Zebra and Quagga Mussel Mitigation

Zebra and Quagga Mussel Mitigation

May 30-31, 2024 | Online :: Central Time

“A top-notch presentation with lots of practical and useful advice for the novice and for the experienced person handling current and future zebra and quagga mussel issues!” Fishery Biologist, FERC

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 following:

  • biology of mussels
  • distribution patterns
  • early identification and prevention techniques
  • adverse impacts of invasive mussel infestations
  • control techniques
  • 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.
