In August of 2026, the Antarctic krill fishery in the Southern Ocean closed early again — for the second consecutive year. The quota of 620 thousand tons was exhausted well before the usual November, and this event raises concerns about the fragile balance of an entire ecosystem.
Antarctic krill (Euphausia superba) is a tiny crustacean that serves as the foundation of the region's food web. Penguins, whales, seals, fish, and squid depend on it. Without it, the entire Antarctic pyramid of life risks being destabilized, and the consequences could even reach distant oceanic systems.
The early closure is linked to a sharp increase in the fleet and the concentration of vessels in the richest krill areas — near the Antarctic Peninsula and the South Orkney Islands. Norwegian and Chinese companies dominate the catches, and competition among them is intensifying.
The quota of 620 thousand tons was set back in 1991 as a precautionary measure to avoid harming predators. However, fishing is now concentrated precisely in key foraging areas for penguins and whales, which alarms scientists. The exact impact on populations is not yet known, but the precautionary principle demands action now.
Climate change adds pressure: warming is altering the distribution of krill, and fishing compounds these shifts. Scientists note that the combination of the two factors could be more severe than each individually.
Diplomatic disputes in CCAMLR continue. Some countries seek to increase quotas, while others push for new protected areas. No compromise has been reached, and each season brings new catch records.
Krill is used for aquaculture feed, pet food, and dietary supplements. Commercial interest is growing, but behind it lies the question: how sustainably can the foundation of an entire ecosystem be exploited?
The early closure of the fishery is not just a statistic but a signal that even 'strictly regulated' fishing requires more stringent measures for effort distribution and consideration of the needs of wild populations.
