含量０．８０％，灰分含量２．４３％；肌肉中水解氨基酸总量为１３．００％，含量最高为缬氨酸（Ｖａｌ），占１．２４％，最低为胱氨酸（Ｃｙｓ），占０．４１％；必需氨基酸含量为５．８０％，占氨基酸总量的４４．６２％。依据１９８５年ＦＡＯ／ＷＨＯ推荐的蛋白质模式为评价标准，计算得出学龄前儿童、学龄儿童和成人３种不同人群水平的氨基酸价（ＡＡＳ）分别为１７６．２６、２５５．６９和５１３．８２；第一和第二限制氨基酸都是亮氨酸（Ｌｅｕ）和赖氨酸（Ｌｙｓ）。研究表明，丝尾!是一种高蛋白质、低脂肪、有开发前景的珍稀和优质鱼类。

| 英文摘要: |
| Nutritional components in the muscle of Mystus wyckioides were measured and analyzed. The results showed，The ratio of flesh in the body was 68. 39%，and the average contents of moisture，crude protein，crude fat and minerals in the muscle were 78. 92%，17. 85%，0. 80 % and 2. 43 %，respectively. The amount of hydrolytic amino acids in the total amino acids of the muscle was 13 .00 %，，with the highest for Val(1 .24 %)and the lowest for Gly ( 0. 41%).The content of essential amino acids was 5.80%，equal 44.62% of the total amino acids. According to FAO/WHO recommended standards for the evaluation of protein patterns in 1985，three different levels of pre-school children，school-age children and adult populations in amino acid score(AAS )，calculated and reached 176.26，255.69 and 513.82 respectively，The first and second restrict amino acids are Leu ( a-aminoiso-caproic acid) and Lys. In conclusion，Mystus wyckioides is a fish of the high protein and low fat to be developing.
