| Species | Development state | Trait | Primary Data | Secondary Data |
| Alburnus alburnus | Female | Absolute fecundity | The estimated of a 5-year-old fish was 6356 with 95% condifidence limits at 5987 and 6776 | 5.0 thousand eggs |
| Alburnus alburnus | Female | Oocyte development | Appereance of three kinds of eggs in the ovaries | No category |
| Alburnus alburnus | Spawning conditions | Spawning period duration | It therefore appears from the samples that the population shed a batch of eggs in early May, and that there was one, possibly two peaks of spawning activity during June | No data |
| Alburnus alburnus | Spawning conditions | Spawning release | Produced two or three batches | Multiple |
| Rutilus rutilus | Female | Age at sexual maturity | The youngest maturing females seen were age 3+ | 3.0 year |
| Rutilus rutilus | Female | Absolute fecundity | Estimated fecundity of a 6-year-old fish was 5157 with 95% confidence limits 4725 and 5631 [In other studies: The average figure for Thames roach is about 5000 or 6000 eggs per fish; caspian semi-migratory roach lay in the range 34,000-51,000, whereas in the following year it had fallen to 19000 to 41000. | 25.5 thousand eggs |
| Rutilus rutilus | Female | Oocyte development | Two categories of eggs could be recognized in active ovaries at all times up to the beginning of spawning | Asynchronous |
| Rutilus rutilus | Male | Age at sexual maturity | A proportion of the males matured at age 2+ | 2.0 years |
| Rutilus rutilus | Spawning conditions | Spawning period duration | Short spawning period | No data |
| Rutilus rutilus | Spawning conditions | Spawning release | Sheld all their eggs in one batch | Multiple |
