AQUATIC INVASIVE SPECIES
Over 180 non-native species have been introduced into the Great Lakes region. Some of these species such as the zebra mussel, Eurasian watermilfoil and silver carp have flourished and negatively impacted both our environment and economy. Even more aquatic invasive species (AIS) such as these lurk on the horizon as threats to Lake Michigan and the inland waters of both Illinois and Indiana.
AIS can be introduced and spread through a variety of activities including those associated with recreational water users, water gardeners, aquarium hobbyists, and nursery tradespeople. For example, when an angler releases bait fish at the end of a day’s fishing or a water gardener disposes of excess plants in a local waterway, they could also be accidentally introducing AIS. IISG works with these groups to provide the tools they need to avoid AIS-risky behaviors.

Clean Boats-Clean Tournaments
Fishing tournaments have the potential to spread AIS through movement of both anglers and equipment between events. By implementing best management practices, tournament organizers can help stop the spread of AIS and protect the future of tournament fishing.
Be a Hero-Release Zero ™
Be a Hero – Release Zero is an Illinois program that gives gardeners and pet owners the information they need to help prevent the spread of AIS.

Be a Hero – Transport Zero is an Illinois program that gives recreational water users the information they need to help prevent the spread of AIS.
Organisms in Trade
Aquatic invasive species (AIS) can be introduced into new water bodies through a pathway known as organisms in trade (OIT). This pathway includes aquarium release, water garden escape, study organism release, live food and aquaculture release, and live bait.
Many aquatic invasive species have spread to the Great Lakes through recreational water use. Once established, these invaders hinder boating and swimming, disrupt food webs, and harm local economies. Fortunately, boater, anglers, and others can help prevent the spread of AIS.
The latest information on Asian carp includes how to identify, catch, clean and cook the fish and protect yourself while boating through Asian carp-infested waters.
Aquatic Plants in Trade
Through a science-based assessment of risk, best management practices and outreach, IISG is working to help reduce the introduction of invasive aquatic plants to our waters.

This educational web site introduces students (grades 4-10) to marine and freshwater invasive species and their impacts through colorful cartoon characters.
Safe Disposal of Classroom Specimens
Classroom specimens can end up part of the invasive species problem. With more information, schools and suppliers can be part of the solution.
