Species | Development state | Trait | Primary Data | Secondary Data |
Sander vitreus | Larvae | Larvae behaviour | Embryos characteistically suspend themselves at the water surface; vertically, with head up and ventral abdominal surface of the yolk and oil near the surface | Demersal |
Sander vitreus | Larvae | Reaction to light | Fry are photopositive until they reach a length of 32 mm | Photopositive |
Sander vitreus | Larvae | Temperature during larval development | First 9-15 then 21°C | 12.0 °C |
Sander vitreus | Larvae | Sibling intracohort cannibalism | The occurrence of cannibalism is reported from ages 6 to 16 days after hatching (120-214 DD). Population fry can be decimated unless steps are taken to control cannibalism | Present |
Sander vitreus | Larvae | Full yolk-sac resorption | 100-127 | 113.5 °C * day |
Sander vitreus | Larvae | Onset of exogeneous feeding | 100-122 | 111.0 °C * day |
