### Europe's Summer Drought Leaves Fish Industry in Peril

The relentless summer drought in Europe has reached a critical point, with fish populations in rivers, lakes, and ponds facing an existential threat. The arid conditions have led to the drying up of water bodies, with small boats now resting on cracked ground along the Danube River in Serbia, a stark reminder of the impact on aquatic life.

Northern Serbia has been particularly hard hit, with the Danube's water levels receding to the point where only a few shrinking ponds remain. Fishermen like Dusan Jovanovic are now facing a dire situation. "This is all we have, these two little ponds that are full of juvenile fish," Jovanovic lamented. The water's temperature has soared to over 30 degrees Celsius (86 degrees Fahrenheit), putting the fish at risk of mass mortality.

The drought's impact is not confined to Serbia. It has swept across the region, affecting lakes in Slovenia, fish farms in Bosnia, the Czech Republic, Romania, and Hungary. The fish industry has been hit especially hard, with millions of euros in damage estimated. This, coupled with other challenges such as energy and water supply issues, crop failures, and losses in river traffic, has taken a heavy toll on the region's economy and ecosystems.

In Hungary, around 99% of the country is under severe or extreme drought conditions, according to the national meteorological service. The situation is so dire that desertification, a process where vegetation recedes due to high heat and low rainfall, threatens much of the Great Hungarian Plain. Among the most affected are Hungary's roughly 27,000 hectares of fish ponds. The Agriculture and Food Economy Ministry reported that persistent heat and water shortages have led to the drying out of 1,588 hectares of these ponds, resulting in the deaths of nearly 280 metric tons of fish at 20 farms. The estimated revenue loss from this damage is 1.3 billion forints ($4.2 million).

Romanian fish farmers, particularly those cultivating carp, are also feeling the brunt of the drought. Catalin Platon, president of the ROMFISH National Association of Fish Producers, explained that the effects of severe droughts in 2023 and 2024 are still being felt. Carp production has a three- to four-year production cycle, meaning that losses incurred in previous years are still impacting the industry today.

The repeated droughts have taken a toll on fish farmers across the region. In the Czech Republic, for instance, fishermen are struggling to save their ponds by draining one and diverting its water to save fish in another. The Hungarian Aquaculture and Fisheries Inter-branch Organization reported that this desperate measure has become necessary to preserve what remains of the fish population.

As the region grapples with the consequences of the drought, countries and businesses are now pondering ways to minimize the effects of future extreme weather events. These events are increasingly being linked to human-induced climate change, and the region is under no illusion about the challenges that lie ahead.

The European Union has already taken steps to address the issue, including investing in water management systems and promoting sustainable agricultural practices. However, the scale of the problem demands a coordinated global response to mitigate the effects of climate change and protect the planet's delicate ecosystems.

The fish industry's plight serves as a stark warning of the potential consequences of neglecting the environment. As the region battles the current drought, it must also prepare for the possibility of more frequent and severe weather events in the future. The time to act is now, before the damage becomes irreparable.
