| 摘 要： | 1998年4月28日—6月24日和5月20日—7月14日分别在汕头大学南澳海洋生物实验站研究了杂交罗非鱼停喂(简称绝食)或限量投喂(简称限食)后的补偿生长，探讨了杂交罗非鱼补偿生长的生物能量学机制。结果表明，海水养殖杂交罗非鱼在饱食状态下的能量收支为100C=32.8G+50.8R+15.3F+1.1U。在恢复生长期间，对照鱼的食物能和代谢能高于绝食鱼或限食鱼，但其单位体重的食物能、代谢能、生长能、粪能和排泄能均明显低于补偿生长的绝食鱼或限食鱼，绝食或限食后海水养殖杂交罗非鱼的能量收支模式未发生明显变化。

| Abstract: | Compensatory growth of hybrid tilapia (Oreochromis niloticus × O.aureus) reared in seawater,following a period of feed deprivation or ration restriction,were studied at Nan'ao Marine Biology Station,Shantou,China,between April and July,1997,respectively. Bioenergetic mechanism of hybrid tilapia in relation to compensatory growth is discussed in this paper. Energy budget of excessively fed hybrid tilapia can be expressed as 100C=32.8G+50.8R+15.3F+1.1U. During the recovery period,energy intake and metabolism energy are higher in the control fish than those in the deprived or restricted fish. However,the ratio of energy intake,metabolism energy, growth energy,fecal energy,and excretion energy,to body weight at the start of the recovery period are lower in the control fish than those in the deprived or restricted fish which exhibited compensatory growth. There are no significant differences in energy budget between the control fish and the deprived or restricted fish. |
