| Species | Development state | Trait | Primary Data | Secondary Data |
| Rutilus rutilus | Egg | Temperature for incubation | Optimum temperatures for embryonic development of roach eggs is between 12 and 24°C, while <8 and > 26°C all eggs will die | 12.0 °C |
| Rutilus rutilus | Spawning conditions | Spawning period duration | Duration vary according to different sources from 1 day to 60, mostly 3-15 days | 9.0 weeks |
| Rutilus rutilus | Spawning conditions | Spawning temperature | The onset of spawning is synchronized by photoperiod, and water temperature is important in regulating the intensity and duration of spawning. Spawning usually takes place in water temperature 8 and 17°C. Also found to spawner at a lower temperature (7.4°C) which coule be an adaptation to the colder climatein Norway. The onset temperature vary from differente sources from 7.8 to 18, mostly 10-14°C | 12.0 °C |
| Rutilus rutilus | Spawning conditions | Spawning substrate | It spawns generally on vegetation, but it can spawn also on the remnants of vegetation, other debris or even in stones | Lithophils |
