| Species | Development state | Trait | Primary Data | Secondary Data |
| Salvelinus alpinus | Egg | Oocyte diameter | Charr eggs are usually 4-5 mm in diameter | 4.5 mm |
| Salvelinus alpinus | Egg | Temperature for incubation | Mean (SD) hatching success was 47 (30)%for eggs incubated at 6°C, and increased to 65 (30)% for egg batches incubated at 3°C | 47.0 °C |
| Salvelinus alpinus | Egg | Degree-days for incubation | The time from egg fertilization to hatch is 350-500°C-days, depending upon the source of eggs and the incubation conditions | 425.0 °C * day |
| Salvelinus alpinus | Female | Relative fecundity | In general, a relative fecundity of 3000-4000 eggs per fish kg fish may be expected | 3500.0 thousand eggs/kg |
| Salvelinus alpinus | Spawning conditions | Spawning season | In the wild, Arctic charr usually spawn in the autumn at water temperatures of about 4°C | ['October', 'November', 'December'] |
| Salvelinus alpinus | Spawning conditions | Spawning period duration | Spawning duration of 4-5 weeks | 4.5 weeks |
| Salvelinus alpinus | Spawning conditions | Spawning temperature | Spawning may be inhibited at temperatures over 10°C, the timing of ovulation may be delayed at 8°C compared to lower temperatures, and the process of egg over-ripening is greatly accelerated at temperatures above 5°C | 10.0 °C |
