| Species | Development state | Trait | Primary Data | Secondary Data |
| Rutilus rutilus | Egg | Temperature for incubation | Experimental studies have shown that a constant 9°C forms a critical temperature minimum for the development of roach embryos | 9.0 °C |
| Rutilus rutilus | Spawning conditions | Spawning season | In the Baltic Sea, roach spawn in early May after the ice breakup | ['May'] |
| Rutilus rutilus | Spawning conditions | Spawning water type | Shallow, sheltered, and vegetated shores are important as spawning and larval areas for roach in lakes | Stagnant water |
