| 摘 要： | 在饥饿状态下,测量了瓦氏黄颡鱼的肝指数、性腺指数变化,并对消化管的形态变化进行了描述。结果表明：随着饥饿时间的延长,瓦氏黄颡鱼的肠管收缩,变细,成透明状;肠内的皱褶减少,变浅,胃囊扁平,胃壁变薄。在饥饿0、5、10、15、20d后,肝指数分别为：0.0323、0.0279、0.0187、0.0134和0.0114。肝指数随着饥饿时间的延长而减小,饥饿对其影响差异极显著（P〈0.01）;性腺指数的变化不显著（P〉0.05）。

| Abstract: | Hepatic somatic indices（HSI） and gonad indices（GI）of Pelteobagrus vachelli were measured under the condition of starvation,and the change of the alimentary canal also be described during the same time.The results showed ： with the increasing starvation days,alimentary canal shrunked,turned small and got transparency;intestinal fold reduced and became simple,stomach became flat and thin.HSI were 0.0323,0.0279,0.0187,0.0134 and 0.0114,respectively after fasted 0,5,10,15 and 20d.The effect of starvation on HSI was significantly but not on GI. |
