DNR Asks Anglers to Scrape DNA from Lake Superior Trout

Scientists with the Minnesota Department of Natural Resources are enlisting the help of anglers in an effort to restore a trouble trout population in Lake Superior. 

The scientists hope that by asking anglers to scrape DNA off their catch, they can figure out if their efforts to save the wild steelhead trout have been helping or harming the depleted fish population.  They believe a non-reproducing relative, known as Kamloops, could be hurting wild reproduction. 

According to the St. Paul Pioneer Press, officials with the DNR will formally announce the new study Saturday at the Great Waters Fly Fishing Expo in White Bear Lake. 

The nonprofit Minnesota Steelheader will help distribute free kits for anglers to collect scales of wild fish and send them to the department for DNA analysis.
