The effects of acute hypoxia and hypercapnia on oxygen consumption of the freshwater European eel
When exposed to hypoxia, eels Anguilla anguilla were able to regulate and maintain VO2 down to a water oxygen tension (PWO2) of about 25 mmHg, a value far below those reported in other studies. When exposed to hypercapnia, eels showed a depression in VO2 as water carbon dioxide tension (PWCO2) incre...
