Zebra mussels, invasive species

Zebra mussels are an invasive species to Minnesota and can wreak havoc on our lakes. I  visited a Minnesota Sea Grant booth at the home show at the DECC today

What problems can they cause? Zebra mussels can:

 clog irrigation intakes and other pipes,

 attach to boat motors and boat hulls, reducing performance and efficiency,

 attach to rocks, swim rafts and ladders where swimmers can cut their feet on the mussel shells,  attach to and smother native mussels, and

 eat tiny food particles that they filter out of the water, which can reduce available food for larval fish and other animals, and cause more aquatic vegetation to grow as a result of increased water clarity.

    This doesn’t sound good. I wonder where the Zebra mussels came from?

      Hi Lowell, please click on the hyperlinked (or colored and underlined words) in my text. They will take you to the MN Sea Grant website which give more information about the Zebra mussels.
      Zebra mussels are native to Eastern Europe and Western Russia and were brought over to the Great Lakes in the ballast water of ships. Populations of zebra mussels were first discovered in the Great Lakes in 1988.
