| Species | Development state | Trait | Primary Data | Secondary Data |
| Leuciscus leuciscus | Egg | Oocyte diameter | Diameter means range from 1.34 to 1.56 [Unfertilized eggs] | 1.34 mm |
| Leuciscus leuciscus | Egg | Incubation time | Fertilization to larvae (2-4 days after hatching): 26-32 days (mostly 30) at 10°C | 3.0 days |
| Leuciscus leuciscus | Egg | Temperature for incubation | Incubated at a constant 10°C in chalk spring water | 10.0 °C |
| Leuciscus leuciscus | Larvae | Initial larval size | Means range from 8.24 to 9.38, for larvae 2 to 4 days old | 8.24 mm |
| Leuciscus leuciscus | Female | Age at sexual maturity | Both sex reach sexual maturity after four years growth, although some fast-growing individuals may do so after three years | 4.0 year |
| Leuciscus leuciscus | Female | Absolute fecundity | 5.973-8.714 for a female 200 mm | 7.34 thousand eggs |
| Leuciscus leuciscus | Male | Age at sexual maturity | Both sex reach sexual maturity after four years growth, although some fast-growing individuals may do so after three years | 4.0 years |
| Leuciscus leuciscus | Spawning conditions | Spawning season | Between late February and early April | ['February', 'April'] |
| Leuciscus leuciscus | Spawning conditions | Spawning period duration | Spawn over a two or three week period | No data |
| Leuciscus leuciscus | Spawning conditions | Spawning water type | Fast flowinf rivers and streams | No category |
| Leuciscus leuciscus | Spawning conditions | Spawning substrate | Gravel spawner | Lithophils |
| Leuciscus leuciscus | Spawning conditions | Spawning release | Release one batch of egg | Multiple |
| Leuciscus leuciscus | Spawning conditions | Parity | Release one batch of eggs annually for up to seven successive years. There was no evidence that any female had a rest year from spawning once they were mature | No category |
