The Sauger (Saner canadensis) is a freshwater Perciform fish of the family Percidae which resembles its close relative the walleye. Saugers, however, are usually smaller and will tolerate waters of higher turbidity than will the walleye. In many parts of their range, saugers are sympatric with walleyes. They may be distinguished from walleyes by the distinctly spotted dorsal fin, by the lack of a white splotch on the caudal fin, by the rough skin over their gill, and by their generally more brassy color, or darker (almost black) color in some regions. The average sauger in an angler's creel is 300 to 400 g (0.75 to 1 lbs) in weight but the world record was 8.1 kg (17 lbs, 12 ounces.) Saugers are more typical of rivers whereas walleyes are more common in lakes and reservoirs. The sauger is highly prized as a food fish.
