Preventing the Spread of Invasive Species

URBANA-Would you recognize a zebra mussel if you saw one? Can you tell a sculpin from a round goby? If you can, you could be instrumental in helping prevent the spread of invasive species to lakes and rivers in Illinois. The zebra mussel is an invasive species that can clog boat engine cooling systems, foul boat hulls and change the ecology of inland waters. The sculpin is a small fish, native to lakes and streams in much of North America, while the round goby is an invasive species which can threaten the existence of the sculpin.
How to identify the zebra mussel and the round goby are just two of the things participants will learn at workshops being offered by University of Illinois Extension Specialists in cooperation with Illinois-Indiana Sea Grant. Patrice Charlebois, Biological Resources Specialist with Illinois-Indiana Sea Grant said, "Increasingly, exotic species are becoming a problem in lakes and rivers. These workshops will help people identify some key exotic species, and learn about their biology and potential impact. They'll also hear about ways that people can help prevent the spread of exotic species."
Anglers, boaters and other water recreationists are often among the first to spot a new invader in aquatic systems. If they recognize the invader and report it to the authorities, the spread of the invader to another body of water can be prevented. But if they are not familiar with the subtle differences between, for example, the sculpin and the round goby they may inadvertently aid the invasive species' spread by transporting it to another inland lake or river.
Charlebois continued, "Zebra mussels have already invaded our inland lakes and rivers, in many cases by hitching a ride on recreational boats, unbeknownst to the boat owner. This accidental spread of invasive species can be prevented almost entirely by following a few guidelines that will be presented at these workshops. I would encourage anyone who depends on the area lakes and rivers for income or recreation to attend."
