摘要
通过１年多的观察证明，大鲵在人工养殖条件下，水温对其摄食具有显著的影响。观察结果表明，大鲵冬眠的复苏温度为８５℃±１５℃，春季摄食高峰期的温度为２３２℃±２０℃，夏季停止摄食的起始温度为２７８℃±１８℃，夏季复苏温度为２４７℃±１２℃，秋季摄食高峰期温度为１８０℃±１６℃，开始冬眠的温度为１１５℃±１６℃。
Observation of more than one year show that the intake of andrias davidianus is significantly affected by water temperature.Results shown that the temperature of recovery of andrias davidianus from no intake period in winter is 8 5 ℃±1 5℃ the temperature of highest intake period in spring is 23 2℃±2 0℃ the start temperature of no intake period in summer is 27.8℃±1.8℃,the temperature of recovery in summer is 24 7℃±1 2℃ the temperature of highest intake period in autumn is 18 0℃±1 6℃ the start temperature of no intake period is 11 5℃±1 6℃
