Exploring changes in nutrient transfer within Great Lakes food webs: implications for fish production in Lake Michigan in support of CSMI 2010

Dates

Start Date
2010
End Date
2013

Summary

Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, sport fish, and their diets to complement the seasonal lower trophic level sampling by EPA. This data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build a decision support tool that can explore how different scenarios (dreissenid control, nutrient reductions, changes in fish stocking) influence the biomass of economically important fisheries.
