Summary

Tench exposed to hypoxia-hypercapnia rapidly develops a large, predominantly respiratory, extracellular acidosis, which is only slowly (t1/2∼47 h) compensated by increased plasma [HCO − 3 ]. The changes in plasma [HCO − 3 ] are stoichiometrically balanced by changes in plasma chloride concentration.

Erythrocytic pH, in contrast to extracellular pH, decreases only transiently, is rapidly restored to control values, and then even increases above the value in normoxia. The changes in erythrocytic acid-base status appear to be correlated with swelling of the erythrocytes, reduced erythrocytic GTP content, and changes in extracellular pH.
