Respiratory exchange measurements in a teleost fish, Cyprinus carpio, in normoxic and hypoxic conditions are presented. Oxygen pressure in the dorsal aortic blood in normoxic carp was much lower than that in most of teleosts and elasmobranchs in similar conditions. The most evident physiological adjustment to the hypoxic condition was the increased ventilation due to an increased frequency of operation of the branchial pump. Increased perfusion at the gills played a small role in the physiological adjustments.
本文展示了在常氧和低氧条件下对硬骨鱼鲤鱼进行的呼吸交换测量结果。在常氧条件下，鲤鱼背主动脉血液中的氧分压远低于大多数处于类似条件下的硬骨鱼和软骨鱼。对低氧条件最明显的生理调节是由于鳃泵运作频率增加导致通气增加。鳃部灌注增加在生理调节中作用较小。
