摘　　要： 饥饿处理黑鲷 (Sparusmacrocephalus) 2、 5、 10、 15和 30d ,分别测定血清生长激素 (GH)和甲状腺激素三碘甲状腺原氨酸 (T3 )浓度以及脂肪和蛋白质在白肌和肝脏中的含量 ;同时测量正常摄食动物的相应指标作为对照。数据分析结果显示 :①饥饿 15d后血清GH水平显著升高 ,T3 水平显著降低 ;②饥饿 15d后白肌蛋白质含量显著降低 ,而脂肪含量则在饥饿 2d就降低 ,并维持此低水平 ;③肝脏脂肪含量在饥饿 10d后显著升高 ,而蛋白质呈不规则波动。GH水平升高能强化储能物质的转化 ,而T3 水平降低可降低代谢水平。 The contents of growth hormone (GH) and triiodothyronine (T 3) in serum,and protein and lipid in white muscles were measured for black seabreams ( Sparus macrocephalus ) in starvation for 2,5,10,15 and 30 days as treatments.At the same time the measurements were also made for the animals under normal condition as control.Testing for the difference between the treatment and control resulted in:①the level of serum GH significantly increased after 15 day starvation,and that of T 3 decresed;②the content of protein in white muscles decresed after 15 day starvation,and the reduction of lipid occurred after 2?d and kept the low level to the end;③the content of lipid in livers increased significantly after 10?d,and that of protein fluctuated irregularly.The increase of serum GH could ehance the translation of body materials into engery,and the reduction of T 3 would reduce the metabolic rate,which could be viewed as physilological responses for the species to adapt the stress of starvation.
