Climate change threatens fish: VetMedtalk clarifies on June 24th!

On June 24, 2025, experts will discuss the effects of climate change on freshwater habitats and their animal residents as part of the VetMedTalk online, especially on fish. The event, which begins at 6:30 p.m., is moderated by Bernhard Weingartner and has the goal of clarifying the public about the challenges and changes in fish health and fish stands. Experts such as Daniela Achleitner, Astrid Holzer and Gunther Vogl illuminate the dramatic changes in animal and plant populations in waters as well as the consequences of flood disasters to water and food supply in order to initiate changes in the sense of the sustainable development goals (SDGS) of the United Nations. According to ots.at, the understanding of the coherent ecosystems is of central importance.

climate change not only is a challenge for freshwater habitats, but also influences the sea ecosystems worldwide. Oceans regulate the world climate, produce a large part of the earth's oxygen and absorb carbon dioxide. Millions of people are dependent on the oceans as a livelihood. An analysis of the wwf shows that increasing carbon dioxide content and higher temperatures lead to warmer and acidic water, which has serious consequences for fishing. According to forecasts, almost the entire coral reefs could die by the end of the century, which not only endangers the marine ecosystem, but also the little fishermen that are dependent on these reefs.

measures to adapt to climate change

In order to counter the challenges of climate change, sustainable fishing industry is essential. The adaptation strategy includes, among other things, the consideration of future climate changes in fishing quotas and target fish species. The Federal Environment Agency emphasizes that measures such as fishing shear times and more selective fishing methods are necessary to To increase resilience of sea ecosystems. In addition, specifications for mesh sizes should help protect young animals and unwanted species.

The adaptation of fishing to the challenges of climate change also includes the development of sustainable management plans. These plans must be checked and adapted regularly to optimize fishing quotas, gentle times and the protection of non -targeted species. In addition, the need for more effective monitoring of fishing and corresponding sanctions in the event of violations are pointed out.

A look into the future

The forecasts clearly show that global warming has significant effects on fish stocks and global food supply. A degree Celsius warming could reduce the global fishing potential by over 3 million tons, especially in developing countries a reduction of 50% of the fishing quantities by 2050 could be the standard. The challenge is to motivate all actors involved in fishing management for action, since inactivity can lead to food shortages.
