Species | Development state | Trait | Primary Data | Secondary Data |
Coregonus albula | Egg | Egg size after water-hardening | Average diameter at pH 7.00 was 1.75 (based on Figure 1) | 7.0 mm |
Coregonus albula | Egg | Temperature for incubation | Eggs were incubated at 4°C until day 50, then temperature was gradually increased to 10°C (5°C until day 59, 6°C until day 79, 7°C until day 80, 8°C until day 99, 9°C until day 107) | 4.0 °C |
Coregonus albula | Larvae | Onset of exogeneous feeding | Vendace incubated at pH 7.00 and 7.40 started to ingest paramecia several days after hatching and began feeding on Artemia a week later. The fish at pH 5.50 started to feed on paramecia with 7 days delay compared to the controls | 7.0 °C * day |
