Walleye is a freshwater fish species that is native to North America. They are a popular sportfish among anglers due to their large size, fighting ability, and delicious taste. Walleye have a distinctive pearlescent eye that appears to “glow” in low light conditions, which is where their name comes from.
They are carnivorous and feed on small fish, insects, and crustaceans. Walleye prefer colder water temperatures and are commonly found in lakes, rivers, and other bodies of water throughout the United States and Canada. They spawn in the spring and lay their eggs on rocks or other structures in shallow water.
Walleye have a relatively long lifespan, with some individuals living for over 20 years in the wild. They are a key species in many freshwater ecosystems, helping to control the populations of smaller fish and invertebrates.
Walleye are highly valued for their mild, flaky flavor and nutritional value, as they are a good source of protein, omega-3 fatty acids, and other important nutrients.
