26.01.2023The Oder's ecosystems have a chance to recover but they need to be supported'If we create the right conditions, aquatic ecosystems quickly recover. Even so, it must be assumed that this process takes years,' says Prof. Piotr Parasiewicz from the Stanisław Sakowicz Inland Fisheries Institute in Olsztyn. The Institute is involved in ichthyological research. A control catch was carried out in autumn 2022 as part of the nationwide monitoring. Nearly 5,500 fish were caught in the Oder River. Almost 30 species were identified. Dominant among them were perch and roach as well as gudgeon and bleak. The researchers also recorded the presence of the protected bitterlings and spined loaches. 'Ichthyological monitoring is only one of the activities,' Professor Parasiewicz emphasises at the beginning of the interview. 'Our Institute continues to study the Oder River ichthyofauna status and is also developing an ecosystem remediation plan. Only through thorough research analysis can rational solutions be created,' the expert adds.

30.12.2022Results of the nationwide ichthyological monitoring 2022. Latest data on the Oder RiverAs part of state environmental monitoring, the Stanisław Sakowicz Inland Fisheries Institute in Olsztyn conducted a study of the fish populations in rivers in Poland. Specialised control fisheries conducted in autumn 2022 also covered the Oder River. A summary of the monitoring is included in the report: Assessment of surface water bodies surface water bodies for ichthyofauna for the year 2022.

10.10.2022What's next for the Oder - Andrzej Szweda-Lewandowski, General Director for Environmental Protection, explainsAccording to a report by the Team for the Situation Arising on the Oder River, the cause of the massive fish die-off in the river was a toxin produced by 'golden algae'. These rare occurring microscopic algae may have found their way into the waters carried by, for example, birds. 'Golden algae' are not only found in marine waters but also inland reservoirs and rivers, generally in industrialised areas with higher salinity of the waters, fish ponds, and others. So far, they have appeared on all continents except for Antarctica.

30.08.2022Report of the Team for the Situation Arising on the Oder River. The basis for further researchScientists have proven that a fast-acting toxin produced by 'golden algae' led to fish deaths. Heavy metals, pesticides or petroleum-based substances did not cause the die-offs. On the other hand, the massive bloom of microalgae was generated by overlapping factors: changes in water parameters, including increased salinity caused by hydrological drought, hot weather raising the water temperature to 27oC and high sunlight, higher than in previous years, which accelerates the growth of algae. These conclusions were drawn on the basis of more than 36,000 surveys carried out.

23.08.2022Polish scientists lead pioneering research. They have isolated the DNA of the ‘golden algae’ toxinsResearchers from the University of Gdańsk have isolated the DNA and RNA of prymnesins, namely the toxins produced by 'golden algae.' The researchers are currently developing a standard that will precisely determine these little-known ichthyotoxins. There are no research standards in this area in the European Union.

18.02.2022Tests of water from the Oder River have indicated the presence of microorganisms – ‘golden algae’On 18 August 2022, Minister of Climate and Environment Anna Moskwa reported on the findings of experts from the Inland Fisheries Institute. They indicated the presence of microorganisms, golden algae, in the water from the Oder River. These are not harmful to humans.
