DISTRIBUTION:
New York state across the Great Lakes and into the Mississippi Valley to Minnesota and Canada. They are now found as far as south Alabama. HABITS: Found over sandy bottoms in clear water, more often in lakes than streams. SPAWNING: They spawn over gravel or rocky bottoms when temperatures are 38 - 44 oF April - May. Females typically lay 400,000 eggs. GROWTH: Under culture conditions walleye reach maturity at age 2 and. They can weigh up to 25 lbs. USES: Popular gamefish CULTURE: Using wild caught adults, it is easy to strip eggs and artificially spawn them. Unlike some freshwater species, mass rearing of fry is uneconomical under intensive culture conditions. The standard procedure for walleye is to raise fry to about a length of 4 inches in ponds, fertilize to produce heavy plankton blooms. They can be placed in floating pens, tanks and troughs for growout. Pelleted feed is prescribed. REFERENCES: .
