对平均体重为 1.2 2g、2 6 5g和 10 94g的一龄、二龄和三龄养殖鲈鱼肌肉中的水分、蛋白质、脂肪及氨基酸和脂肪酸含量进行了分析 .结果表明 ,养殖鲈鱼肌肉中水分、蛋白质和脂肪的含量分别为76 .39%～ 77.5 1%、17.6 8%～ 18.12 %和 3.5 6 %～ 4 .0 3% .鲈鱼肌肉的氨基酸总量占肌肉干重百分比在一龄、二龄和三龄养殖鲈鱼中分别为 76 .6 2 %、75 .11%和 73.78% ,平均为 75 .17% ,必需氨基酸分别为 4 0 .10 %、39.0 2 %和 36 .6 9% ,平均为 38.6 0 % .每克肌肉 (湿重 )含有脂肪酸总量在一龄、二龄和三龄养殖鲈鱼中分别为 2 2 .10mg、2 0 .6 5mg和 13.4 2mg ,平均为 18.72mg ,其中PUFA总量分别为10 .19mg、7.5 7mg和 2 .5 4mg ,平均为 6 .77mg .
The contents of water, protein, fat, amino acids and fatty acids in the pericarp muscle of the first, second and third instar cultured sea bass with mean body weights of 1.2 2g, 2 6 5g and 10 94g were analyzed.The results showed that the water, The contents of protein and fat were 76.39% -77.51%, 17.68% -18.12% and 3.56% -4.33%, respectively.The total amino acid content of muscle of perch muscle was in the first and second instar Respectively, 76.62%, 75.1 1% and 73.78%, respectively, with an average of 75.17% and essential amino acids of 40.10%, 39.0% and 36.69%, respectively. The average Was 38.6% .The total amount of fatty acids contained per gram of muscle (wet weight) was 22.01 mg, 20.65 mg and 13.4 mg, respectively, in an average of 18.72 mg in the first-, second-, and third- The total PUFAs were 10.19 mg, 7.57 mg and 2.54 mg, respectively, with an average of 6.77 mg.
