Technical Bulletin No. 0111: Progress Report on Dissolved Oxygen Tolerance of Bluegills at 25 and 35 Degrees Centigrade

The dissolved oxygen tolerance of fish species common to the southern region of the country at summer temperature levels was the subject of this investigation. In the experiments reported, the ultimate lower dissolved oxygen limits and temperature at which bluegills would survive, when other environmental factors were maintained at levels designed to place a minimum of stress on the physiology of the fish, were determined.
