中文摘要:
      采用定时定点观察法,对仿生态条件下养殖的中国大鲵(Andrias davidianus)活动节律及繁殖行为进行了观察。结果表明,大鲵活动具有明显的昼夜节律变化,白天隐藏在洞穴中不活动,每天20:30时部分大鲵开始出洞活动,21:00时至次日凌晨1:00时为活动高峰期,1:00时后部分大鲵开始陆续回到洞穴,3:00时后又全部隐藏在洞穴中;大鲵的夜间活动随季节的变化而发生周期性变化,8~9月出洞活动的大鲵数量达到一年之中的最大值。大鲵尤其是雄鲵在繁殖季节表现出明显多样的繁殖行为:①推沙行为;②求偶行为,包括聚集、露头、巡视、追随、尾阴探究、亲吻、邀请和爬跨8种行为型;③冲凉行为;④护卵行为;⑤婚配行为。
