Activities associated with the purchase, sale, and use of commercially available organisms or “organisms-in-trade” can potentially result in the introduction of aquatic invasive species (AIS) to waterways such as the Great Lakes. Preventing these introductions is a much more cost-effective way to protect waterways, as opposed to the cost and effort involved in controlling or managing them once they become established.
 
Building on a University of Notre Dame-led project to examine the environmental risks posed by certain “organisms in trade” (OIT), Illinois-Indiana Sea Grant has been awarded grant funding through the Great Lakes Restoration Initiative (GLRI) for a project titled “GLSGN OIT Initiative – Expanding Risk Assessment Outreach.”
By creating an opportunity to remove these potentially invasive species from circulation, risk assessment is one way to prevent non-native species from becoming invasive. Risk assessment information is also important to AIS education, because studies have shown that education and outreach encourage and shape the behavioral changes necessary for preventing species introduction. For example, horticulturists decided against purchasing a given species once they learned it had the potential to become an invasive species.
 
This new GLRI grant provides for the creation of new risk assessment and OIT outreach tools including webinars, a training video, non-technical summaries of state laws and regulations, and publications for people involved with fish, reptile, and amphibian commerce. Development of these tools will be guided by a survey that assesses the needs and preferences of OIT user groups. The goal of all these efforts is to reduce the introduction of potentially invasive species, thereby helping to protect and preserve waterways from invasive threats.
 
This initiative, a collaboration among the Great Lakes Sea Grant Network, North Carolina State University (NCSU), the National Sea Grant Law Center at the University of Mississippi School of Law (NSGLC), and IISG, will also help educate and inform the public about alternatives to high-risk aquarium, water garden, bait, live food, and classroom species.

When participating in a crayfish participatory science activity, be sure to snap plenty of photos of any crayfish you catch or observe. Not only is it a great way to capture the fun and excitement of the day, but it also helps document the species present. To ensure accurate identification by scientists, it’s important to provide clear photos from multiple angles. Dorsal (top), lateral (side), and ventral (underside) views of the crayfish should always be photographed.To learn more about the specific features to highlight in your photos visit the link in bio or InvasiveCrayfish.org/Management/#Community
Who says “Back to School” means back indoors? While the weather is still warm, take your students on an outdoor science adventure by exploring crayfish in your local waterways.The Invasive Crayfish Collaborative invites grades 2-12 educators to take part in a hands-on participatory science activity. By catching, identifying, and reporting crayfish species in your area, students contribute valuable data that helps scientists better understand where native and invasive crayfish live.Check out what other educators have found and get involved: inaturalist.org/projects/great-lakes-crayfish
