Extractive activity in international waters – including fishing, seabed mining, and oil and gas exploitation – should be banned forever, according to top scientists.

The high seas, the vast international waters beyond national jurisdiction, cover 43 per cent of the planet’s surface and two-thirds of its living space. Yet they remain largely unprotected and increasingly threatened by overfishing, climate disruption and the rising interest in deep-sea mining.

A widely debated topic in biology and fisheries sciences is the role of oxygen in the growth of fishes and other water-breathing animals. According to new research, developmental changes in individual fish and experimental errors are the causes of inconsistencies that have erroneously been linked to the Gill Oxygen Limitation Theory (GOLT), developed to explain the influence of oxygen uptake on fish growth.

In the heat of summer in central Greece, the Aristotle University of Thessaloniki hosted the 22nd FishBase and SeaLifeBase Symposium.

Titled “Fishes in Changing Ecosystems,” the two-day event started on September 2, 2024, with a full day dedicated to some of the overarching themes the Sea Around Us team is doing research on.
