Minnesota State Fish
Walleye (common name) Sander vitreus (scientific name) Overview The walleye is a large freshwater perch (not a pike, as is commonly thought) with a long, olive-colored and gold-flecked body. There is a distinct black mark on its dorsal fin, and its tail has a white tip on the lower fork. It is a highly prized sport fish due to its size, fighting ability, and flavorful meat. Walleyes migrate to suitable spawning grounds, sometimes as far as 100 miles away. This fish was designated the official state fish of Minnesota in 1965. The walleye is also the state fish of South Dakota and the state warm water fish of Vermont. Close-up STATUS Official PHYSICAL DETAILS Length: Up to 42 in (107 cm); average of 36 in (90 cm) Weight: Up to 22 lbs (10 kg); average of 11 lbs (5 kg) LIFESPAN Up to 26 years HABITAT Large, cool lakes and rivers with low to moderate clarity and sand or gravel bottoms. Range: Throughout Canada and in the United States from the Dakotas to Arkansas, east to North Carolina, and up the Atlantic Coast to Maine. The walleye has been widely introduced all over the U.S. Water type: Freshwater Water temp: 65-75°F (18-24°C) Elevation: Down to 89 feet (27 m) Conservation Status: Secure DIET Young walleye eat insect larvae and plankton. As they mature they switch to insects and then fish like yellow perch, ciscoes, and freshwater drum. They also eat insects, crayfish, snails, leeches, worms, mudpuppies, crayfish, frogs, snails, and even small mammals like mice. REPRODUCTION Fertilization: External Spawning frequency: April to June Mating behavior: Several males will pursue females in the evening and circle them repeatedly with their fins erect. Egg laying: A female lays up to 500,000 eggs. The eggs adhere to rocky lake bottoms in relatively shallow water, where they are dusted by the male’s milt to become fertilized. The "fry" hatch after 20 days. Adults do not protect or care for the eggs or fry. USES Game fish, commercial fish OTHER NAMES Walleyed pike, jackfish, doré, dory, blue walleye, yellow walleye TRIVIA The name walleye refers to the large, milky pupils of the fish that reflect light back (like cat’s eyes) due to crystalline matter in the retina. These pupils allow the fish to see in dark, murky waters. People in Minnesota eat more walleye than residents of any other state.
