| Common name: |
Walleye |
| Scientific name: |
Stitzostedion vitreum |
| Production potential: |
Moderate for fingerlings, difficult for food
size due to their cannibalistic nature |
| Marketing potential: |
Potential:High
Size: 2-4" for fingerlings, 1-3 pounds for food size
Market: Sport and Food |
| Temperature Requirements: |
Growing: 69-72 F
Spawning: 40-50 F
Lethal: NA |
| Feed requirements: |
Protein: 45%
Fat: 10-15% |
| Spawning requirements: |
Broodfish produce 30,000 eggs/lb body weight.
Spawns may be obtained by stripping eggs from ripe females and mixing with milt from males
in a dry container, mixed thoroughly and then water is added to activate the sperm and
permit fertilization. Eggs hatch in around 10 days at 44-55 F occurs |
Most common
production systems: |
Fingerlings are produced in fertilized ponds
stocked a 100,000-150,000 fry per acre. Food fish may be produced in ponds or cages if
cannibalism is prevented by grading to maintain a uniform size. Currently, there are no
good production rates for production of food size walleye |
