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.
