Antarctic krill: how did a paperclip-sized crustacean cause a diplomatic row – and why are they so important?
A What happened
The arrest of a Ukrainian scientist by Russia has brought attention to the critical role of Antarctic krill in the Southern Ocean ecosystem. These small crustaceans are essential for larger marine animals, including penguins, whales, and seals, and they significantly contribute to climate regulation by sequestering carbon. In 2023, approximately 500,000 tonnes of krill were harvested, with Norway leading the catch. Conservationists warn that overfishing and climate change pose serious threats to krill populations, which are already under pressure. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) has struggled to implement effective oversight, with only two marine protected areas established since 2009. A coalition of scientists and activists is urging CCAMLR to close the Southern Ocean to krill fishing to prevent ecological collapse, emphasizing the urgent need for sustainable practices.
