| 摘 要： | 分别测定1、5、10、20、45日龄黄姑鱼仔稚鱼中的氨基酸、游离氨基酸、脂肪酸组成。结果表明黄姑鱼仔稚鱼的氨基酸组型和游离氨基酸组型是不断变化的。必需氨基酸中的精氨酸、缬氨酸、亮氨酸、异亮氨酸、赖氨酸5种氨基酸占必需氨基酸总量的70%左右。非必需氨基酸中的天冬氨酸、谷氨酸和丙氨酸占非必需氨基酸总量的60%左右。随着仔稚鱼的生长,游离氨基酸含量呈显著降低的趋势。1日龄仔鱼的游离氨基酸含量最高,为12.134 g/100 g;45日龄稚鱼的游离氨基酸含量最低,为1.497 g/100 g。黄姑鱼仔稚鱼的主要脂肪酸为:16:0、18:0、16:1、18:1和DHA。各日龄黄姑鱼仔稚鱼体脂肪酸含量差异较大,但仔稚鱼的必需脂肪酸DHA、EPA和ARA始终保持较高的含量。

| Abstract: | The amino acid, free amino acid and fatty acid of the Nibea albiflora larvae during ontogeny were illustrated. The amino acid and free amino acid content of the larvae was varied during ontogenesis. The amount of arginine, valine, leucine, isoleucine, lysine was accounted for about 70% of total essential amino acids. The amount of aspartic acid, glutamic acid and alanine was accounted for about 60% non-essential amino acids. The amount of free amino acids showed a significant decrease during ontogenesis. Fatty acid composition of the feed affected the fatty acid composition and content of the larvae. Docosahexaenoic acid DHA, eicosapentaenoic acid EPA, arachidonic acid ARA, the essential fatty acid of the larvae, was in high level during ontogency. |
