Sauger Sauger is a close relative the walleye. However, they are usually smaller and tolerate higher turbidity waters. They are distinguished from walleyes by a distinctly spotted dorsal fin and the lack of a white spot on the tail. Sauger are sometimes called the "sand pike." Sauger are usually less than 3 pounds and 18 inches in length.
Spawning occurs from April through May in a variety of places with the tailwater areas providing good spawning habitat, as observed in the sport catch during this time of the year. Sauger feed almost exclusively on fish.
