A female Walleye may lay approximately 50,000 eggs in the span of one day during spawning.

Walleye are native to northern America. They prefer cooler temperature lakes, backwaters, and runs of medium to large rivers. A Walleye’s eyes reflect light, much like a cat’s, which allows it to see well in dimly lit and turbid water conditions. This gives the Walleye an advantage over their prey and allows them to populate the deeper parts of waters. Walleye feed mainly at night on perch and other small fishes, as well as aquatic insects. The oldest recorded age of a Walleye is 29 years. However, Walleye older than seven years of age are rarely encountered in the wild.

Walleye grow to about 30 inches in length, and can weigh up to 15 pounds. Like most fish, their size depends largely on the size and the location of the body of water they live in. Southern populations of Walleye grow faster and larger than Walleye in northern waters. Females in general grow larger than males. Walleye are olive and gold in color with a white belly. Walleye have an extremely sensitive lateral line system that allows them to detect minute vibrations in the water. This, combined with their excellent vision and sharp teeth, make them a formidable predator.
