中华鳖幼体呼吸代谢的初步研究
Preliminary Study of Respiration Metabolism in The Soft-Shelled Turtle (Trionyx sinensis)
-
摘要: 本文利用改装后的Kalabukhov-Skvortsov呼吸器,同时测定了中华鳖在自由潜水状态下的空气呼 吸和水呼吸摄氧量。结果表明:在正常生活状态下,中华鳖主要依靠空气呼吸摄氧;水呼吸仅占总呼吸摄氧量的2.68%左右。呼吸摄氧率无显著昼夜变化。Abstract: Aquatic and aerial respiration in freely-diving soft-shelled turtle Trionyx sinensis were measured with refited Kalabukhov-Skvortsov respirometer.The results showed that,the soft-shelled turtle depended mainly on aerial respiration,aquatic oxygen consumption was only 2.68% of total oxygen consumption.No significant difference in oxygen consumption was measured at day and night.
