| Species | Development state | Trait | Primary Data | Secondary Data |
| Phoxinus phoxinus | Egg | Oocyte diameter | The largest eggs (1.4 mm diameter) were found in a sample of P. phoxinus from 3 June in which females freely released eggs from the oviduct following gentle pressure on the abdomen. Fish caught at another site the preivous day (2 June) contained smaller eggs (0.87-0.93 mm) which were presumably some days away from being released | 0.9 mm |
| Phoxinus phoxinus | Female | Age at sexual maturity | The minnows reached 50.9 mm fork length by their second birthday, wich was the age of first maturity. The sexes did not differ significantly either in length or numbers in the first three age-classes | 50.9 year |
| Phoxinus phoxinus | Female | Length at sexual maturity | The minnows reached 50.9 mm fork length by their second birthday, wich was the age of first maturity. The sexes did not differ significantly either in length or numbers in the first three age-classes | 50.9 cm |
| Phoxinus phoxinus | Female | Absolute fecundity | In May the mean standard fecundity was 623.6 (±112) | 623.6 thousand eggs |
| Phoxinus phoxinus | Female | Onset of oogenesis | September | ['September'] |
| Phoxinus phoxinus | Female | Maximum GSI value | Range between 12-14 during May-June | 13.0 percent |
| Phoxinus phoxinus | Female | Resting period | Between 3 June and 15 July there was a sharp drop in total condition princiapply beacause of a fall in GSI. This decline in GSI continued until late August | 3.0 months |
| Phoxinus phoxinus | Male | Onset of spermatogenesis | September-October. By October, GSI had risen to 1.23% | ['September', 'October'] |
| Phoxinus phoxinus | Male | Maximum GSI value | 4.65% [18-20 May] | 19.0 percent |
| Phoxinus phoxinus | Spawning conditions | Spawning period duration | Some females still contained ripe eggs on 15 July, 50 days after the first spent females had been captured | 15.0 weeks |
| Phoxinus phoxinus | Spawning conditions | Spawning release | Analysis of the changes in egg numbers in the gonads over this period indicates that each female ripens and sheds several batches of eggs over the spawning season. Spawn at least four successive batches of eggs | Multiple |
| Phoxinus phoxinus | Spawning conditions | Parity | Few males survived to their fourth birthday and the oldest fish, aged five years, was a female | No category |
