| Species | Development state | Trait | Primary Data | Secondary Data |
| Silurus glanis | Egg | Egg adhesiveness | After fertilization eggs were tansferred to hatching glasses where they stick to the wall and slightly to each other | Adhesive |
| Silurus glanis | Egg | Degree-days for incubation | Hatching takes place after 60-70 day°C | 65.0 °C * day |
| Silurus glanis | Larvae | Larvae behaviour | To start with the yellow and helpless larvae lay at the bottom of the boxes. On the 2nd and 3rd day, as they became greyish, they gathered in the darker corner | Demersal |
| Silurus glanis | Larvae | Temperature during larval development | 22-26 | 24.0 °C |
| Silurus glanis | Larvae | Onset of exogeneous feeding | After their first feeding (5-7 days old) at temperature of 22-26°C | 6.0 °C * day |
| Silurus glanis | Spawning conditions | Spawning season | Spawning lasted from the beginning of May to the end of the third week in June | ['May', 'June'] |
| Silurus glanis | Spawning conditions | Spawning temperature | Reared at 23-24°C | 23.5 °C |
| Silurus glanis | Spawning conditions | Mating system | The aggressiveness of both sexes increase during the spanwing season and heavy injuries occur even during the normal spawning process. Such injuries may later be the cause of death | No category |
