Species | Development state | Trait | Primary Data | Secondary Data |
Coregonus clupeaformis | Egg | Incubation time | Hatching occurred between 84 and 101 days (mean of 94) at an average temperature of 3.4°C (± 0.3°C) | 84.0 days |
Coregonus clupeaformis | Egg | Temperature for incubation | Incubated at an average temperature of 3.4°C (± 0.3°C) | 3.4 °C |
Coregonus clupeaformis | Egg | Degree-days for incubation | 320 [Hatching occurred between 84 and 101 days (mean of 94) at an average temperature of 3.4°C (± 0.3°C)] | 320.0 °C * day |
Coregonus clupeaformis | Larvae | Initial larval size | 10.8-11.3 [Deduced from graph, at haching] | 11.05 mm |
Coregonus clupeaformis | Larvae | Temperature during larval development | Reared at 6.9 ± 0.6°C | 6.9 °C |
Coregonus clupeaformis | Larvae | Full yolk-sac resorption | 150-170 [Yolk-sac absorption occurred between 23 and 25 days post-hatch (at 6.9°C). Yet, water temperatures in their this experiment were maintained at relatively low temperatures to simulate temperatures normally encountered in the Laurentian Great Lakes, while in early study was conducted at 12°C. At this higher temperature, larval lake whitefish exhausted energy reserves between 12 and 15 days post-hatch] | 160.0 °C * day |
Coregonus clupeaformis | Larvae | Onset of exogeneous feeding | Larvae were not fed until just prior to yolk sac absorption (21 after hatching) [Yet under natural conditions; larval lake whitefish are capable of feeding within 48 h after hatching | 21.0 °C * day |
