Species | Development state | Trait | Primary Data | Secondary Data |
Sander lucioperca | Egg | Temperature for incubation | The eggs were incubated in Weiss jars at 17 +/- 1.0°C until hatching | 17.0 °C |
Sander lucioperca | Egg | Degree-days for incubation | About 80 | 80.0 °C * day |
Sander lucioperca | Larvae | Sibling intracohort cannibalism | Mortality at all densities was mainly caused by cannibalism II type behaviour (27-35% of total). The first signs of cannibalism were observed in larvae measuring 15 mm in total length, and it increased after the larvae had exceeded 20 mm; consequently, it occurred primarily during the period when they fed exclusively on artificial feed | Present |
Sander lucioperca | Larvae | Onset of exogeneous feeding | 4-18 dph, corresponding to the period extending from the beginning of exogenous feeding to the end of swim bladder inflation. Feedinf started in the final stages of the absorption of the yolk sac (about 4 days post hatching). Feeding with Artemia nauplii started 1 day later | 11.0 °C * day |
Sander lucioperca | Larvae | Onset of exogeneous feeding | 4 days 20 C | 4.0 °C * day |
