Forecasting Climate Change Induced Effects on Recreational and Commercial Fish Populations in the Great Lakes
Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management and conservation of fish populations, including those of high recreational and commercial value. Scientists from the US Geological Survey (USGS) worked closely with state management agencies and the National Wildlife Federation to complete several objectives that...
Mercury isotopes reveal an ontogenetic shift in habitat use by walleye in lower Green Bay of Lake Michigan
In general, fish residing in rivers differ from fish residing in lakes in their mercury (Hg) isotope ratios. Specifically, fish residing in lakes typically show enriched values for the isotope ratios of δ202Hg (mass-dependent fractionation of isotope 202Hg) and Δ199Hg (mass-independent fractionation of isotope 199Hg) compared with fish...

Under certain conditions, polychlorinated biphenyl (PCB) concentration in individuals of one sex of an adult fish population may exceed that of the other sex by more than a factor of two. This phenomenon, known as the PCB hot spot effect, has been postulated to be contingent upon the following two conditions: (1) presence of a PCB hot spot in...
Madenjian, Charles P.; Dembkowski, Daniel J.; Isermann, Daniel A.; Batterman, Stuart A.; Chernyak, Sergei C.; Cogswell, Stewart F.; Holey, Mark E. Are changes in lower trophic levels limiting prey-fish biomass and production in Lake Michigan?
To improve understanding of how recent changes in lower trophic levels in Lake Michigan could be affecting prey-fish biomass and production, the Lake Michigan Committee (LMC) convened a Lower Trophic Level Task Group and provided several charges that are responded to in this report. First, we compiled a comprehensive summary of lower trophiclevel...
Bunnell, David B.; Carrick, Hunter J.; Madenjian, Charles P.; Rutherford, Edward S.; Vanderploeg, Henry A.; Barbiero, Richard P.; Hinchey-Malloy, Elizabeth; Pothoven, Steven A.; Riseng, Catherine M.; Claramunt, Randall M.; Bootsma, Harvey A.; Elgin, Ashley; Rowe, Mark; Thomas, Sara; Turschak, Benjamin A.; Czesny, Sergiusz J.; Pangle, Kevin; Warner, David M. Temperature regimes, growth, and food consumption for female and male adult walleye in Lake Huron and Lake Erie: a bioenergetics analysis
Bioenergetics modeling was used to assess the relative importance of food availability and water temperature in determining walleye (Sander vitreus) growth. Temperature regimes experienced by both female and male adult walleye in three basins of Lake Huron and in Lake Erie were determined by use of surgically implanted temperature loggers and...
Madenjian, Charles P.; Hayden, Todd A.; Peat, Tyler B.; Vandergoot, Christopher; Fielder, David G.; Gorman, Ann Marie; Pothoven, Steven A.; Dettmers, John M.; Cooke, Steven J.; Zhao, Yingming; Krueger, Charles C. Ratio of mercury concentration to PCB concentration varies with sex of white sucker (Catostomus commersonii)
The whole-fish total mercury (Hg) concentrations were determined in 25 mature female and 26 mature male white suckers (Catostomus commersonii) caught during their spawning run in the Kewaunee River, a tributary to Lake Michigan. The age of each fish was estimated using thin-sectioned otoliths, and total length (TL) and weight were determined for...
Madenjian, Charles P.; Stevens, Andrew L.; Stapanian, Martin A.; Krabbenhoft, David P.; DeWild, John F.; Ogorek, Jacob M.; Edwards, William H.; Ogilvie, Lynn M.; McIntyre, Peter B. Distributions of PCB congeners and homologues in white sucker and coho salmon from Lake Michigan
We tested the hypothesis of the proportion of higher chlorinated biphenyl (PCB) congeners increasing with increasing trophic level by comparing the respective PCB homologue distributions in an omnivore, white sucker (Catostomus commersoni), and a top predator, coho salmon (Oncorhynchus kisutch), from Lake Michigan. Adult females had the same...
Stapanian, Martin A.; Madenjian, Charles P.; Batterman, Stuart A.; Chernyak, Sergei M.; Edwards, William H.; McIntyre, Peter B. Fish Bioenergetics 4.0: An R-based modeling application
Bioenergetics modeling is a widely used tool in fisheries management and research. Although popular, currently available software (i.e., Fish Bioenergetics 3.0) has not been updated in over 20 years and is incompatible with newer operating systems (i.e., 64‐bit). Moreover, since the release of Fish Bioenergetics 3.0 in 1997, the number of...
Deslauriers, David; Chipps, Steven R.; Breck, James E.; Rice, James A.; Madenjian, Charles P. Comment on linking the sex difference in PCB concentrations of fish to release of eggs at spawning: Time to jettison the dogma
For the past 20 years or so, a commonly used explanation in the scientific literature for higher polychlorinated biphenyl (PCB) concentrations in male fish than in female fish has been that females lose a high proportion of their PCB body burden by releasing eggs at spawning time, and therefore the females undergo a substantial decrease in their...
Madenjian, Charles P. Changes in movements of Chinook Salmon between lakes Huron and Michigan after Alewife population collapse
Alewives Alosa pseudoharengus are the preferred food of Chinook Salmon Oncorhynchus tshawytscha in the Laurentian Great Lakes. Alewife populations collapsed in Lake Huron in 2003 but remained comparatively abundant in Lake Michigan. We analyzed capture locations of coded-wire-tagged Chinook Salmon before, during, and after...
Clark, Richard D.; Bence, James R.; Claramunt, Randall M.; Clevenger, John A.; Kornis, Matthew S.; Bronte, Charles R.; Madenjian, Charles P.; Roseman, Edward F. Sex difference in PCB concentrations of a catostomid fish
Unraveling the complexities associated with the relative differences in contaminant concentrations between the sexes of mature fish may provide insights into important behavioral and physiological differences between the sexes of not just fish but higher vertebrates as well. Whole-fish polychlorinated biphenyl (PCB) concentrations were determined...
Madenjian, Charles P.; Stevens, Andrew L.; Stapanian, Martin A.; Batterman, Stuart A.; Chernyak, Sergei M.; Menczer, Jordan E.; McIntyre, Peter B. Feeding ecology of the walleye (Percidae, Sander vitreus), a resurgent piscivore in Lake Huron (Laurentian Great Lakes) after shifts in the prey community
Recovering populations of piscivores can challenge understanding of ecosystem function due to impacts on prey and to potentially altered food webs supporting their production. Stocks of walleye (Percidae, Sander vitreus), an apex predator in the Laurentian Great Lakes, crashed in the mid‐1900s. Management efforts led to recovery by 2009, but...
