Sander lucioperca Egg Degree-days for incubation Hatching usually occurs at 100-110 DD (at 14-15°C) but can occur earlier (65-90 DD) with a low viability if the eggs are small (diamer: 0.8-1 mm) 105.0 °C * day
Sander lucioperca Larvae Initial larval size 4.5-5.5 5.0 mm
Sander lucioperca Larvae Larvae behaviour Show alternate phases of upward swimming to the water surface and passive falling to the tank bottom Demersal
Sander lucioperca Larvae Reaction to light The hatched larvae are highly phototropic Photopositive
Sander lucioperca Larvae Temperature during larval development Temperatures lower than 10°C are lethal to the larvae 10.0 °C
Sander lucioperca Larvae Temperature during larval development Reared at 14-15°C 14.5 °C
Sander lucioperca Larvae Full yolk-sac resorption 100-110 at 14-15°C 105.0 °C * day
Sander lucioperca Female Relative fecundity 200 200.0 thousand eggs/kg
Sander lucioperca Male Male sexual dimorphism According to Hungarian aquaculturists sexually mature pike-perch can be sexed on the basis of external features; males have a darker abdomen than the females, and females show a white rounded belly, a broader head, and a higher back than males. In our experiments in early spring, these criteria proved to be unreliable Present
