The sauger's native range is southern Canada east to New England, south to Arkansas and Tennessee, and west to Montana and Wyoming. In Wyoming, it is found in the Wind-Bighorn drainage, Clear Creek in Sheridan County, and the Tongue River. Sauger were native to the North Platte drainage but have apparently disappeared from the stream. Preferred habitat includes larger streams and associated reservoirs. Young sauger feed on aquatic insects and crustaceans while large sauger primarily eat fish. Spawning takes place in the spring when water temperatures reach forty- three degrees Fahrenheit. Eggs are deposited randomly and are left unattended to hatch.
