A physical barrier to stop Asian carp from making their way into Lake Michigan won’t be happening any time soon, but there are other ways to reduce the risks of these fish becoming established in the Great Lakes. From the latest issue of IISG’s The HELM: 
 
The men behind a new fish processing plant in Illinois aren’t veterans of the fishing industry. They are a lawyer, alloy company owner, and restaurant builder who saw Asian carp jumping in the Mississippi River and thought, “There must be something we can do with these things.” 
 
 
That thought became a reality this April when American Heartland Fish Products opened its doors in Grafton, IL, a small town near the confluence of the Mississippi and Illinois rivers. The plant uses a unique production process to turn Asian carp into fish and bone meal and Omega 3 oils. The high-protein meals are primarily sold to animal feed producers. Their biggest seller, Omega 3 oil, is used for everything from cosmetics to dietary supplements.
 
 
“There is a demand for these products that never quits,” said Ben Allen, who co-owns American Heartland Fish Products with Gray Magee and Bryan Lebeau. “I have been involved in a lot of businesses, but never one where there is such a demand for the product.” Read more.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
Managers and researchers can be faced with a need to classify the risk of new crayfish invaders. Rapid assessment tools, such as the Science-based Tools for Assessing Invasion Risk (STAIR), can assist in this process by providing a streamlined framework for analysis and decision-making.Join us for an ICC webinar with John Bieber from Loyola University Chicago to learn how rapid assessment tools are used to classify invasive species risk and how STAIR can support invasive crayfish management.Learn more at the link in bio.
