Acid-base balance and ionic regulation during emersion in the estuarine intertidal crab Chasmagnathus granulata dana (Decapoda Grapsidae)
Haemolymphatic P(O2), P(CO2), and pH, and ionic concentrations of haemolymph and branchial chamber water were measured in submerged and emersed crabs. Hypercapnia and respiratory acidosis were recorded after 15 min of air exposure, then P(CO2) remained constant and pH was compensated. Sodium concent...

Sodium concentration increased in haemolymph and decreased in branchial water. The difference between haemolymph Naa+ and Cl- increased dramatically. Acid-base balance is restored by two mechanisms: a) increase of the P(CO2) gradient across the gills and consequently the rate of CO2 excretion; b) the increase in the strong ion difference, caused by branchial sodium uptake, compensates the hypercapnic acidosis. |
