Climate Connections: Wisconsin’s lakes are warming up. That may spell trouble for species below the surface

With its big, glassy eyes and sharp teeth, the fish has wriggled its way to icon status among Wisconsin’s wildlife. Known as ogaa in the Ojibwe language, the fish has long been a cultural and dietary staple for tribes in the Great Lakes. And for the many anglers casting their lines across the state, the walleye has become a prized catch.
