The lurid find of thousands of dead eels near Termunten is a great puzzle. The fish died massively unexpected crawled out of the water and around the Breebaartpolder at the Groningen.
The countless animal carcasses were this week found to on the way past the Dollard dijk, left the landscape of Groningen worried administrator know. Possible had the animals ‘ stuffy ‘ by oxygen deprivation yet and they tried to get away.
It seems that there are no other fish species have gone dead. In the region despite the heat period the fishing mortality was not remarkably high, so it seemed at least until Wednesday. Went here and fish death in garden ponds, but not much in nature reserves. Also may have heavy rainfall there what to do with it.
Blue-green algae
Employees of the water board Hunze and AA’s and the volunteers of the Groninger landscape now, however, the nasty task had pockets full of dead eels on to have to clean up. The water Board has at the same time water samples taken for further research into the mystery.
The Groningen polder has a limited tide of thirty centimeters, since there is an opening through a diver in the dike was made to make that possible. Glass eel in the water is turned off.
Dry out
The famous eel fisherman Gaele Palmer from salt camp has the last period just barely dead eel seen in its fishing waters, elsewhere in the province of Groningen at the Lauwersmeer area. ,, I have this period yet just two hundred kilograms of eels caught. ”
Of such a huge mortality as now even has an experienced fisherman, as Palmer never heard before. He is also curious about what is going on. ,, For blue-green algae, they are not very sensitive. It seems that the eels ‘ stuffy ‘ have had it there by the warm time. But once on the side they can still dry out if their protective mucus dries up by the cold wind ‘ ‘, he suggests.
The water Board went there Thursday after a preliminary examination that the animals indeed ‘ stuffy ‘ were looking for oxygen rich water. Their swimming water turned out to be hit by algae growth deteriorated. The heat was on shore, however, fatal, before they could swim safely back in better water. Cool weather there will probably ensure that the striking eel drama does not repeat.
