St.Gallen SG: Feuerwehr bekämpft Fischsterben

St. Gallen, SG: Fire Department Combats Fish Die-Off The volunteer fire department was deployed on Wednesday (June 24, 2026) to protect fish. Fourteen members artificially sprinkled water at four different ponds to improve the oxygen levels. This measure is similar to the effect of rainwater. It became necessary after the St. Gallen city police received a report on Monday of a large number of dead fish in the Nestweiher pond. By evening, approximately 600 dead fish had already been removed from the pond. Water analysis revealed a lack of oxygen. Experts say that further fish deaths cannot be ruled out in the coming days. Oxygen levels are still critical in some areas. So far, roach have been the most affected fish. Whether their population will need to be supported at a later date remains to be seen.
