Associated characteristics


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
