Browns Ferry Biothermal Research Series. II. Effects of Temperature on Bluegill and Walleye, and Periphyton, Macroinvertebrate, and Zooplankton Communities in Experimental Ecosystems

摘要

Effects of long-term, March-September 1977, temperature elevations on aquatic communities in 12 outdoor experimental channels were evaluated. Macroinvertebrates, periphyton, and zooplankton colonized the channels naturally from the water supplied from Wheeler Reservoir, Tennessee River. The fish community consisted of stocked adult bluegill and juvenile walleye. Four temperature regimens, with three replicate channels per regimen, were maintained. The major objective of the study is to provide information for establishing temperature criteria for protection of important sport and commercial fish species.
