12 | Sibling intracohort cannibalism | Cannibalism seems to be apply only to Central and Eastern European regions, not to Western Europe | Present | Deeler and Willemsen, 1964 |
12 | Sibling intracohort cannibalism | In rearing conditions, cannibalism has been observed with individuals 2 to 4 cm long. In natural conditions, the cannibalism is maximal with individuals 1.1-2.0 cm long | Present | Chodorowski, 1975 |
12 | Sibling intracohort cannibalism | Cannibalism could be a big problem | Present | Schlumberger and Proteau, 1993 |
12 | Sibling intracohort cannibalism | This includes the onset of cannbalism due to the size differences bewteen indifviduals of this species. Bi-modality of size frequency distributions is a well-known phenomenon in this species. An earlier start of cannibaslim was observed in pike-perch of smaller size (less than 30 mm) fed in laboratory experiments using artifical diets, however cannibalism ceases at aout 5 cm body length (1.2 g). | Present | Hilge and Steffens, 1996 |
12 | Sibling intracohort cannibalism | The first cannibalistic attacks were observed at 4-6th day after rearing | Present | Mamcarz et al, 1997 |

12 | 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 | Szkudlarek and Zakes, 2007 |

13 | 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 | Ostasweska, 2005 |
14 | Onset of exogeneous feeding | At the age of 2-5 days the larvae start exogeneous feeding | 3.5 °C * day | Lehtonen et al, 1996 |
14 | Onset of exogeneous feeding | 3 days after hatching at 15°C | 3.0 °C * day | Schlumberger and Proteau, 1993 |
14 | 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 | Ostasweska, 2005 |
14 | 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 | Szkudlarek and Zakes, 2007 |
