Abstract: The nutritional components in the muscle of hybrid oriental river prawn “Taihu No.1”cultured in coastal saline-alkaline pond was determined by biochemical component measurement method and compared to that in the muscle of wild oriental river prawn to explore its  nutritional characteristics . The results showed that the protein, lipid, ash and moisture contents in the muscle of hybrid oriental river prawn were 16.774%, 0.927%, 1.173%, 81.367% respectively. 18 kinds of amino acids(the content was 85.680%, dry weight) were detected in its muscle, in which the total content of the 8 kinds of essential amino acids was 31.024%;  the other 12 kinds were fatty acids the highest in which was the EPA＋DHA accounting for1.247%, and 1.753% of poly-unsaturated fatty acids,; The muscle was abundant with mineral elements. The content of K reached 12.420mg/g, the highest among macroelements, and the content of Zn reached 59.673µg/g, the highest among microelements. The research showed that the protein content in muscle of “Taihu No.1”was significantly lower than that in muscle of wild oriental river prawn(P＜0.05), the fat and EPA＋DHA content were extremely significantly higher than that in muscle of wild oriental river prawn(P＜0.01). the total amino acid, non-essential amino acid and total delicious amino acid between “Taihu No.1”and wild oriental river prawn(P＞0.05) had no significant differences, and the total content of essential amino acid was significantly lower than that in muscle of wild oriental river prawn(P＜0.05), but the compositions of essential amino acid of the both prawns met the WHO/FAO standards. It was indicated that hybrid oriental river prawn “Taihu No.1”cultured in coastal saline-alkaline pond consists of well-balanced amino acid with abundance microelements, which has high nutritional value. .

摘要： 为研究杂交青虾“太湖1号”在滨海型盐碱水域养殖条件下的营养特点，采用常规生化成分测定法测定了该杂交青虾肌肉中的营养成分，并与野生青虾的肌肉营养成分进行比较。结果显示，杂交青虾肌肉（鲜重）中蛋白质、脂肪、灰分、水分的含量分别为16.774%、0.927%、1.173%、81.367%；肌肉中共检测出18种氨基酸（总量为85.680%，干重），其中8种必需氨基酸占31.024%；肌肉中含12种脂肪酸，其中二十碳五烯酸（EPA）与二十二碳六烯酸（DHA）含量较高，二者含量之和为1.247%，多不饱和脂肪酸（PUFA）含量为1.753%；矿物元素种类丰富，常量元素中，钾含量最高（12.420 mg/g），微量元素中，锌含量最高（59.673 µg/g）。研究发现，杂交青虾“太湖1号”蛋白含量显著低于野生青虾（P＜0.05），脂肪、EPA＋DHA含量极显著高于野生青虾（P＜0.01），氨基酸总量、非必需氨基酸总量、鲜味氨基酸总量与野生青虾无显著差异（P＞0.05），必需氨基酸总量显著低于野生青虾（P＜0.05），但二者氨基酸结构均符合FAO/WHO的标准要求。研究表明，滨海型盐碱水域养殖条件下的杂交青虾“太湖1号”氨基酸组成平衡，微量元素丰富，具有较高的营养价值。
