![]() Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These 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 bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

Description of Work In 2011, the US EPA, USGS, and Canada’s DFO/EC continued the evolution of the strategy to conduct an “integrated’ (water quality to fish) spatially-consistent assessment for the entire lake in order to provide biomass estimates for each trophic level. A total of 54 sites were sampled during summer 2011. Water chemistry, nutrients, phytoplankton, zooplankton, benthic invertebrates, Mysis, and pelagic and benthic fish were collected at each site.

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.
