采用室内生态实验法研究了军曹鱼（Rachycentroncanadum）幼鱼（初始体重（17．43±0．85）g分别饥饿0（对照组），2，4，6，8d后的补偿生长规律，探讨军曹鱼幼鱼补偿生长的生物能量学机制．结果表明：随着饥饿时间的延长，幼鱼的能量及体重损失率显著升高；恢复生长过程中，饥饿处理组幼鱼的平均日摄食率（能量指标）均高于对照组，其中以饥饿8d组幼鱼的平均日摄食率最高（17．20％）；幼鱼在恢复生长过程中的能量、湿重及干重特定生长率均随着饥饿时间的延长而呈上升趋势；军曹鱼幼鱼在饥饿后的恢复生长过程中通过提高摄食率来实现其完全补偿生长能力；军曹鱼幼鱼在饱食条件下的能量收支方程为100．00C＝38．33G＋15．06F＋7．22U＋39．39R，同化能分配式为100．OOA＝49．32G＋50．68R．

The effect of starvation for different days (0,2,4,6 and 8 days) and compensatory growth on energy budget of juvenile cobia (Rachycentron canadum) was estimated by an experimental ecological method. Results in present study indicated that energy content and body weight of juvenile cobia de- creased significantly after starvation, and during the re-feeding period, ingestion rate in energy and specif- ic growth rate in energy, wet weight and dry weight in the deprived fish were higher than those of control fish. Results also indicated that juvenile cobia showed complete compensatory effect in the recovery growth and it was contributed by the increase of ingestion rate. Energy budget of iuveni|e cobia [ed to sa- tiation was 100.00C=38.33G+15.06F+7.22U 100.00A =49.32G+50.68R. + 39.39R, and expression by assimilated energy was
