Species | Development state | Trait | Primary Data | Secondary Data |
Salvelinus alpinus | Egg | Oocyte diameter | Egg diameter in females held in different environmental conditions range from 4 to 5 mm | 5.0 mm |
Salvelinus alpinus | Egg | Temperature for incubation | Eggs were incubated in darkness and at 4.5°C until 100% hatching. The water temperature was then gradually raised to 8°C (0.5°C per day) until first feeding | 4.5 °C |
Salvelinus alpinus | Egg | Degree-days for incubation | Degree-days for incubation very from 400 to 450 (based on Figure 4) | 400.0 °C * day |
Salvelinus alpinus | Larvae | Temperature during larval development | Eggs were incubated in darkness and at 4.5°C until 100% hatching. The water temperature was then gradually raised to 8°C (0.5°C per day) until first feeding | 4.5 °C |
Salvelinus alpinus | Larvae | Onset of exogeneous feeding | First feeding was reached after 627 ± 13 degree-days in all families (less than 400-450 °D for incubation) | 627.0 °C * day |
Salvelinus alpinus | Female | Relative fecundity | The relative fecundity was similar among groups 2685 +/- 706 eggs | 2685.0 thousand eggs/kg |
