Lake Geneva's Fish Face Threatened by Warming Waters Experts Warn of 'Historic Record' in Oxygen Levels

<br><br>**Title** Lake Geneva's Fish Face Threatened by Warming Waters Experts Warn of 'Historic Record' in Oxygen Levels<br><br>As professionals in the field of startup mentoring, we're no strangers to navigating uncertainty and adapting to changing conditions. In this blog post, we'll explore a pressing issue that affects not only Lake Geneva but also our planet as a whole.<br><br>**The State of the Lake**<br><br>Lake Geneva, Western Europe's largest lake, is facing an unprecedented threat to its aquatic ecosystems. According to Nicole Gallina, corporate secretary of the International Commission for the Protection of the Waters of Lake Geneva (CIPEL), the lake's temperature is increasing at an alarming rate, leading to a lack of oxygen in its depths.<br><br>**The Impact on Fish**<br><br>This lack of oxygen has devastating consequences for the fish that call Lake Geneva home. Typically, the lake's natural winter mixing process ensures that oxygen reaches the lower levels, but with global warming, this process is becoming increasingly rare. As Viet Tran-Khac, laboratory manager at France's National Research Institute for Agriculture, Food and the Environment, explains, If there is less and less oxygen in the water, there is less and less viable space for living organisms.<br><br>**The Future of Fish**<br><br>But it's not just the fish that are at risk. The entire ecosystem of Lake Geneva is under threat. Phytoplankton plants, which are eaten by zooplankton organisms, are struggling to grow due to the lack of oxygen. This has a ripple effect throughout the food chain, impacting the growth and survival of fish species like Arctic char, fera, and others.<br><br>**Adapting to Change**<br><br>To adapt to these changing conditions, Alexandre Fayet, president of the Swiss inter-cantonal association of professional Lake Geneva fishermen, is diversifying their fishing practices. We are trying to commercialise fish that like warmer and less oxygenated waters, such as carp, tench, and bream, he explains.<br><br>**The Role of Research**<br><br>LeXPLORE, a floating scientific platform, has been conducting research on Lake Geneva since 2019. According to project manager Natacha Tofield-Pasche, the platform is studying 44 different parameters down to a depth of 110 meters. This research provides crucial insights into the impacts of global warming and extreme events like floods on Lake Geneva's ecosystems.<br><br>**Conclusion**<br><br>The story of Lake Geneva's fish serves as a powerful reminder of the multifarious challenges facing our planet. By exploring new perspectives and approaches, we can work together to build a more resilient future for all – including the fish that call Lake Geneva home. As professionals in the field of startup mentoring, we're no strangers to navigating uncertainty and adapting to changing conditions. It's crucial that we continue to learn from each other's experiences and work towards a sustainable future.<br><br>**Keywords** Lake Geneva, global warming, aquatic ecosystems, fish species, phytoplankton plants, zooplankton organisms
