The sauger (Sander canadensis) is a freshwater perciform fish of the family Percidae that resembles its close relative, the walleye. The species is a member of the largest vertebrate order, the Perciformes. It is the most migratory percid species in North America. Saugers have two dorsal fins; the first is spiny and the posterior dorsal fin is soft-rayed. Their paired fins are in the thoracic position and their caudal fin is truncated, which means squared off at the corners, a characteristic of the family Percidae. Another physical characteristic of saugers is their ctenoid scales, which are common in advanced fishes. Saugers have a fusiform body structure, and as a result are well adapted predatory fishes and are capable of swimming into fast currents with minimal drag on their bodies.…
