Species Development state Trait Primary Data Secondary Data
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 Ambiguous
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 period duration Duration vary according to different sources from 1 day to 60, mostly 3-15 days 9.0 weeks
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
