Technical Bulletin No. 0123: The Influence of Carbon Dioxide and pH on the Dissolved Oxygen Requirements of Some Fresh Water Fish

The belief has been held by many aquatic biologists that the carbon dioxide tensions of waters could not only have a direct effect on fish life, but could interfere seriously with their gas exchange functions, having a definite effect upon the dissolved oxygen concentration necessary for their survival. Technical Bulletin No. 123, attached hereto, reports on research in respect to the effect of carbon dioxide and pH on the dissolved oxygen requirements of fresh water fish.
