“After further investigations, the Inland Fisheries Institute in Olsztyn detected rare microorganisms, the so-called golden algae, in water samples from the Oder River,” Anna Moskwa said on Thursday. Algal blooms could produce toxins that killed fish and clams, but were not considered harmful to humans, he said. German municipalities have banned swimming and fishing in the Oder after masses of dead fish and molluscs were found floating on the water’s surface and washed up on the banks of the 840km-long river, which stretches from the Czech Republic to the Baltic Sea along the border between Germany and Poland. Since last Friday, Polish firefighters have collected more than 100 tonnes of dead fish from the Oder, with German Environment Minister Steffi Lemke reporting around 35 tonnes of dead fish on her soil. Scientists tried to find an explanation for the extinction. Early reports of elevated mercury levels in the waters of the Oder were later found to be misleading.

Water samples were sent to laboratories in the Czech Republic, the Netherlands and Britain in the hope of finding the cause. Golden seaweed (Prymnesium parvum) is usually found in brackish waters where rivers meet the sea, but is known to spread further inland when there are high levels of salinity in the water. “This type of algae requires elevated levels of salt water that do not occur naturally in the affected area of ​​the Oder,” said Jan Köhler of the Leibniz Institute for Freshwater Ecology and Inland Fisheries in Berlin. Polish officials investigated whether particularly higher concentrations of pollutants and salinity could be linked to climate change, with extremely high temperatures across Europe in recent weeks leading to more water evaporating from inland waters. Mineral fertilizers seeping into the river from adjacent farmland also have the potential to cause massive algal blooms, the scientists said. A chemical spill was another case being investigated, with Poland offering a reward of 1 million zlotys or €210,000 (£180,000) for anyone who could “help find those responsible for this environmental disaster”.
