| 摘要: |
| 在高密度室内饲养条件下, 观察了脊尾白虾(Exopalaemon carinicauda)的摄食、相残、运动、蜕皮、间隔、攻击和防御行为。试验结果表明, 脊尾白虾摄食行为活跃, 运动行为多样, 在饥饿或个体较大差异条件下具有一定程度的相残行为, 蜕皮行为表现出一定的特殊性, 常经数天多次蜕皮行为特征后才能将旧壳蜕下, 间隔行为不明显, 攻击频率不高。另外, 通过设置不同投喂组和投喂间隔时间观察比较了索饵率和相残率, 结果表明, 索饵率在第8 小时已基本达到最高, 相残率随投喂间隔时间的延长和空间密度的增大而升高。 |

| Abstract: |
| This study described the behaviors of feeding, cannibalism, locomotion, molting, spacing, attacking and defence of Exopalaemon carinicauda cultured in high-density farming system. The results revealed that feeding behavior was active; locomotion behavior was diversiform; cannibalism behavior was obviously related to both of starvation and variability of the shrimp body size and the rate of cannibalism would increase with the increase of time separation of feeding and the increase of rearing density; the molting behavior was special, which occurred several times during a molting process; and spacing behavior was not obviously and the frequency of attacking was low. |
