Hobbies: I like all forms of recreational fishing, but love fly-fishing and fly-tying. To relieve tension, I listen to music, mostly jazz (John Coltrane, Miles Davis, Sonny Rollins) and popular (Jackson Browne, Van Morrison, Neil Young). Hiking, backpacking, and canoeing are essential for my mental health.

I teach one-third of the lectures and 1-2 of the laboratories associated with one of our introductory courses, Introduction to Fishery, Forestry, and Wildlife Resources (Natural Resources 250). This course is designed to integrate aspects of the management of living natural resources, as part of the introductory core curriculum for all students in the College of Natural Resources. I also teach one-half of the lectures and 1 lab section for Wildlife and Fisheries Population Dynamics (Water/Wildlife 353/553). I also teach two senior-level courses in fishery science, one entitled Fisheries Research (Water 483), which provides training in fisheries techniques in the context of the research process, and another entitled Fishery Management (Water 484), which provides training in the process of fishery management. Each of these courses includes two 1-hour lectures and one 2-hour laboratory each week. The lectures for each course are intended to communicate key concepts, which draw heavily from my experience as a fishery researcher and fishery manager. The lectures are interactive, to draw students into the thought-processes of fishery research and management. The labs are designed to provide experience in all aspects of fishery research and management.

My research is focused on applied, rather than esoteric, areas of fishery science, within the realm of fish population dynamics, predator-prey interactions, and fishery management. For example, I have ongoing research on the population dynamics and fishery management of lake trout in Lake Superior. To the right, my colleague Chuck Bronte is holding a wild lake trout from Stannard Rock in Central Lake Superior. I also have ongoing research on the population dynamics of walleye in northern Wisconsin. Previously, I worked on the ecology of benthic fishes in warmwater streams and predator-prey dynamics of coolwater fishes in Great Plains reservoirs. My recent research includes questions that serve the fishery research needs of the Wisconsin Department of Natural Resources and other fishery agencies in the Great Lakes basin (see below).

I advise undergraduates who declare an interest in emphasizing fisheries in the College of Natural Resources. We currently average 75 undergraduates who are emphasizing fisheries in the college. I also serve as the faculty advisor for the UWSP Student Sub-Chapter of the Wisconsin Chapter of the American Fisheries Society. We are involved in several student projects each semester, each of which provides practical experience for upcoming fisheries professionals. I encourage all of my undergraduate advisees and graduate students to become involved in the chapter. I currently serve as Coeditor for the North American Journal of Fisheries Management, and have been a member of the American Fisheries Society since 1986. I presently serve as a U.S. Commissioner to the Great Lakes Fishery Commission and also serve as a member of the GLFCs Board of Technical Experts.

Effects of Macrophyte Removal on the Fishery for Predator and Prey Fishes in Fish Lake, Dane County, Wisconsin. The project was funded by the Wisconsin Department of Natural Resources to investigate the effects of the removal of Eurasian watermilfoil on bluegill and largemouth bass, and the associated fishery for both species. Eurasian watermilfoil is an exotic plant that has invaded many Wisconsin lakes and caused numerous problems with the fisheries of those lakes. The project was funded for two years, from September 1, 1996, to August 31, 1998. Jean M. L. Unmuth was the graduate student working on this project, and graduated in December 1998. Jean is now working for the Wisconsin Department of Natural Resources.

Modeling the Effects of Angling and Spearing Exploitation on Walleye Populations in Northern Wisconsin Lakes. The project was funded by the Wisconsin Department of Natural Resources to model the rate of exploitation that can be sustained by walleyes living in northern Wisconsin lakes. The project integrated long-term data on walleye in Escanaba Lake into a population model for use in forecasting effects of changes in spearing and angling harvest strategies. The project was funded for two years, from January 1, 1997, to December 31, 1998. Justine R. (Newby) Hasz was the first graduate student working on this project, and graduated in May 1999. Justine is now working for the Wisconsin Department of Natural Resources. After a 4-year hiatus, the project was funded for another 2.5 years, from January 1, 2003, to June 30, 2005. Amy M. Schueller is the second graduate student working on this project, and graduated in August 2005.  Amy is now working on her doctoral degree at Michigan State University.

Lake Trout Movements in Northwestern Lake Michigan. The project was funded by the University of Wisconsin-Stevens Point, Wisconsin Cooperative Fishery Research Unit, and U. S.

The project is funded for three years, from March 1, 1998, to February 28, 2001. Jessica M. (Doemel) Richards was the first of two graduate students working on this project and graduated in December 2000. Jessica is now working for the U. S. Fish and Wildlife Service. Brian C. Linton was the second graduate student working on this project, which linked to my new Sea Grant project, Development of a Lake Trout Population Model for Lake Superior (see below).

Mike's project was to analyze spatial and temporal patterns of the historic large-mesh gill-net fishery as lake trout stocks collapsed in Lake Superior. Mike is now an assistant professor at the University of Maryland's Chesapeake Biological Laboratory. Jennifer A. Devine was the second graduate student working on the project and graduated in August 2002. Jennifer's project was to model food web dynamics in Chequamegon Bay, Lake Superior. Jennifer is now a fishery biologist in the Middle Depth Fisheries and Acoustics unit of the National Institute of Water and Atmospheric Research in New Zealand.

Casey graduated in May 2004 and is now studying for his doctoral degree at South Dakota State University.

Development of a Lake-Wide Lake Trout Population Model for Lake Superior. The project was funded by the U. S. Fish and Wildlife Service to model lake trout movements in Lake Superior. The project relied on tag-recapture to quantify rates of movement by lake trout among management areas in Lake Superior, for use in population models being concurrently developed as parts of a larger, lake-wide project. The project was funded from September 1, 1999 to December 31, 2001. Kevin L. Kapuscinski was the graduate student working on this project and graduated in August 2002. Kevin is now studying for his doctoral degree at Syracuse University.

Development of a Lake Trout Population Model for Lake Superior. The project was funded by the University of Wisconsin Sea Grant College Program to develop a model of lake trout population dynamics in Lake Superior. The project is based on long-term lake trout stock assessment data collected by the states of Michigan, Minnesota and Wisconsin along the south shore of Lake Superior. The project was funded from March 1, 2001 to February 28, 2004. Brian C. Linton was the first graduate student working on this project, to carry forward with research begun under my earlier Sea Grant project, Causes and Impediments of Lake Trout Recovery in Lake Superior (see above). Brian graduated in August 2002 and is now studying for his doctoral degree at Michigan State University. Lisa M.

The project was funded by Wisconsin Department of Natural Resources to determine the extent to which walleye and muskellunge move among lakes and years within lake chains. The project will rely on numbered tags and radio transmitters to quantify fish movement after spawning in spring, up to the point of capture (for numbered tags) and throughout the year (for radio-transmitter tags). The project was funded from September 1, 2003 to August 30, 2005. Jordan G. Weeks was the graduate student working on the project and graduated in December 2006.  Jordan is now working for the Wisconsin Department of Natural Resources.
