Fish protection

For days now there is plenty work at a new gutter that will lead the fish coming from our coolingwaterfilters back to the sea in a smooth way...
Until now the fish is falling from about 6 meters height back into the water, causing death for most of them. At low tide the fish that survived could not reach the sea again and they died eventually....
The seagulls don't mind; they just have to open their beak and the fish runs in....

In the near future the fish will be lead towards the outer side of the breakwater.
The last part of the gutter has to be laid onto the beam.
At the end there still are some problems lifting the big stones of the breakwater.
I hope this will work....
