Species | Development state | Trait | Primary Data | Secondary Data |
Sander lucioperca | Larvae | Initial larval size | Total body length of newly hatched larvae was 5.04 +/- 0.05 mm | 5.04 mm |
Sander lucioperca | Larvae | Temperature during larval development | The larvae were reared at constant water temperature of 20°C, until the 30th post hatching | 20.0 °C |
Sander lucioperca | Larvae | Full yolk-sac resorption | The end of endogenous feeding of pike-perch larvae reared at 20°C took place at the same time as macroscopic yolk resorption, on the 6 day post hatching. The remaing traces of yolk nutrients visible under the microscope were absorbed until the 17 day of life | 20.0 °C * day |
Sander lucioperca | Larvae | Onset of exogeneous feeding | The period of endogeneous feeding of the pike-perch lasted until the 6th day post hatching, mixed endo-exogenous feeding occurred from the 6th to the 12th day, and from the 17th day on the fish were exclusively fed exogenous feeding | 6.0 °C * day |
