Comparison Of Bigheaded Carp Reproduction In Tributaries Of The Illinois And Wabash Rivers, David J. Yff
Comparison Of Bigheaded Carp Reproduction In Tributaries Of The Illinois And Wabash Rivers, David J. Yff
Masters Theses
Understanding environmental conditions that support bigheaded carp (Hypophthalmichthys sp.) reproduction in tributary rivers provides key predictions of their invasion throughout the United States. Past research, primarily in larger order rivers, identified factors such as discharge, temperature, and turbidity as main environmental drivers of bigheaded carp reproduction. I used the variable hydrologic conditions between the Illinois and Wabash Rivers to compare environmental conditions between tributaries of each basin, determine which conditions influence bigheaded carp reproduction in tributaries, and predict tributaries likely to support bigheaded carp reproduction. Three tributaries of the Illinois and Wabash Rivers were sampled for ichthyoplankton from …
Differences In The Growth And Bioenergetics Between Centrarchids In A Midwestern Power Plant Lake, Kyle Joseph Rempe
Differences In The Growth And Bioenergetics Between Centrarchids In A Midwestern Power Plant Lake, Kyle Joseph Rempe

Black Crappie Pomoxis nigromaculatus and Bluegill Lepomis macrochirus are popular sportfishes that co-occur in similar bodies of water throughout most of the Central and Eastern United States but have distinct thermal physiologies. L. macrochirus is often found in warmer regions of freshwater reservoirs, where P. nigromaculatus tends to exploit cooler regions, especially in power plant cooling reservoirs. The coal-fired Coffeen Power Station ceased energy production in October 2019, providing an ideal scenario to study the organismal effects of the sudden shift in thermal regime. Previous studies showed that P. nigromaculatus inhabited the less thermally-impacted areas of Coffeen Lake, whereas L. …
