Walleye (Sander vitreus), also known as yellow pike or yellow pickerel, is a freshwater fish native to the lakes and rivers of North America, particularly abundant in the northern United States and Canada. It is a valued sport fish and holds significant culinary importance in the Upper Midwest of the United States and throughout Canada, regularly featured in regional dishes such as fried walleye.
The flesh is white, flaky, and mildly flavored, known for its delicacy and low fat content, with a taste profile described as clean and slightly sweet.
Walleye may contain mercury, with levels varying depending on the body of water; consumption advisories exist, particularly for pregnant women and children. While walleye populations remain stable in many areas due to regulated fishing and stocking practices, some localities have experienced declines from overfishing and habitat loss, resulting in specific conservation measures to protect stocks.
