Katastrofa ekologiczna na Odrze: naukowcy z IGB tropią potencjalnie toksyczne glony

Katastrofa ekologiczna na Odrze wywołuje również wielkie poruszenie wśród naukowców z Instytutu Ekologii Słodkowodnej i Rybactwa Śródlądowego Leibniza (IGB) w Berlinie. IGB od dziesięcioleci prowadzi badania Odry, skupiając się nad ekologią rzeki i zbiorowisk rybnych. Ponadto instytut koordynuje program reintrodukcji jesiotra bałtyckiego w Odrze. Dlatego też IGB rozpoczęło własne dochodzenie; naukowcy podążają tropem silnej toksyny, która może być wytwarzana przez gatunek glonów Prymnesium parvum. Badacze wykryli duże ilości tych glonów w próbkach wody z Odry.

Environmental disaster on the Oder: IGB researchers track potentially toxic algae

The environmental disaster on the Oder river also leaves researchers from the IGB in a great sense of shock. They the are currently tracking down a strong toxin that can be produced by the algae species Prymnesium parvum. Even if this suspicion is confirmed, it is not a natural phenomenon, but definitely a man-made problem.

Sturgeon stocking on the Odra river shaded by concerns

Together with representatives of the Helsinki Commission, the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) released 400 juveniles of Baltic sturgeon (A. oxyrinchus) into the Odra river on 11 May 2022. For those present, it was a touching moment that was also overshadowed by concerns. Despite substantial objections, the Polish government is pushing ahead with the navigation development on the river. The Odra is still one of the last major near-natural rivers in Europe.

One in five fish dies from passing hydroelectric turbines

Hydroelectric turbines put fish at risk of severe injury during passage. To support an informed debate on the sustainability of hydropower, reliable data of turbine-induced fish mortality are pivotal. A team of researchers has now provided a first global analysis. On average, 22.3 percent of all fish passing through turbines got killed or showed severe, potentially lethal injuries.
