Heuer, J H; Seawell, W M

The responses of fish (smallmouth bass, channel catfish, golden shiners, and bluegill), zooplankton, and benthic macroinvertebrates to various levels of dissolved oxygen (DO) were monitored in six large outdoor channels at TVA's Aquatic Research Laboratory at Browns Ferry Nuclear Plant. Nitrogen stripping was used to remove oxygen from the water, and aquatic organisms were exposed to target levels of 5, 4, 3, and 2 mg/L (2 channels) and to an untreated control from July 24, 1984 until September 24, 1984. Responses of adult golden shiners, bluegill, and channel catfish to DO were not consistent, probably because of predation by smallmouth bass on golden shiners and competition between bluegill and channel catfish. Bluegill spawned successfully only in the control. Cleaned nests were found in the 5 mg/L treatment and partially cleaned nests in the 3 and 4 mg/L treatments, but no evidence of nesting was found in the 2 mg/L treatment. 14 refs., 8 figs., 7 tabs.
