Urgent Call to Protect Atlantic Mackerel Stocks from Overfishing

Recent assessments reveal that the mackerel population in the Northeast Atlantic is on the verge of collapse. This alarming situation has been highlighted by the International Council for the Exploration of the Sea (ICES), which has released new data and scientific recommendations regarding fish stocks.

The World Wildlife Fund (WWF) Austria has issued a strong appeal to coastal nations to adhere to scientific guidelines and take immediate action to halt overfishing. Mackerel, a popular food fish in many regions, including Austria, play a crucial role both ecologically and economically.

According to marine experts, the latest figures from ICES serve as a critical warning. If the current trend continues, the mackerel population could shrink to unsustainable levels, making recovery impossible. The WWF emphasizes that the ongoing failure of responsible states to agree on fishing quotas has exacerbated the situation. Historical data indicates that mackerel stocks in the Northeast Atlantic were once robust, but since 2010, catch levels have exceeded scientific recommendations by an average of approximately 39 percent. Between 2014 and 2025, the population has plummeted by 78 percent, leading to the current crisis.

In response to these alarming trends, the WWF has classified mackerel as 'red' in its seafood guide since April 2025, marking it as not recommended for consumption. The organization stresses the importance of recognizing biological limits for fish stocks. Each year, ICES provides scientific advice regarding fish catch limits within EU waters and adjacent seas, noting that the mackerel stock has fallen below the so-called 'Blim' value, which indicates a biomass limit reference point. When stock levels drop below this threshold, they are considered outside safe biological limits, jeopardizing their ability to recover.

Marine experts warn that failure to respect these biological boundaries could ultimately result in the extinction of mackerel, a situation that would have dire consequences for both marine ecosystems and fishing communities. The WWF urges immediate and coordinated action from all stakeholders involved to ensure the sustainability of mackerel stocks and protect the delicate balance of marine life in the Northeast Atlantic.
