How is climate change impacting Wisconsin's fish population?

Ocean temperatures are on the rise. And a recent study by Penn State University concluded that temperatures in many American rivers and streams are also going up. Dr. Greg Sass is the fisheries research team leader with the Wisconsin DNR’s Office of Applied Science. This week on “Water Stories,” he joins host Greg Michaud to explain how temperature changes, drought conditions, and ice cover has impacted Wisconsin's fish population.
