［目的］为了对长臀鮠(Cranoglanis bouderius) 的肌肉营养价值做出综合评判，对该种鱼的营养需要量的制定和计算提供依据，［方法］利用常规肌肉营养测试方法测定分析了长臀鮠的肌肉营养成分。［结果］长臀鮠肌肉(鲜样)中粗蛋白质量分数17.86％，粗脂肪质量分数14.27％，水分质量分数65.70％，灰分质量分数2.06％，碳水化合物质量分数0.11％。肌肉中含有18种氨基酸，总量为68.71％，其中8种人体必需氨基酸总量是26.84％，占氨基酸总量的39.06％；4种鲜味氨基酸总质量分数为26.66％；肌肉中含有16种脂肪酸，其中EPA与DHA质量分数分别为1.86%和2.85%。［结论］表明长臀鮠是营养价值较高，提供高能，肉味鲜美的高品质淡水鱼类。

Abstract: 【Objective】【Method】Nutritional components in the muscle of Cranoglanis bouderius were tested and analyzed with routine methods. Samples of 10 wild—cultured individuals were collected from Tibet selincuo lake in January of 2007.【Result】The results showed that contents of crude protein，crude fat，moisture，ash and carbohydrates of fresh muscles were 17.86％,14.27％,65.70％,2.06％ and 0.11％respectively．The composition of amino acids of muscle was 18 common amino acids and 8 essential amino acids for human needs. In dry sample the total content of amino acids was68.71％; the content of essential amino acids was 26.84％.the percent age of essential amino acids in total amino acids were 39.06％, In dry sample the content of four kinds delicious amino acids was 26.66％. The composition of fatty acids of muscle was 16 fatty acids The contents of EPA and DHA in fatty acids were 1.86％and 2.85％,which were higher than some other economic fishes.【Conclusion】It was indicated that Cranoglanis bouderius is one of freshwater fishes with better nutritive value and raising value, deserving exploitation and utilization.
