Incubation time for trout is temperature dependent. The cooler the water, the longer it takes for the eggs to hatch, and as water temperature increases, the incubation time decreases.
| Water Temperature °F (°C) | Days to Hatch |
|---|---|
| 45 (7.2) | 48 |
| 50 (10.0) | 31 |
| 55 (12.8) | 24 |
| 60 (15.6) | 19 |
