| 为了解日本新糠虾成体的营养组成及其与饵料营养组成的关系,本研究采用养殖实验和生化分析方法,测定和比较了日本新糠虾雌雄成体及其饲料的常规营养成分、脂类、脂肪酸和氨基酸含量。结果显示：(1)饲料中的粗蛋白和粗脂肪分别为40.48%和9.82%,高度不饱和脂肪酸(HUFA) 含量和DHA/EPA比值分别为27%和1.34,总氨基酸(TAA)和10种必需氨基酸(EAA)含量分别为38.80%和16.32%。(2) 雄、雌成体的水分含量均在88%左右,雌体的粗蛋白、粗脂肪和甘油三酯含量均显著高于雄体,雄体的磷脂含量显著高于雌体。(3) 除14:0和16:1n-7外,雌雄成体的饱和脂肪酸和单不饱和脂肪酸组成接近,雄体的ARA、EPA、DHA、∑HUFA和DHA/EPA显著高于雌体,雌体的LOA、LNA和18:4n-3含量高于雄体；雌体的异亮氨酸、亮氨酸、苯丙氨酸、苏氨酸、精氨酸、半胱氨酸、天冬氨酸、丝氨酸和谷氨酸含量显著高于雄体,雄体牛磺酸的含量显著高于雌体,雌体的EAA和TAA总量显著高于雄体。(4) 雌体的LOA和LNA的相对保留率高于雄体,而雄体的ARA、EPA和DHA相对保留率高于雌体；雌雄成体对各EAA的相对保留率接近。综上,日本新糠虾成体具有高蛋白、高HUFA、高EAA、低脂肪和低碳水化合物的特征,故具有较高的营养价值；雌雄亲本的营养组成差异可能暗示其营养需求有所不同。 |

| Nutritional composition and gender defferences of adult mysis are important for the evaluation of nutritional value and the understanding of broodstock nutrition requirement for Neomysis japonica. In order to compare the nutritional composition between the males and females of adult mysis N. japonica under the feeding formulated diets, this study was conducted to detect and compare the the proximate composition, lipid classes, fatty acid and amino acid compositon between the adult males and females as well as the formualted diet by the culture experiments and biochemical analysis. Independent T-test was usded to examine the differences between males and females, while P <0.05 was regareded as statistically significant differences. Moreover, the relative retention ratios (animal tissue contents/dietary contents) were further analyzed on the poly-unsaturated fatty acids (PUFA) and essential amino acids (EAA) for both males and females. The results showed that, (1) The crude protein and crude lipid of the formualted diet were 40.48% and 9.82% respectively, while the content of high unsaturated fatty acid (HUFA) and DHA/EPA ratio were 27% and 1.34, respectively (Table 1). The contents of total amino acids (TAA) and ten essential amino acids (EAA) were 38.80% and 16.32% respectively (Table 1). (2) The mositure content of males and females was around 88%, and no gender difference was found for them (Table 2). However, the adult females had the significantly higher contents of crude protein, crude lipid and triglyceride than the adult males, while the males had the higher phospholipid levels than the females (Table 2). (3) Except for 14:0 and 16:1n-7, the adult males and females had the similar compositions for the saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) (Table 3). The adult males had the higher percentage of ARA, EPA, DHA, ∑HUFA and the DHA/EPA ratio than the adult females, while the females had the higher LOA, LNA and 18:4n-3 levels than the males (Table 3). As for the amino acids, the females had the higher contents of EAA, TAA, isoleucine, leucine, phenylalanine, threonine, arginine, cysteine, aspartic acid, serine and glutamate than the males, while the adult males had the significantly higher taurine levels than the females (Table 3). (4) The adult females had the higher relative retention ratio of LOA and LNA and the lower relative retention ratio for ARA, EPA and DHA than the adult males, but the relative retention ratios of EAA were close between the adult males and the females (Table 4). In conclusion, adult N. japonica had the gender differences on the levels of crude protein, crude lipids, triglyceride, phospholipids, some fatty acids, some amino acids and the relative retention ratios of some fatty acids between adult males and females, which may indicated adult females and males had the different nutritional requirement. |
