Elbefische werden in Geesthacht aufgehalten P6160047

Bild oben: Aktuell ist der Fischpass am Südufer für Fische gesperrt

Seit dem Spätsommer 2019 ist die Fischwanderung deutlich verschlechtert. Grund dafür ist das die Wehranlage die auch für den Straßenverkehr genutzt wird derart gravierende Mängel aufweist das weitreichende Sicherungsmaßnahemen ergriffen werden mussten.  Diese Maßnahmen hahen dazu geführt dass der Fischpass am linken Ufer verfüllt wurde, also für die Fischwanderung komplett ausfällt. Der rechte Fischpass  wurde zunächst seiner Lockströmung beraubt und später behelfsmässig durch eine Rohrinstallation wieder installiert.

Hydropower Station at Meinersen turns into deadly eel-trap again

PFNX1184

Hydropower Stations in rivers are very often responsible for massive damages done to fishes.

Fish species being dependent on migration to complete their life cycles are theratened or even extinct. 

The reasons will be shown here in a series of short videoclips.

This clip here about a hydropower station at Meinersen on River Oker in Lower Saxony shows what happens unfortunately all the time when European Eel start their journey to their spawning habitats in the Sargasso Sea at the Gulf of Mexico: Even before the journey has really started, it is stopped here at this migration obstacle and many eel end up as flotsam in the container of the grid cleaning device. On the way to the Sea there are many hydropower stations... Please see the video here...

A lot of the water has been led over the weir but that didn't prevent the Eels to take their way into the hydropower station.

On 5.2.2021 again eel were trapped in the dead end hydropower following the high water levels. At very high water levels eel gathered as often before in front of the grid of the hydropower station.  This happend although a lot of water was channeled around the hydropower station.

The bypass directly at the grid has not been supplied with water. So the eels were pressed against the grid again and again.

Bypass pipe on 5.2.2021 without water and therefore useless!
