title: [Carbon dioxide fixation in aquatic animals and its metabolic significance].
abstract: In experiments on the carp Cyprinus carpio and freshwater lamellibranch mollusc Anodonta cygnea, tissue and organ peculiarities of carboxylic reactions have been revealed together with their relationship to the temperatute and ionic composition of the incubation medium. It was shown that in fish the highest intensity of fixation of CO2 is exhibited by glandular organs with biosynthetic profile of the metabolism (liver), whereas in molluscs it is exhibited in the mantle which plays the key role in the formation of the shell, containing carbonate compounds of calcium.
