中文摘要：

一个 60 天的喂实验被进行调查饮食的 omega-3 的影响生长，营养的作文和水兵的有免疫力的功能上的丰满的酸(n-3 LC-PUFA ) 捞的长链的多元不堡和 Sebastiscus marmoratus。包含 3.6， 10.2， 18.2， 26.5，或 37.0 的五本食谱 g/kg n-3 LC-PUFA 被准备。结果在最后的重量上揭示饮食的 n-3 LC-PUFA 的重要影响，重量获得，特定的生长评价，喂变换比率，并且调节因素。作为增加的饮食的 n-3 LCPUFA，重量获得和增加并且在组是显著地更高的特定的生长率喂了 18.2， 26.5 和 37.0 g/kg 比在组喂了 3.6 和 10.2 g/kg (P < 0.05 ) ；喂的组之间没有重要差别 18.2， 26.5，或 37.0 g/kg (P > 0.05 ) 。与增加饮食的 n-3 LC-PUFA，在肌肉和肝的 eicosapentaenoic 酸和 docosahexenoic 酸内容显著地增加了，逐渐地从 9.1 ～ 14.8 g/L 增加的免疫球蛋白班 M 内容，和溶解酵素活动内容从 1 355 ～ 2 268 U/mL 增加了。破线模型分析根据重量，获得显示 18.2 g/kg 的饮食的 n-3 LC-PUFA 水平为在 125 g/kg 的胖水平的正常生长是必要的。因此，拨出饮食的 n-3 LC-PUFA 不仅支持生长并且改进 n-3 LC-PUFA 内容，而且在 S 提高有免疫力的功能。marmoratus。

英文摘要：

Abstract A 60-day feeding experiment was conducted to investigate the influence of dietary omega-3 long-chain polyunsaturated fatty acids （n-3 LC-PUFA） on growth, nutritional composition and immune function of marine fish Sebastiscus marmoratus. Five diets containing 3.6, 10.2, 18.2, 26.5, or 37.0 g/kg n-3 LC-PUFA were prepared. The results reveal significant influences of dietary n-3 LC-PUFA on the final weight, weight gain, specific growth rate, feed conversion ratio, and condition factor. As dietary n-3 LC- PUFA increased, weight gain and specific growth rate increased and were significantly higher in groups fed 18.2, 26.5 and 37.0 g/kgthan in groups fed 3.6 and 10.2 g/kg （P〈0.05）; there was no significant difference between groups fed 18.2, 26.5, or 37.0 g/kg （P〉0.05）. With increasing dietary n-3 LC-PUFA, eicosapentaenoic acid and docosahexenoic acid content in muscle and liver increased significantly, immunoglobulin class M content gradually increased from 9.1 to 14.8 Ixg/L, and lysozyme activity content increased from 1 355 to 2 268 U/mL. Broken line model analysis according to weight gain indicated that a dietary n-3 LC-PUFA level of 18.2 g/kg is essential for normal growth at a fat level of 125 g/kg. Therefore, appropriate dietary n-3 LC-PUFA not only promote growth and improve the n-3 LC-PUFA content, but also enhance immune function in S. marmoratus.
