 WalleyeStitzostedion vitreum |
| 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 |
