A study by the French Research Institute for the Exploitation of the Sea (Ifremer) reveals that almost half of the fish sold in France are from unsustainable populations, indicating a persistent problem of overfishing. The country is still far from reaching the EU's 100% sustainable fishing target. The report also found that 20% of species sold in French markets, such as mackerel and sardines, are overfished. Clara Ulrich, Ifremer's fisheries expertise coordinator, stressed the importance of understanding the factors affecting fish egg and larvae development, especially in the face of climate change.
