Handy Cards Help Identify Zebra Mussels

September 1999

by Sea Grant Staff

You can help slow the spread of zebra mussels from the Great Lakes into inland lakes and rivers. Zebra mussels can be spread from lake to lake on the bottom of boats, and in bait and bilge water. If you know what zebra mussels look like, you will be more likely to take precautions to prevent their spread.

Minnesota Sea Grant, through the Great Lakes Network, offers wallet-sized cards with color pictures of zebra mussels. The text describes their appearance and what to do if you find any of these invasive mollusks.

Single copies of the Zebra Mussel WATCH identification card are free. One hundred cards or more cost 7 cents each. Look on the publications page and our free order form, under the exotics category, item X1, to order.
