According to their own statements, the Polish fire brigade has so far recovered almost 160 tons of dead fish from the Oder and a smaller river. A total of 158 tons, said the spokeswoman for the fire department headquarters on Saturday of the German Press Agency. The majority of this is accounted for by the dead fish from the Oder.
According to earlier information from the Ministry of the Environment, at least 36 tons were recovered in Brandenburg.
The small river in Poland is the Ner, which has its source south of Lodz and flows into the Warta. He has no connection to the Oder. Dead fish have also been floating in the Ner for a few days. The cause has not yet been clarified.
In the past few days, masses of dead fish have been discovered and collected in the Oder on the Polish and German sides.
Scientists say a toxic species of algae could be a key factor in fish kills. But that has not yet been proven. Other substances are currently being investigated.
