Fish slaughter raises fears of environmental disaster in Germany and Poland



Lhe local population is called upon to stay away from the Oder. On this river flowing between Poland and Germany, thousands of fish float lifeless on the Oder River, raising fears of a “disaster” for the environment. These shoals of fish flocking, bellies in the air, to the shores near the town of Schwedt, in eastern Germany, were probably carried by the current from Poland, where the first cases were reported by local residents and fishermen as early as July 28.

German officials, taken by surprise by their massive arrival, accused the Polish authorities of failing to inform them. German Environment Minister Steffi Lemke has demanded an exhaustive investigation to determine the causes of this “environmental disaster”. In Poland, the right-wing populist government has come under fire for not reacting sooner.

Polish Prime Minister Mateusz Morawiecki said on Saturday that he had been informed “August 9 or 10” of the pollution. “Obviously I learned this too late. “At first everyone thought it was just a local problem,” he said on his weekly podcast on Friday. “The scale of the pollution is very large, large enough to say that the Oder will need whole years to return to its natural state,” he acknowledged.

“Deeply shocked”

Standing at the water’s edge, Michel Tautenhahn, Deputy Chief of the Lower Oder Valley National Park, stares in dismay at the river, which forms a natural border between Poland and Germany. “We are on the German side. We have dead fish everywhere,” he told AFP. “I am deeply shocked…I feel like decades of work have been ruined. […] Water is our life,” he says, adding that a host of other aquatic animals, such as mussels, have also succumbed. Fish, “it’s just the tip of the iceberg”, he says.

The Oder has been considered a relatively clean river for many years, supporting around 40 species of fish. Many – some a few centimeters long, others almost 40 centimeters – now float lifelessly down the river. Sometimes we see some of them flapping their tails and turning around with difficulty to try to swim.

“Atypical” death

Authorities believe the fish were likely poisoned. Their death is “atypical”, explains Axel Vogel, Minister of the Environment of the Land of Brandenburg, judging that “tons” of fish have probably already perished. Fish kills are often caused by distorted oxygen levels when the water level is too low, he says. “But we have noticed an increase in the oxygen level for several days, which indicates that a foreign substance has been introduced and caused all this”, according to him.

Tests are underway in Germany to establish the nature of this substance. Authorities have already reported signs of extremely high levels of mercury. Further preliminary tests released on Friday evening revealed an unusually high salinity level. Other results are expected on the possible presence of heavy metals or mercury.

In Poland, the prosecution has been seized of the case, while indignation is growing in the country. The head of government sacked on Friday two water and environmental protection officials, whom he blamed for “action that was too slow”. On Saturday, the Polish police offered a reward of 210,000 euros to find the author of the pollution. On the banks of the Oder in Germany, Mr. Tautenhahn worries about the future. “If it’s mercury, it will stay there for a long time,” he said, recalling that this metal does not disintegrate and could remain for many years in the sediments.
