Zebra and Quagga Mussel Mitigation
July 16-17, 2020 | Online :: Central Time

Download PDFPrint Event Details


Proliferation of invasive zebra and quagga mussels pose a host of challenges such as damaging or clogging industrial infrastructure, adversely impacting native fish and mussel populations, decreasing property value, and discouraging recreation. Whether you are a utility or a park and recreation department, invasive mussels are an expensive nuisance when populations aren’t controlled.

The Zebra and Quagga Mussel Mitigation training course will educate participants on the biology of mussels, distribution patterns, early identification and prevention techniques, the adverse impacts of invasive mussel infestations, control techniques, and touch on public communication strategies. This course will walk you through the steps of zebra and quagga mussel mitigation from monitoring and planning through control techniques and implementation.

Learning Objectives

After attending the course, participants will successfully be able to:

  • Describe zebra and quagga mussel biology including reproduction, population dynamics, growth patterns, and feeding
  • Define distribution patterns including vectors for population expansion
  • Recognize environmental changes due to mussel invasion
  • Explain the adverse impacts that mussels will have on the environment, recreation, drinking water plants, reservoirs, pipelines, and power plants
  • Identify general control strategies
  • Construct a zebra mussel monitoring program beginning with detection upon first arrival
  • Anticipate infestation challenges and identify a control method
  • Review other biofouling challenges
  • Apply public outreach and communication strategies

Wrap up: Questions, Comments, and Remarks


Renata Claudi, Environmental Scientist, RNT Consulting

Ms. Claudi is an environmental scientist with over 30 years of diverse business and technical experience. After more than 15 years in the electric power industry, where she established the mussel mitigation program for Ontario’s largest electricity utility, Ms. Claudi formed RNT Consulting Inc. to respond to the broader industry need for expert mussel support. As aquatic nuisance species became geographically more widespread, Ms. Claudi has provided mussel expertise internationally on the various aspects of alien species invasions, including their economic impact, protection of assets, selection of appropriate control options, and installation of these control options.

Tom Prescott, Chief Engineer, RNT Consulting

Mr. Prescott has over 30 years of engineering and project management experience on design, installation, and testing of mechanical and process systems in various areas including military, petrochemical, and electric power production industries. Mr. Prescott has particular expertise in vulnerability assessments and pilot testing of control facilities for mussel biofouling control. He has experience with many clients throughout Canada, U.S.A., and overseas and is currently a partner and senior project engineer at RNT Consulting Inc.

Dan Butts, Vice President Biofouling of Services, ASI

Daniel’s experience in the ecological industry spans over 28 years. Daniel has been with ASI since 1992 and his experience includes development of zebra mussel control protocols and installations, development of turnkey mussel mitigation programs, research and development of potash as a method of control within fire protection systems, development of open water mussel eradication protocols, client relations, and contract administration.  Most recently he has designed and successfully completed an open water eradication of zebra mussels, using potash as the control agent, at Hyde’s Quarry in Maryland.

He is currently Vice President Biofouling of Services, Daniel specializes in engineering, ecological and marine services for industries and municipalities worldwide.
