中文摘要：
为探讨哲罗鱼稚鱼的最佳投喂策略，设置了饥饿再投喂试验、饥饿再投喂恢复试验以及日投喂频率试验．结果表明：饥饿再投喂试验中，各饥饿组未表现出补偿生长现象．但在饥饿再投喂恢复试验中，各饥饿组表现出不同程度的补偿生长，其中S1/2组（饥饿1／2d投喂1／2d）体质量的增加量与对照组接近，表现出完全补偿生长．表明在哲罗鱼早期稚鱼阶段（体质量0～2g，水温9～15．3℃），S1／2是可以考虑使用的投喂方法．日投喂频率试验中，T3组（日投喂3次）体长、体质量的增加量以及特定生长率均最高，饵料转化率也相对较高．表明在哲罗鱼后期稚鱼阶段（体质量2～21g，水温8．8～15．5℃），以日投喂3次为宜．
英文摘要：
Three experiments including starvation and re-feeding, starvation and re-feeding recovery, and feeding frequency per day were conducted to approach the optimal feeding strategy for the growth and survival of juvenile Hucho taimen. In the experiment of starvation and re-feeding, all groups of restricted feeding showed non-compensatory growth. However, in the experiment of starvation and re-feeding recovery, different degrees of compensatory growth appeared in different starving groups, among which, the half a day starvation and half a day feeding group （ S1/2 ） had a weight increment approximately the same as the control, and showed completely compensatory growth, indicating that the S1/2 could be a useful feeding strategy for the juvenile H. taimen at its early growth stage with the body mass from 0 to 2 g and at the water temperature from 9 to 15.3 ℃. In feeding frequency experiment, the group T3 （three meals per day） had the highest body length, body mass, specific growth rate, and relatively high food conversion ratio, indicating that three meals a day could be more effective for improving the growth performance of juvenile H. taimen at its late stage with the body mass from 2 to 21 g and at the water temperature from 8.8 to 15.5 ℃.
