Michael Kinnison, a professor of evolutionary applications at University of Maine, and other scientists are working with the state to make sure the fish keep surviving. Kinnison is working on a project to collect “environmental DNA” from the water bodies where the fish live. The project involves collecting water samples from the lakes and ponds where the fish are known to live, and studying DNA that they and other organisms shed, Kinnison said. A local chapter of Trout Unlimited, an environmental non-profit, is working on the project using grant money provided by the organization’s Embrace-A-Stream fund. The fish like cold water, and they’re at the very southern end of their range in Maine.
