人工饲养条件下白鱀豚的行为节律

RHYTHMIC BEHAVIOUR OF LIPOTES IN CAPTIVITY

  • 摘要: 1985年4月至1986年3月观察了饲养6年的雄性白鱀豚“淇淇”的十种宏观行为,即顺时针方向游、逆时针方向游、仰游、侧游、转游、直立、玩、性行为、捕食和休息。行为型式变换次数的统计表明,白鱀豚存在明显的食前节律和昼夜节律。另外,顺时针方向游发生在夜间为多,逆时针方向游白天发生的多。以上2种行为所占的总时间大致相等。典型的休息行为均发生在夜间,全年在1月和5—8月出现2个高峰期。4—5月和8—9月出现2个性行为高峰。转游在早晨和白天摄食后共出现1个高峰期,而且与饲养池条件有关。呼吸行为的昼夜节律不明显。

     

    Abstract: Ten behavioural patterns——clockwise swimming, counterclockwise swimming, swimming on back and side, rolling, upright positioning, playing, sexual behaviour, fish catching and resting——were observed during April 1985-March 1986 from a male Lipotes in captivity for over six years. The statistics of variation in the behavioural patterns indicated that there were obviouscircadian rhythms and seasonal rhythms. The clockwise swimming often occurred at night, and the counterclockwise swimming usually took place in the daytime. The total duration for either type of swimming in the course of 24 hours was nearly equal.The typical resting behaviour occurred at night, with peaks in January and May-August. There were obvious peaks of sexual behaviour during April-May and August-September. Rolling swimming occurred in the morning and after feeding during the day, and had three peaks, correlated to the condition of the dolphin pool. The circadian respiratory rhythm was not evident.
