Walleye
Description
Walleye have slender bodies and are fast swimmers. They have two separate dorsal fins, with spines on the first set, as well as on the anal fin. They are mottled in color, ranging from yellowish to greenish-brown with white bellies, and they have six to seven dark bands running vertically down their side. Walleye have large, marble-like eyes that help them feed in near darkness. These eyes also shine under a light at night. The jaws and roof of the mouth have sharp, prominent teeth.
Where They Live
Walleye prefer cool water, usually less than 85 F, even living under the cover of ice in the winter. They are usually found at depths of over 10 feet, not only because of their preference for cold water but also to accommodate the specific needs of their eyes. Walleye can see very well in near dark conditions but are sensitive to bright light.
What They Eat
Walleye are carnivorous so they feed on other fishes, including other walleye. Yellow perch is a common prey, as are the young of nearly any other fish. They have sharp, needle-like teeth and are opportunistic feeders, eating insects, worms, and crustaceans when available.
When young, the walleye will eat crustaceans and various insects and insect larvae exclusively until their teeth and bodies are up to attacking the more difficult fish.
When They Spawn
Walleye spawn in the early spring when the temperatures reach between 45 to 50 F. Females scatter their eggs at random throughout the water and several males fertilize the eggs. The spawning sites can be gravel or sand bottoms. The eggs are adhesive and, once dispelled from the female, stick to the surrounding vegetation and rocks. The eggs will hatch in 7 to 10 days. Walleye first spawn between the ages of two and six.
