BR Program shows: Eco hydropower can't answer claim of fishfriendliness

WKA Luft 

A report of Bavarian Broadcasting (BR) shows that hydropower stations in rivers having been built with a special focus on fish protection are if at all less harmful but never at all fish friendly. The report presents the results of a scientific investigation of the Technical University of Munich (TUM) in a compact and concise manner on one out of nine hydropower stations that were supposed to be specially fish friendly. Please find the report here... 





new findings: Salmon migrate longer distances At Sea

Pop up tagged Kelt

A current scientific study shows that Atlantic Salmon migrate longer distances at Sea than assumed so far. 204 Salmon from Norway, Denmark, Ireland, Spain and Greenland have been equipped with so called "Popup-Tag's" after spawning in the period from 2008 to 2014. These tags record the migration route of the fish and detach from the fish after a certain time. After surfacing they send the recorded data to a satellite.  148 individual fish that were tagged in this way delivered data for the study.

While Spanish and Irish Salmon moved to rather southernly areas of the Atlantic the Salmon of Danish Rivers swam up to Greenland and even further North in the vicinity of Barents Sea. There are areas at the east coast of Greenland where different stocks swim together at certain seasons (mixed stocks).

survey on distribution of pink Salmon

In 2017 an increasing number of Pink Salmon (Oncorhynchus gorbuscha) were caught in the North Atlantic and partly also in Germany. This Pacific salmon specieshas been set out in the fifties in the area of the Kola peninsula in Northern Russia.  It is still unkown why this species starts to spread along the entire European Atlantic coast since 2017.  A scientific study should help to answer this question.

If you catch a pink salmon in European water, please report to:

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.


Bild oben: So sah es vor der Verfüllung am Südufer für Fische aus.

„Wasserwerke töten Fische!“ 

... headlined Sundays BILD live news channel meaning hydropower stations in rivers kill fish.

Our video about the Eel issue at Meinersen hydropower station found its way over the German Angling Associoation (DAFV) right into Sundays live program of BILD directly after we had published it on our YouTube Channel.

Showing parts of the mentioned video Stefan Ludwig of "Wanderfische ohne Grenzen" gave a live interview about the issue.

Please find a recording of the program  here .

"STOP shredding millions of fish!"

...headlines the German "BILD-Zeitung" today.

What happens regularily at the hydropower station in Meinersen has its share in this.

Reason for the article is a press release of the DAFV (German Angling Association) that is currently being prepared and takes a clear stance on hydropower.

Please take a look at the online article:

Hydropower Station at Meinersen turns into deadly eel-trap again


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!
