Species | Development state | Trait | Primary Data | Secondary Data |
Scaphirhynchus platorynchus | Larvae | Initial larval size | mean 14, range 14-16 | 15.0 mm |
Scaphirhynchus platorynchus | Larvae | Onset of exogeneous feeding | development into larvae (defined as first feeding interval) happens at 72-78 Degree-Days on day 4 | 75.0 °C * day |
Scaphirhynchus platorynchus | Larvae | Reaction to light | photopositive 1-10 days, photonegative after 11 days | Photopositive |
Scaphirhynchus platorynchus | Larvae | Larvae behaviour | diurnal migration 0-4 days; switch to nocturnal later in development | Demersal |
Scaphirhynchus platorynchus | Larvae | Onset of exogeneous feeding | 4 days post hatch (72-78 Degree-Days) | 75.0 °C * day |
Scaphirhynchus albus | Larvae | Initial larval size | mean 14, range 14-16 | 15.0 mm |
Scaphirhynchus albus | Larvae | Reaction to light | photopositive 1-10 days, photonegative after 11 days | Photopositive |
Scaphirhynchus albus | Larvae | Onset of exogeneous feeding | development into larvae (defined as first feeding interval) happens at 79 Degree-Days on day 4 | 79.0 °C * day |
Scaphirhynchus albus | Larvae | Larvae behaviour | pallid sturgeon remained diurnal in their migration patterns | Demersal |
Scaphirhynchus albus | Larvae | Larvae behaviour | Pelagic behavior observed in days 0-8 post hatch, and benthic behavior observed in 8+ days post hatch | Pelagic |
