| 摘 要： | 2005年5~6月,采用岸边定点和流动观察的方法,对生活在半自然夹江水域中的母仔长江江豚(Neophocaena phocaenoides asiaeorientalis)的呼吸行为进行了观察。结果表明,在仔豚出生的第一个月内,母仔豚的呼吸行为有以下主要特征:(1)仔豚出水仰角大于母豚;(2)母豚常背驮仔豚出水呼吸;(3)母仔豚呼吸行为多发生在夹江中心水域。

| Abstract: | Respiratory behavior of the mother and baby Yangtze Finless Porpoise(Neophocaena phocaenoides asiaeorientalis) have been observed in the semi-nature aqueous reserve from May 19 to June 18,2005.The mother and her baby showed three characteristics in the way of breathe when the baby porpoise was less than one month in age:(1) the angle of the baby porpoise's mouth above water is larger than its mothers';(2) the baby porpoise kept close to or lay on its mother's back;(3) the respiratory behaviors usually occur when they are in the middle of water. |
