| Species | Development state | Trait | Primary Data | Secondary Data |
| Acipenser sturio | Egg | Oocyte diameter | The pigmented ovarian follicles varied greatly from 2.4 to 3.4 mm in diameter without any relationship with the weight of the females | 3.4 mm |
| Acipenser sturio | Egg | Egg size after water-hardening | The range in size of the ovarian follicles should include to the largest pigmented eggs and the small white eggs of less than 0.5 to 0.6 mm in diameter. Intermediate sized, partially pigmented follicles reveal incomplete vitellogenesis, while a marble appearance indicates over maturation | 0.6 mm |
| Acipenser sturio | Egg | Temperature for incubation | water system at 17 – 18 °C are the procedures currently used for sturgeon | 18.0 °C |
| Acipenser sturio | Egg | Degree-days for incubation | 17±0,5°C/100-120 days, (but publication with induced hormonal treatment) | 17.0 °C * day |
| Acipenser sturio | Larvae | Reaction to light | Larvae are not photosensitive during the two days after hatching | Photopositive |
