Abstract
In opposition to current views, Järnefelt (1949) has pointed out that the oxygen content of streams may rise above the saturation value as a result of the action of rapids and falls. Ebeling (1954) and Höll (1955) and others have also observed this phenomenon, but none of these authors have given an explanation of the processes causing the supersaturation. Recently, however, Mortimer (1956 p. 5) seems to have touched upon the truth from a theoretical point of view. Gas supersaturation in streams has repeatedly been observed by fish culturists especially in its deleterious effect on fish life, i. e. the gas bubble disease. It has been studied for some years from the Hölle salmon laboratory on the river Indalsälven in Sweden (Andrén, 1955, Carlsson, 1956), and investigations have also started at Bergeforsen’s salmon rearing station close to the mouth of the same river. These latter seem to have explained at least one cause of oxygen supersaturation in rivers.
