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。
Under the condition of water temperature (23.0 ± 1.0) ℃, freshwater fish (x) and compound feed (p) were used as bait. The experiment of indoor circulating water was used to study the effect of starvation on the compensatory growth, biochemical composition And energy revenue and expenditure model. The results showed that S1F5 and S5F25 all showed complete compensatory growth in experimental group, and compensatory growth was mainly achieved by increasing food intake rate (FR) in S1F5 group, while compensatory growth was mainly achieved by increasing FCE in S5F25 group. After compensation for growth, the biochemical composition of fish in each experimental group had no significant difference compared with the control group (P> 0.05). After the starvation, the ratio of growth energy to food energy of juvenile flounder increased, the proportion for excretion and metabolism was The decline.
