| Species | Development state | Trait | Primary Data | Secondary Data |
| Chondrostoma nasus | Egg | Oocyte diameter | The average size of eggs increased from original 1.76 mm | 1.76 mm |
| Chondrostoma nasus | Egg | Egg size after water-hardening | The average size of eggs increased from original 1.76 mm to 2.50 mm, their diameter increasing 1.42 times. Under the conditions of the hatchery at Ochoz, at water temepratures of 6.5 to 6.6°C, this stage lasted condiderably longer, about 6 hours. After that time, the average size of eggs of the same materila attained 2.59 mm and increased still during subsequent days of incubation to 2.92 mm (1.66 times increase) | 1.76 mm |
| Chondrostoma nasus | Egg | Egg adhesiveness | The swelling up of the eggs is accompanied by their becoming very sticky | Adhesive |
| Chondrostoma nasus | Egg | Incubation time | The mean duration of incubation (50% embryos hatched), at the overall mean temperature of 11.12°C was 20 days and 23 hours | 50.0 days |
| Chondrostoma nasus | Egg | Temperature for incubation | 10-17.28°C, temperature tested | 13.64 °C |
| Chondrostoma nasus | Egg | Temperature for incubation | The daily temperatures at incubation varied between 6.5 and 13.6°C, with maximum daily amplitudes of ±1°C. During the rest of the embryonic period until hatching, the water temperature was 12.2 to 14.5°C | 6.5 °C |
| Chondrostoma nasus | Egg | Degree-days for incubation | About 130-160 at 11.6-15°C [From 99.3-231.3, for 10.0-17.28°C] | 145.0 °C * day |
| Chondrostoma nasus | Egg | Degree-days for incubation | 233.1 DD at 11.12°C | 233.1 °C * day |
| Chondrostoma nasus | Larvae | Initial larval size | 7.09-9.81 [Depending on temperature] | 8.45 mm |
| Chondrostoma nasus | Larvae | Larvae behaviour | Although the hatched embryos still spend most of their times lying passively on one side of the bottom of the through, they sometimes rise to the surface and then sink pasively to the bottom again | Demersal |
| Chondrostoma nasus | Larvae | Reaction to light | Their photophobia and thigmoplilia are most marked during this stage. The embryos tend to congregate under scarcity of shelters | Photopositive |
| Chondrostoma nasus | Larvae | Temperature during larval development | Between 12.4 to 15.4°C | 12.4 °C |
| Chondrostoma nasus | Larvae | Full yolk-sac resorption | The yolk sac is present in form of a small remainder which disappears by the end of the stage, i.e. 31 days after insemination or 11-12 days at 14-15°C | 11.5 °C * day |
| Chondrostoma nasus | Larvae | Onset of exogeneous feeding | Starts to ingest food actively at a age of 27 days after insemination (i.e. 7-8 days after hatching at 12.4-14.5°C), having attained a total length of about 12 . The duration is rather short, being about 4 days at water temperature of 14.1-15.4°C | 7.5 °C * day |
| Chondrostoma nasus | Spawning conditions | Spawning season | April in Czech Republic | ['April'] |
| Chondrostoma nasus | Spawning conditions | Spawning substrate | Lithophilous | Lithophils |
