| Species | Development state | Trait | Primary Data | Secondary Data |
| Rutilus rutilus | Egg | Oocyte diameter | 0.62-1.09 [Vitellogenic egg], but vary between 1.0-2.1 for other areas in Europe but not specified | 0.85 mm |
| Rutilus rutilus | Female | Absolute fecundity | 7-19 [log F = - 4.42 + 3.74 log FL, with FL is the fork length in mm], [Vary between 4-50 in different ears in Europe for a standard female of 170 mm in FL] | 13.0 thousand eggs |
| Rutilus rutilus | Female | Oocyte development | Synchronous ovogenesis | Synchronous |
| Rutilus rutilus | Spawning conditions | Spawning season | May | ['May'] |
| Rutilus rutilus | Spawning conditions | Spawning period duration | Short | No data |
| Rutilus rutilus | Spawning conditions | Spawning water type | Rivers, small tributaries of lakes | Stagnant water |
| Rutilus rutilus | Spawning conditions | Spawning release | Spawns only one batch of eggs per season | Multiple |
| Scardinius erythrophthalmus | Egg | Oocyte diameter | 0.54-0.88 [Vitellogenic egg] | 0.71 mm |
| Scardinius erythrophthalmus | Female | Absolute fecundity | 15-54 for this study | 34.5 thousand eggs |
| Scardinius erythrophthalmus | Female | Oocyte development | Synchronous ovogenesis but in other areas asynchronous ovogenesis | Asynchronous |
| Scardinius erythrophthalmus | Spawning conditions | Spawning season | First two weeks of May | ['May'] |
| Scardinius erythrophthalmus | Spawning conditions | Spawning period duration | 2 but in other areas much longer several months | 2.0 weeks |
| Scardinius erythrophthalmus | Spawning conditions | Spawning water type | River, reservoir, lakes | Stagnant water |
| Scardinius erythrophthalmus | Spawning conditions | Spawning release | Monospawner fish but in other areas where female shed the eggs over several months | Multiple |
| Scardinius erythrophthalmus | Spawning conditions | Parity | Iteroparous | Iteroparous |
| Lepomis gibbosus | Egg | Oocyte diameter | 0.8-1.8 [Vitellogenic egg] | 1.3 mm |
| Lepomis gibbosus | Female | Absolute fecundity | 5-10 [log F=-0.59+2.16logFL, FL is the fork length in mm] | 7.5 thousand eggs |
| Lepomis gibbosus | Female | Oocyte development | Asynchronous ovogenesis [In general, the ovaries of the females contained three kinds of oocytes] | Asynchronous |
| Lepomis gibbosus | Spawning conditions | Spawning season | From mid-May to Mid-August | ['May', 'June', 'July', 'August'] |
| Lepomis gibbosus | Spawning conditions | Spawning period duration | 12 [From mid-May to Mid-August] | 12.0 weeks |
| Lepomis gibbosus | Spawning conditions | Spawning release | Multiple spawner fish, each female spawns repeatedly over several months [Spawn several batches of eggs, three times or more at intervals of 20-30 days] | Multiple |
