Associated characteristics

Species Development state Trait Primary Data Secondary Data
Coregonus lavaretus Egg Temperature for incubation Water temperature was 4°C in November-December, and then it increased gradually up to 6°C in late March-April. These temepratures are in the range of optimal temperatures for C. lavaretus embryos. 4.0 °C
Coregonus lavaretus Egg Degree-days for incubation Hatching began at highest salinity (6.2 ppt) at 220 degree-days after fertilisation. Time of hatching at 50% of larvae decreased from 616 degree-days at 0.2 ppt to 470 degree-days at 4.8 ppt and 239 degree-days at 6.2 ppt […] Percentage of abnormal free embryos was ~ 20 at 0.2-2.5 ppt but increased rapidly at higher salinities 1.35 °C * day
Coregonus lavaretus Larvae Initial larval size Peipsi whitefish has TL at hatching of 10.8-12.4 mm. In the present study the maximum TL (> 11 mm) was observed at 1.9-3.5 ppt. At the salinity with the highest embryonic survival (0.5 ppt) average TL was 10.6 mm 11.6 mm
