Tinca tinca Egg Incubation time 2 [25°C] or 3 [20°C] 2.0 days
Carassius carassius Egg Degree-days for incubation 80-100 [6 days at 18-19°C in natural conditions, or 3 days at 24-28°C] 90.0 °C * day
Tinca tinca Egg Degree-days for incubation 50-60 [2 days at 25°C, 3 at 20°C] 55.0 °C * day
Carassius carassius Egg Temperature for incubation 24-28, temperature for the shortest embryonic development [Eggs hatched normally at 15-28°C, but died at 5-10, and above 30°C] 26.0 °C
Tinca tinca Egg Temperature for incubation 19-24 21.5 °C
Carassius carassius Larvae Temperature during larval development 20-25, maximum size obtained and highest yolk utilization efficiency [At 5°C, no increase but the larvae were deformed and all died after 8 days] 22.5 °C
Carassius carassius Larvae Full yolk-sac resorption At 20 and 25°C, a maximum size of 7.6 mm, and at 30°C, 7.4 mm was achieved. The survival time (50% mortality) on yolk sac energy was 8 days both at 5 and 25-30°C, 9 days at at 20°C, and 14 days at 10-14°C. Even when Artemia nauplii were available on the fourth day, feeding (food in the gut) was noted at 15°C only, but its importance even here is not known since all died at the embryonic stage 27.5 °C * day
Carassius carassius Larvae Onset of exogeneous feeding When food are available from the start, larvae began mixed feeding at lengths of 6.5-7.2 mm, after 2-4 days of development at 20-30°C, when much of the yolk was present 6.85 °C * day
Carassius carassius Larvae Initial larval size 4.5-5.5 5.0 mm
Carassius carassius Larvae Larvae behaviour In nature, the free embryo are passive and often attach themselves to plants, where they stay hiding for the first 1-2 days of the endogenous feeding period Demersal
Carassius carassius Spawning conditions Spawning release Multiple (fractional) spawner Ambiguous
