Species | Development state | Trait | Primary Data | Secondary Data |
Leuciscus cephalus | Spawning conditions | Spawning substrate | Stony bottom | Lithophils |
Leuciscus cephalus | Spawning conditions | Spawning temperature | In 1995, spawning took place in a rapid increase of water temprature from 13 to 21°C. In 1995, the temperature remained constant at 11-14°c during the first spawning | 12.5 °C |
Leuciscus cephalus | Spawning conditions | Spawning water type | Located near erosion banks or in shallow upstream of a bridge. The current speed near the spawning substratum ranged between 0.15 to 0.35 m/s | Flowing or turbulent water |
Leuciscus cephalus | Spawning conditions | Spawning depth | The water depth varied between 0.1-10 | 5.05 m |
Aspius aspius | Female | Female sexual dimorphism | Sex was not determined, as this was impossible without harming the fish, especially in the post-spawing season | Absent |
Aspius aspius | Spawning conditions | Spawning migration distance | The migratory behaviour of asp was highly variable, 34 asp observed for more than 1 year lived in home ranges of 1 to > 100 stream kilometres mostly near their capture site. Longest observed migratrion from summer habitat in the Tidal Elbe back to the spawning ground in the middle of Elbe was 166 skm [To date, long upstream migrations (>50 km) from the lower river section are seldom observed] | 34.0 km |
Leuciscus cephalus | Spawning conditions | Spawning migration distance | The distance of spawning migration varied between c. 100m and 16 km | 100.0 km |
Aspius aspius | Female | Onset of oogenesis | The maturation of gonads is synchronous and complete in the previous autumn | ['October', 'November', 'December'] |
Leuciscus idus | Female | Onset of oogenesis | Maturation of gonads is synchrnous and complete in the previous autumn | ['October', 'November', 'December'] |
Leuciscus leuciscus | Female | Onset of oogenesis | Maturation of gonads is synchronous and complete in the previous autumn | ['October', 'November', 'December'] |
Rutilus rutilus | Female | Onset of oogenesis | Maturation of gonads is synchronous and complete in the previous autumn | ['October', 'November', 'December'] |
Blicca bjoerkna | Female | Intensifying oogenesis activity | Most stages of gonad maturation take place in spring | ['April', 'May', 'June'] |
Abramis brama | Female | Intensifying oogenesis activity | Most stages of gonad maturation take place in spring | ['April', 'May', 'June'] |
Leuciscus cephalus | Spawning conditions | Spawning migration period | In both years, most chub started spawning migrations on 21 to 22 May. Chub stayed at or near (distance <50m) the spanwing grounds for 1 to 6 days and returned to their original home sites afterward. In both years, 44 chub strated their second spawning migration on 17 or 18 June mainly to the spawning grounds as in May. By 20 June, all chub were at spoawning grounds. After having spect 1 to 7 days on spawning grounds, chub migrated back to their individual home ranges and stayed there during the postspawning season up to the end of the trackning observations. In 1995, first spawning migration strated after a period of decreased in water tmeperature from 14 to 12°C. In 1996, weter temperature increased from 11 to 14°C beforte the first spawning | ['May', 'June'] |
Aspius aspius | Spawning conditions | Spawning season | Late March/April | ['April', 'March'] |
Leuciscus idus | Spawning conditions | Spawning season | Late winter or early spring | ['April', 'March', 'January', 'May', 'June', 'February'] |
Leuciscus leuciscus | Spawning conditions | Spawning season | Late winter or early spring | ['April', 'March', 'January', 'May', 'June', 'February'] |
Rutilus rutilus | Spawning conditions | Spawning season | Late winter or early spring | ['April', 'March', 'January', 'May', 'June', 'February'] |
Aspius aspius | Spawning conditions | Homing | Tendendy to return to the same spawning ground (reproductive homing) | Present |
Leuciscus cephalus | Spawning conditions | Homing | Tendendy to return to the same spawning ground (reproductive homing) | Present |
Leuciscus leuciscus | Spawning conditions | Homing | Tendendy to return to the same spawning ground (reproductive homing) | Present |
Rutilus rutilus | Spawning conditions | Homing | Tendendy to return to the same spawning ground (reproductive homing) | Present |
Blicca bjoerkna | Spawning conditions | Spawning release | Multiple spawner, but in several years and different water bodies it spawn only once per breeding season | Mutliple |
Abramis brama | Spawning conditions | Spawning release | In most cases, spawns once per breeding season, but it is known to spawn twice or three times especially in southern water bodies | No category |
