The Antarctic krill season is already over, and it is only August.
On August 12 the fishery in the Southern Ocean’s Area 48 hit its 620,000-metric-ton “trigger level” and closed, more than three months before the usual November end date. It is the second year in a row the cap has been reached that early. In 2025 the fishery shut on August 1. Scientists attending the Scientific Committee on Antarctic Research meeting in Oslo, held August 10–14, confirmed the 2026 closure.
Krill look like small shrimp and sit at the base of the Antarctic food web. Penguins, seals, whales, seabirds, fish, and squid all depend on them. Commercial boats catch them for aquaculture feed, pet food, and omega-3 supplements. The 620,000-ton limit, set by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) in 1991, was meant as a precaution. A later rule split that catch across four sub-areas so boats would not vacuum the same productive pockets year after year. That spatial measure expired in 2024 and has not been replaced.
Without those regional caps, the fleet has crowded into the richest water: the Bransfield and Gerlache straits off the Antarctic Peninsula and northwest of the South Orkney Islands, according to Global Fishing Watch tracking cited by researchers. Simeon Hill of the British Antarctic Survey told Mongabay the 620,000-ton limit is considered to have “minimal consequences” only if catches are not concentrated in penguin foraging grounds. “We are now seeing unprecedented levels of catch concentration,” he said.
The industry argues the early closure proves the system works: when the trigger is hit, boats stop. Norwegian company Aker QRILL, a major harvester, has left the grounds. Norway and China take the bulk of the catch. Conservation groups and several scientists want binding spatial limits restored when CCAMLR meets in October, along with a marine protected area proposed by Argentina and Chile that has sat without consensus for years.
