Europe's Summer Drought Kills Fish Farms and Pushes Land Toward Desertification

A prolonged summer of record drought and heat has devastated aquaculture and freshwater ecosystems across central and southeastern Europe, with damage running into the millions of euros. In Hungary, roughly 99% of the country is under severe or extreme drought; nearly 280 metric tons of fish died at 20 farms as 1,588 hectares of ponds dried out, a loss estimated at about $4.2 million, and producers warn restocking could take years. Similar crises are unfolding along a dried-out side channel of the Danube in Serbia, on Slovenia’s Lake Pristava (where crews pumped in 8 million liters of water to stave off mass fish suffocation), and at trout and carp farms in Bosnia, Romania, and the Czech Republic.

The damage compounds year over year. Romanian carp farmers, working on three-to-four-year production cycles, say losses from the 2023 and 2024 droughts are still cascading forward, worsened by water policies that diverted supply to agricultural irrigation. Operators are resorting to emergency measures — cutting feeding to lower oxygen demand, aerating or draining marginal ponds, adding liquid oxygen, and physically relocating stranded fish — while the Great Hungarian Plain faces creeping desertification as vegetation recedes.

Scientists tie the pattern to human-driven climate change, and the recurring, unprepared-for nature of these events is the real signal: this is a structural water-management and climate-adaptation problem, not a one-off bad summer. Governments and producers are now weighing long-term measures to retain water in the landscape rather than rely on the next rainfall.
