Feed and growth

Feed protein: 42% target
Daily feed (warm): 1.80% of body weight
Daily feed (cool): 0.60% of body weight
Max density: 25 g per litre

A 2000 g adult eats about 36.0 g of feed per day at optimum. 10 fish at adult size: ~360 g daily.

Origin and habitat

A hybrid between walleye (Sander vitreus) females and sauger (Sander canadensis) males, produced both naturally where both parent species coexist and deliberately in state hatcheries for recreational fisheries stocking. The hybrid exhibits heterosis (hybrid vigor): faster growth than sauger, better survival and adaptability in pond and reservoir conditions than pure walleye, and greater tolerance of warm, turbid water. Saugeye are widely stocked by state fisheries agencies across the Ohio River valley, Midwest, and central US for recreational fishing, where they provide walleye-like angling in waters too warm or turbid for walleye to thrive naturally. Adults reach 50–65 cm and 2–4 kg. The flesh is white, firm, delicately flavored, and identical to walleye at the table. Saugeye are partially fertile and can backcross with either parent species, raising concerns about genetic contamination of wild walleye and sauger populations in systems where all three forms overlap.

Care notes

A cool-water predatory hybrid with slightly better culture potential than pure walleye or sauger, though still challenging for aquaponics. The hybrid's practical advantages are faster growth than sauger, better stress tolerance than walleye in warm or turbid water conditions, and slightly easier adaptation to feed training on pellets. Temperature range: 5–28°C, optimal at 20–24°C (roughly 2°C warmer tolerance than pure walleye). Growth: 300–700 g in 18-24 months on high-protein pellet (42-48% protein). FCR is estimated at 1.8-2.5 for individuals successfully trained on pellets. Feed training must start with very small fingerlings (under 5 cm); larger fish resist conversion from live food. Stocking density: 10-18 g/L. Dissolved oxygen above 5 mg/L; ammonia below 0.5 mg/L. Fingerlings are available from state hatcheries that produce saugeye for recreational stocking programs; some sell surplus to private buyers. Availability is inconsistent, typically limited to spring, and quantities may be small. For aquaponics operators in the Ohio River valley and central US who want a native percid species, saugeye offer a better culture profile than pure walleye or sauger, combining the best attributes of both parents.
