| 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 |
| Perca fluviatilis | Female | Absolute fecundity | 17.36-84.24 eggs for fish in a 205310 mm length | 50.8 thousand eggs |
| Perca fluviatilis | Spawning conditions | Spawning season | The spawning period of perch was May in lake Geneva | ['May'] |
| Perca fluviatilis | Female | Length at sexual maturity | In lake Geneva, 87% of perch female became mature during the second year and their size varied from 13 to 20 cm | 87.0 cm |
| Perca fluviatilis | Female | Age at sexual maturity | In lake Geneva, 87% of perch female became mature during the second year | 2.0 year |
