Species | Development state | Trait | Primary Data | Secondary Data |
Acipenser baeri | Egg | Egg size after water-hardening | 2.8-4.1 | 3.45 mm |
Acipenser baeri | Egg | Incubation time | 6-7 | 6.5 days |
Acipenser baeri | Larvae | Sibling intracohort cannibalism | present day 9 to 15 post hatching 2-5% mortality | Present |
Acipenser baeri | Larvae | Full yolk-sac resorption | At onset of exogenous feeding (9 days post hatch), yolk sac reserves are not completely depleted from the cardiac stomach, suggesting a period of mixed nutrition. | 9.0 °C * day |
Acipenser baeri | Larvae | Onset of exogeneous feeding | 5-7 days | 6.0 °C * day |
