Dogfish were exposed to sudden changes of Pco2 in inspired seawater. During hypercapnia breathing frequency remained constant, but gill ventilation was transiently increased to about 140% of control levels in the 1st h. O2 uptake was significantly increased also, but returned to the initial level before nomalization of gill ventilation. In contrast to the transient rise in gill ventilation and O2 uptake, arterial Po2 was increased for the whole period of hypercapnia. Hypercapnia results in a… CONTINUE READING
