N1 - Funding Information:
CDS received the grant. Agreement #G19AC00069 Funding from the United States Geological Survey Cooperative Ecosystem Studies Units. http://www.cesu.psu.edu/default.htm USGS personnel helped with study design and data collection, but personnel from the University of Illinois were responsible for analyses, the decision to publish and manuscript preparation. CDS was also supported by the University of Illinois, Urbana-Champaign and the USDA National Institute of Food and Agriculture Hatch Project (grant number ILLU-875-940) https://urldefense.com/v3/__ https://nifa.usda.gov/program/hatch-act-1887multistate-research-fund__;!!DZ3fjg! rWA6OMKHRxGdyETmb35RN4 GqQxoFWXG8HWjtZ_YHSU1HvHBp6JB-X6SG rMtyg_2f$ and this funding body did not play any role in the research. Special thanks to; Jim Duncker of United States Geological Survey his support of the research and assistance in collecting fish from Rock Run Rookery and, the Illinois Natural History Survey who collected the fish from Havana and, Illinois Department of Natural Resources who collected the fish from Starved Rock.

N2 - Bigheaded Carp have spread throughout the Mississippi River basin since the 1970s. Little has stopped the spread as carp have the ability to pass through locks and dams, and they are currently approaching the Great Lakes. However, the location of the leading edge in the Illinois River has stalled for over a decade, even though there is no barrier preventing further advancement towards the Great Lakes. Defining why carp are not moving towards the Great Lakes is important for predicting why they might advance in the future. The aim of this study was to test the hypothesis that anthropogenic contaminants in the Illinois River may be playing a role in preventing further upstream movement of Bigheaded Carp. Ninety three livers were collected from carp at several locations between May and October of 2018. Liver samples were analyzed using gas chromatography-mass spectrometry in a targeted metabolite profiling approach. Livers from carp at the leading edge had differences in energy use and metabolism, and suppression of protective mechanisms relative to downstream fish; differences were consistent across time. This body of work provides evidence that water quality is linked to carp movement in the Illinois River. As water quality in this region continues to improve, consideration of this impact on carp spread is essential to protect the Great Lakes.
