Associated characteristics


Species Development state Trait Primary Data Secondary Data
Coregonus albula Egg Incubation time Eggs from Lake Pyhäselkä, incubated in the laboratory at 2.3°C, reached 50% hatching after 182 days incubation, but the same group in the lake at a temperature of 2.1°C, reached 70% hatching after 174 days, eggs from Lake Orivesi, incubated in the laboratory, (at 2.4°C), reached 50% hatching after 169 days, but eggs in the lake (2°C) reached 74% hatching after 164 days. Overall incubation days to 50% hathcing ranged from 119-217 168.0 days
Coregonus albula Egg Degree-days for incubation The number of DD from fertilization to 50% hatching ranged from 203-547 depending on egg group and incubation temperature 375.0 °C * day
Coregonus albula Egg Temperature for incubation Placed into incubation jars supplied with water of different constant temperatures from 0.7-4.1°C. When hatcing in the laboratory reached 10%, the incubation temperature in all jars was raised to 6°C 2.4 °C
Coregonus albula Egg Egg size after water-hardening Different means of diameter of water-hardened eggs range between 1.71 to 1.81 mm 1.71 mm
Coregonus albula Larvae Initial larval size Total length means vary between 7.07 to 7.94 7.07 mm
