Perca flavescens Egg Incubation time 27 days [8.5-12°C] 10.25 days
Perca flavescens Egg Degree-days for incubation 229-300 [About 27 days at 8.5-12°C] 264.5 °C * day
Perca flavescens Larvae Initial larval size 5.5-6.0 5.75 mm
Perca flavescens Larvae Larvae behaviour Immediatly active swimmer Demersal
Perca flavescens Larvae Temperature during larval development In general, water temperatures varied between 10 and 22°C and it is suspected that this range prevails in the shallow waters of the natural spawning grounds. In other studies, specimens were raised under hatchery conditions around 20°C 10.0 °C
