Carp (Cyprinus carpio) were exposed to environmental water pH (pHw) step changes from 7.4 to 5.1, 5.1 to 4.0 and 4.0 to 3.5 pH, PCO2, PO2 and lactate in dorsal aortic blood, [Na+], [K+] and [Cl-] in dorsal aortic plasma, base loss, and ammonia excretion were determined as a function of time after ea...
