Devastating Fish Kill Caused by Oxygen Depletion

Heavy rainfall triggers a massive fish kill in rivers across Ammerland and East Frisia, resulting in the recovery of 6 tons of dead fish by fishing associations. Biologist Jens Salva attributes the tragedy to oxygen deprivation, exacerbated by rising temperatures.

A similar incident occurred in 2023 in neighboring districts. The rivers Leda, Aper Tief, and Jümme are affected, with catfish, eels, bream, and zander among the casualties.

Oxygen levels as low as 2mg/l were recorded, with relief expected at 4mg/l. Efforts to salvage the carcasses involve fishing groups, as authorities monitor the situation closely.

The complexity of the issue suggests multiple contributing factors, including the impact of intense rainfall events.
