Species | Development state | Trait | Primary Data | Secondary Data |
Perca fluviatilis | Spawning conditions | Spawning temperature | Range 8-16 | 12.0 °C |
Perca fluviatilis | Spawning conditions | Spawning period duration | 4-6 [But spawning activity was intensive during 12 days] | 5.0 weeks |
Perca fluviatilis | Spawning conditions | Spawning water type | Ponds, lakes, rivers | Stagnant water |
Perca fluviatilis | Spawning conditions | Spawning depth | At the beginning of the spawning period, perch preferentially laid their eggs at a depth of 4 m in lake Geneva, while at the end of the spawning period, a depth of 12 m was preferred by the spawners | 4.0 m |
