| Species | Development state | Trait | Primary Data | Secondary Data |
| Acipenser sturio | Larvae | Reaction to light | This is because of the absence of positive phototactism | Photopositive |
| Acipenser sturio | Larvae | Full yolk-sac resorption | The first excretion of the melanin plug occurred at 12 days post hatching + Nauplii were observed in the digestive tract for the first time at 16 dph at a mean weight of 31 mg. // baerii :Thus, confirming that this expulsion was not the consequence of the first feeding as previously reported for A. baerii | 12.0 °C * day |
