Copper-based control: zebra mussel settlement and nontarget impacts

Project manager: Jim Luoma  

Funded by: Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources

Description: This project will develop population-level management techniques to reduce the impacts of zebra mussels. The treatments are designed to target the early life stages of zebra mussels and prevent successful settlement. The project includes three main objectives:

  • Evaluate the efficacy of low-dose copper treatments to control zebra mussel populations by  targeted suppression of the early life stages
  • Evaluate the impacts that low-dose copper treatments have on algal biomass and native zooplankton, benthic invertebrates, fish, and mussels
  • Provide transferable results by collecting the input parameters required for EPA’s Biotic Ligand Model for copper toxicity

Once complete, these treatments may be useful for population level management or eradication in small water bodies.

Project start date: 2018

Estimated project end date: 2020
