Oxygen depletion kills 200 carp in Belgian nature reserve amid low water

About 200 dead carp and small fish were found floating in Blokkersdijk nature reserve in Beveren-Kruibeke-Zwijndrecht, Belgium. Natuurpunt Waasland attributes the deaths to oxygen depletion caused by warm, low water levels. The carcasses are being left in place, with low botulism risk, but volunteers are monitoring. This is a local environmental incident reflecting broader climate-related water stress.
