Sander lucioperca Spawning conditions Spawning substrate Preferably roots, but can be sand, gravel or stones, from which ther males removes the silt to built its nest Ambiguous
Sander lucioperca Spawning conditions Spawning site preparation He guards the nest and attracts one female, after a 'mating dance' No category
Sander lucioperca Spawning conditions Spawning temperature When water temperature reaches 10-14°C depending on latitude 12.0 °C
Sander lucioperca Spawning conditions Spawning period duration Over a period of 2-3 weeks 2.5 weeks
Sander lucioperca Spawning conditions Spawning depth Spawns in depth from 1 to 5-6 m in rivers and up to 17 m in lakes 5.5 m
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
