Many Michigan residents are aware of the damage caused to the Great Lakes by the more than 150 non-native species that have made their way into the lakes' watershed over the years.
Millions of dollars have been spent trying to control invasive aquatic life such as zebra mussels and round goby, both of which were discovered in the Great Lakes in the 1980s, most likely brought in by ocean-going freighters.
In addition to clogging intake pipes that affect industry, drinking-water facilities and boaters, zebra mussels filter out much of the phytoplank-ton and small zooplankton in the lakes, effectively starving native populations. Round goby compete with native species such as perch for food, as well as eating the eggs of other fish and chasing larger fish away from nesting sites. (More)
