| 中文摘要: |
| 分析了饥饿和冉投喂处理后红鲫（Carassius auratus red variety）幼鱼的生长和体组分变化。饥饿状态下，红鲫幼鱼体重、比肝重、肥满度和肝体指数下降，各饥饿组体重均与同期对照组存在极显著差异（P〈0．01），其中饥饿15d组体重与初始体重存在极显著差异（P〈0．01），肝糖原、粗蛋白和粗脂肪含量下降，水分和灰分含量上升；再投喂后，除饥饿15d组肝糖原与对照组仍有极显著差异外，其他各项指标均恢复到与对照组无显著差异。实验过程中，各饥饿组食物转化率均明显高于对照组，且与对照组存在极显著差异（P〈0．01），其中饥饿10d组最高，达到了24．38％。结果表明，红鲫幼鱼存在完全补偿生长能力，其完全补偿生长是通过提高食物转化率（FCE）来实现的，短期饥饿时将糖原和粗脂肪作为主要能源物质。

| 英文摘要: |
| The changes of growth and body biochemical composition was examined after different starvation and refeeding treatment in juvenile Carassius auratus red variety. The index of weight, hepatosomatic, CF, HIS declined under state of starvation. The weight of all starvation groups had very notable difference compared with that of the same term comparison group（ P 〈 0.0l ）. The weight of starvation-15-days-group had very notable difference com- pared with the initial weight（P 〈 0. 01 ）. The content of liver glycogen, protein and lipid declined when the content of moisture and ash raised after starvation. All of the index had recovered to have no notable difference with the comparison group after re-feeding except the content of liver glycogen of starvation-15-days-group. In this experiment, all starvation groups had very notable difference compared with that of the same term comparison group （P 〈 0.01 ）. The results indicated that the fish displayed completely compensatory growth and it was achieved by impro- ving feed conversion rate （ FCE% ）. The fish made glycogen and lipid as major energy substance when it faced short period starvation. |
