摘要： 为探明不同性别大鲵呼吸行为差异，以及呼吸行为对特殊生理阶段的适应，充实大鲵的呼吸行为特征研究，采用红外影像监测系统监测繁殖前期的雌/雄大鲵的呼吸行为，采用水质监测系统监测大鲵繁育池溪流的水温和溶解氧45 d，统计呼吸行为的单次呼吸时长、呼吸间隔、呼吸频次与总呼吸时长等指标，分析繁殖前期大鲵呼吸行为的昼夜节律和变化趋势，以及呼吸行为指标与水温和溶解氧之间的关系。结果显示：繁殖前期雌/雄大鲵夜间较白天单次呼吸时长长，呼吸间隔短，呼吸频次多，总呼吸时长长。雌鲵的单次呼吸时长较雄鲵约短（8.52±7.13）s，呼吸间隔较雄鲵约小（431.74±171.52）s，呼吸频次较雄鲵约多（2.50±1.21）次/h，每小时总呼吸时长较雄鲵约大（46.18±51.17）s。大鲵的单次呼吸时长、呼吸频次、总呼吸时长与水温正相关，与溶解氧负相关；呼吸间隔与水温负相关，与溶解氧正相关。繁殖前期大鲵的呼吸行为有明显的昼夜节律，雌鲵呼吸代谢较雄鲵旺盛，大鲵能够主动调节呼吸行为以适应水温和溶解氧的变化。

Abstract: To explore the differences in respiratory behavior between different genders of Chinese giant salamanders (Andrias davidianus) and the adaptation of breathing behavior to their special physiological stages, and to enrich the research on the breathing behavior characteristics ofA. davidianus, the infrared image monitoring system was used to monitor the breathing behavior of female and maleA. davidianusin the pre-reproductive period, and the water quality monitoring system was used to monitor the water temperature (WT) and dissolved oxygen (DO) in the stream ofA. davidianus’s breeding pool for 45 days. The indicators of breathing behavior such as single breathing duration (SBD), breathing interval (BI), breathing frequency (BF), and total breathing duration (TBD) were counted, and the circadian rhythm and the change trend of breathing behavior in the pre-reproductive period, as well as the relationship between breathing behavior indicators and WT and DO were analyzed. The results showed that in the pre-reproductive period, female and maleA. davidianushad longer SBD at night, shorter BI, more BF, and longer TBD than during the daytime. The SBD of femaleA. davidianuswas about （8.52±7.13）s shorter than that of maleA. davidianus, and its BI was about （431.74±171.52）s smaller than that of maleA. davidianus.Its BF was about （2.50±1.21）times/h more than that of maleA. davidianus, and its TBD over a hour was about （46.18±51.17）s larger than that of maleA. davidianus. The BD, BF and TBD were positively correlated with WT and negatively correlated with DO. BI was negatively correlated with WT and positively correlated with DO. In the pre-reproductive period,A. davidianushad an obvious circadian rhythm, and the respiratory metabolism of femaleA. davidianuswas stronger than that of maleA. davidianus, and they could actively regulate its breathing behavior to accommodate the changes in the water environment.
