Species | Development state | Trait | Primary Data | Secondary Data |
Chondrostoma nasus | Larvae | Initial larval size | The average body length of newly hatched larvae was 8.22 ± 0.7 mm (TL) | 8.22 mm |
Chondrostoma nasus | Larvae | Temperature during larval development | Larvae were reared at 18-20°C, until 21 days posthhatching | 19.0 °C |
Chondrostoma nasus | Larvae | Full yolk-sac resorption | Endogenous feeding of the nase larvae lasted from hatching until 4 dph, mixed feeding from 4 to 9 dph, and beginning from 9 dph the fish fed exogenously (at 18-20°C) | 19.0 °C * day |
