摘　　要：在水温(23.0±1.0)℃条件下,以鲜杂鱼(x)和配合饲料(p)为饵料,采用室内循环流水的试验方法研究饥饿后再投喂对牙鲆幼鱼补偿生长、生化组成及能量收支模式的影响。结果表明:试验组S1F5、S5F25均表现出完全补偿生长现象,且S1F5组主要通过提高摄食率(FR)来实现补偿生长,而S5F25组主要通过提高食物转化率(FCE)来实现补偿生长;经补偿生长后,各试验组鱼体的生化组成与对照组均无显著差异(P>0.05);经饥饿处理后牙鲆幼鱼生长能占摄食能的比例增加,用于排泄和代谢的比重有所下降。By using indoor re-circulating system,this paper studied the compensatory growth,biochemical composition,and energy budget of juvenile Japanese flounder（Paralichthys olivaceus） starved for various days and re-fed with trash fish and formulated diets at 23.0±1.0 ℃.The experimental groups S1F5 and S5F25 all had complete compensatory growth.The compensatory growth of group S1F5 was primarily attributed to the increase of feeding rate,while that of S5F25 was heavily dependent on the improvement of food conversion efficiency.After compensatory growth,there were no significant differences in the biochemical composition of the fish between treated groups and the control（P0.05）.Under starvation,the proportion of energy intake for growth tended to increase,while the proportion of energy for excretion and metabolism energy tended to decrease.
