Jan Dean, Ph.D.

Jan Dean, Ph.D Fisheries Science Virginia Tech University 1982, has taught five-day electrofishing courses for the USFWS National Conservation Training Center in several states (MO, AR, LA, AL, FL, NM, AZ, MI, CO), some multiple times, and in New South Wales, Australia since 2008. He has also taught three-day electrofishing classes in CA and AZ for the Northwest Environmental Training Center. Jan has served as an instructor/consultant for an electrofishing workshop in CO and for two workshops for the Missouri Department of Conservation. He served on the graduate committee for two MS students at the University of Missouri for a project involving electrofishing for Smallmouth Bass, Blue Catfish and Flathead Catfish. Jan has served as an instructor for electrofishing workshops at AFS meetings in Savannah GA, Kansas City MO and Oklahoma City OK. Jan has authored or co-authored papers on output performance of boat and backpack electrofishers, on response of invasive species to electricity and on the historical development of electrofishing.  He has made presentations on electrofishing research at American Fisheries Society meetings and has consulted on projects involving evaluation of unique boat electrofishers and on electrical barriers to control movement of invasive species. Jan has worked for the University of Arkansas at Pine Bluff, for the Oklahoma Department of Wildlife Conservation, for Northwestern State University of Louisiana, and he retired from the Fish and Wildlife Service.

Please bring a scientific calculator and a pen or pencil, and notepad if you would like to take notes (you may also choose to take notes in your book). Lunch will be on your own, but drinks and snacks will be provided throughout the day. Lunch will be provided on the field trip days. 

In order to guarantee a space in a course, the tuition must be paid in full TWO WEEKS before the first day of the course by either check or credit card. State and government agencies paying with a purchase order are allowed payment under the two-week time frame if a copy of the purchase order is received by NWETC.
