International Symposium on
Genetic Biocontrol of Invasive Fish


The International Symposium on Genetic Biocontrol of Invasive Fish that Minnesota Sea Grant convened in Minneapolis, Minnesota addressed the potential of genetic biocontrol against established invasive finfish species and the risks associated with its use. Genetic biocontrol refers to release of genetically manipulated organisms designed to disrupt the survival or reproduction of a targeted invasive species. Genetic biocontrol strategies have the capability to be more effective and targeted than current control methods, all of which have major flaws.

The symposium involved nearly 60 fisheries managers, industry representatives, and government regulators. The objectives of the symposium were to:

  • Review the status of genetic biocontrol technologies for aquatic invasive species and develop a research agenda;
  • Consider methods for environmental risk assessment and develop a roadmap for risk assessment of genetic biocontrol of aquatic invasive species;
  • Discuss stakeholder involvement regarding this technology;
  • Examine the regulatory context for genetic biocontrol of invasive fishes and mussels; and
  • Consider the economic impacts of aquatic invasive species and of genetic biocontrol technologies.
