Dan Isermann

I serve as Unit Leader of the Wisconsin Cooperative Fishery Research Unit. I earned my degrees from Southern Illinois University (BS), Tennessee Tech University (MS), and South Dakota State University (PhD). Before my employment with USGS, I was an assistant professor of fisheries at the University of Wisconsin-Stevens Point and worked as a fisheries biologist and research scientist with the Ohio and Minnesota Department of Natural Resources.. My research focuses on the population dynamics and management of exploited fish populations. My research endeavors are direct collaborations with state and federal resource agencies that are designed to address agency questions related to management of recreational and commercial fisheries. My current research projects are focused on: 1) recruitment of walleye and yellow perch in northern Wisconsin lakes; 2) movement of walleye, lake whitefish, and muskellunge in and around Green Bay; 3) spawning habitat and harvest management of lake sturgeon in the Lake Winnebago system; 4) effects of climate change on walleye stocking success and bluegill population dynamics and demographics in the Midwest region; 5) lake whitefish recruitment in Lake Michigan and 6) harvest management of muskellunge in northern Wisconsin lakes.. I teach a graduate level course covering fish population dynamics, fisheries management, and analytical methods frequently used in the assessment of fish populations.
