How many eggs do walleye lay each season?

Walleye typically lay between 30,000 to 600,000 eggs each season, depending on the size and age of the female. Spawning usually occurs in the spring when environmental conditions are favorable, such as water temperature and flow. The eggs are often laid in shallow, gravelly areas where they can adhere to substrate and receive adequate oxygenation. After laying eggs, walleye do not provide parental care, and the eggs hatch within a few weeks.
