New Zealand Mud Snails Invade Lake Erie!

Ann Arbor, MI — Exotic New Zealand mud snails continue to expand their range in North America.

The snail was found at several sites in three locations in Lake Erie (near Buffalo, NY, Erie, PA, and Put-in-Bay, OH). "Because the snail was found in such diverse locations, it is likely that it has been established in Lake Erie for some time," says Ed Levri, a biologist at Penn State - Altoona. "It has probably avoided detection due to its small size and the fact that it appears to be relegated to relatively deep water."

The New Zealand mud snail is an invasive species native to New Zealand. Populations of the species have been established in North America for at least 15 years. One large population exists in rivers of the western United States where they appear to be responsible for substantial ecological damage. A population can also be found in the Great Lakes, where, until now, have been found only in Lakes Ontario and Superior.

Since 1967, IAGLR has served as the focal point for compiling and disseminating multidisciplinary knowledge on North America's Laurentian Great Lakes and other large lakes of the world and their watersheds. In part, IAGLR communicates this knowledge through publication of the Journal of Great Lakes Research, available to members in print and electronic form. A searchable archive of the journal is available online and includes the abstracts of articles from the journal's inception in 1975 through the most recent issue. In addition, complete articles are available to members who have signed up for an electronic subscription.
