White fish are running in the Great Lakes now. Fishermen brave the wind, snow, ice and wind after dark on the boardwalk and piers. They use a lure called the Swedish pimple and some are lucky enough to catch some whitefish.
Read more about the fish, both native, as are the whitefish, and planted as are Pacific salmon, in my book, The Dynamic Great Lakes.
The book is widely available at Amazon.com, bn.com and in many bookstores.
