摘　　要：在水温（29．2±0．2）℃条件下，研究了饥饿和再投饲对点带石斑鱼幼鱼脂肪酸和氨基酸的影响？结果表明：随着饥饿时间的延长，饱和脂肪酸和单不饱和脂肪酸下降，但多不饱和脂肪酸上升（P〈0．05），氨基酸总量和必需氮基酸总量显著下降，与对照组差异显著（P〈0．05）。说明饥饿胁迫后产生了饥饿效应；恢复投饲后，实验组鱼体内的脂肪和能量百分含量与对照组不再存在显著差异。各实验组的氨基酸总量和必需基酸均显著高于对照组（P〈0．05）。结合体重变化为判断指标，饥饿2d的点带石斑鱼幼鱼具有完全补偿生长的能力，饥饿4～10d具有部分补偿生长的能力；以氨基酸为指标，饥饿2～10d的点带石斑鱼幼鱼均具有完全补偿生长的能力。The effects of starvation and re-feeding on amino acid and fatty acid composition in the juvenile of Epinephelus malabaricus were studied at （29.2 ±0.2） ℃. With the extension of starvation time, the results showed that the saturation fatty acid （SFA） and mono-unstauration fatty acid （MUFA）were significantly decreased （ P 〈 0.05 ）, the poly unsaturation （PUFA） was increased significantly （ P 〈 0.05 ）. Compared with the control group , the gross of the amino acid and the essential amino acid both dropped significantly （P 〈0.05）,which stressed that after starvation the effects of the starvation occrured; After re-feeding, compared with the control group, the experimental group of fish in the percentage of fat and energy no longer existed significant differences, the total of the amino acid and the essential amino acid were both higher than that （P 〈 0.05 ）. Combined with the weight changes for the judgment of indicators, after 2 days starvation, the juvenile of Epinephelus malabaricus were with full compensation for the growth capacity, but after 4 - 10 days starvation, the juvenile of Epinephelus malabaricus were only with part of the growth capacity. For amino acids as an indicator, after 4 - 10 days starvation, the juvenile of Epinephelus malabarieus were all with full compensation for the growth capacity.
