采用室内生态实验法研究了军曹鱼(Rachycentron canadum)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100.00A=49.32G+50.68R.
The indoor compensatory growth pattern of juvenile Coals (Rachycentron canadum) (initial body weight (17.43 ± 0.85) g, starvation 0 (control group) The results showed that the energy and weight loss rate of juvenile fish increased significantly with the prolongation of starvation time. The average daily food intake (energy index) of juvenile fish in the starvation group was higher than that of the starvation-treated fish In the control group, the average daily feeding rate of juvenile fish fed starvation for 8d was the highest (17.20%). The energy, wet weight and specific growth rate of dry weight of juvenile fish increased with the prolongation of starvation time ; Cobia juveniles achieved their full compensatory growth ability by increasing the feeding rate during the process of post-starvation restoration. The energy budget equation for juvenile cobia juveniles was 100.00C = 38.33G + 15.06F + 7.22U + 39.39R, the assimilation energy allocation is 100.00A = 49.32G + 50.68R.
