Lake Trout are a prized sport fish, but they are also considered a keystone species to the health of Lake Superior—now the only Great Lake where you can still find this critically important fish. Without Lake Trout, the ecological balance of Lake Superior would suffer, and that’s why Fisheries Biologist Shawn Sitar with the Michigan Department of Natural Resources has such a passion for the study and preservation of Lake Trout. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with Shawn Sitar about the most extensive and expensive egg hunt of his career, hunting for spring spawning Lake Trout 400’ deep off the north shore of Isle Royale.
