| Species | Development state | Trait | Primary Data | Secondary Data |
| Carassius auratus | Spawning conditions | Spawning temperature | >17 | 17.0 °C |
| Rutilus rutilus | Female | Oocyte development | Roach is a total spawner with synchronous oocyte development, i.e. roach contain only one stage of developing oocytes, and ovulation is synchronous for all vitellogenic oocytes | No category |
| Rutilus rutilus | Female | Onset of oogenesis | Developed quickly during the autumn, in September. Ovary development proceeded slowly during the winter, increased by 3 in the period from December to February [Roach belong to a group of temperate zone cyprinids that initiates gonad develoment while the temperature and photoperiod are decreasing in autumn. Ovarian development begins in early autum, and then vitellogenesis proceeds slowly throughout winter with the final maturation stages of oocytes and spawning occuring in spring or early winter] Could indicate that the lowest temperature at which roach ovary development occurs is close to 3°C | ['January', 'February', 'March', 'April', 'May', 'June', 'September', 'October', 'November', 'December'] |
| Rutilus rutilus | Female | Intensifying oogenesis activity | The final stages of ovary development occurred rapidly in early spring. Ig increased by 5 in the period from the beginning of April to mid-May | ['April', 'May', 'June'] |
| Rutilus rutilus | Female | Maximum GSI value | Peak at the end of May at 20-23% | 21.5 percent |
| Rutilus rutilus | Female | Resting period | After the spawning period, a quiescent period of gonad activity occurs during the summer because warm temperature (>20°C) and the long hours of daulight block the development of gonads until the end of August | 20.0 months |
| Rutilus rutilus | Spawning conditions | Spawning migration distance | Roach migrate towards deeper water (25-35 m) in winter when water temperature is constant through the water column in deep lakes. Roach migrate towards warmer waters near the surface when a temperature gradient begins to appear again in the spring | 30.0 km |
| Rutilus rutilus | Spawning conditions | Spawning season | Spawn in May or June, depending on the water temperature in Lake Geneva | ['May', 'June'] |
| Rutilus rutilus | Spawning conditions | Spawning period duration | During the first half of the survey period, roach spawned at the end of may or at the beginning of June. The spawning period lasted c. 1 week. During the second half of the survey period, the roach spawning period occurred in mid-May | 1.0 weeks |
| Rutilus rutilus | Spawning conditions | Spawning temperature | 18-20; also described as 18-20; 16; 12; and 10 | 19.0 °C |
| Rutilus rutilus | Spawning conditions | Spawning water type | In lake Geneva, along the embankments | Stagnant water |
| Rutilus rutilus | Spawning conditions | Spawning depth | Near the surface of the water | No data |
| Rutilus rutilus | Spawning conditions | Spawning substrate | In lake Geneva, roach usually spawn on rocks | Lithophils |
| Tinca tinca | Female | Onset of oogenesis | Vitellogenesis begins at the end of winter | ['January', 'February', 'March'] |
| Tinca tinca | Spawning conditions | Spawning temperature | >18 | 18.0 °C |
