Antarctica – Environmental organizations have filed formal objections to the Marine Stewardship Council’s draft recommendation to renew sustainability certification for krill fishing in the Southern Ocean, raising alarms over ecosystem risks and management lapses.

Antarctic krill stands as the cornerstone of one of Earth’s most vital ecosystems. These small crustaceans feed whales, penguins, seals, and seabirds while also playing a key role in carbon sequestration by transporting nutrients to the ocean depths.
Populations have declined by 70 to 80 percent in parts of the Southern Ocean since the 1970s, a trend linked to climate change, reduced sea ice, and industrial harvesting. The Antarctic Peninsula, home to about one-third of the species’ population, serves as a critical feeding ground now facing intensified pressure.
Background on the MSC Certification
Norway’s Aker QRILL Company, which accounts for roughly 60 percent of the global krill harvest primarily for salmon feed, has held MSC certification since 2010. The Marine Stewardship Council released a draft report in February 2026 recommending a fourth five-year recertification after an assessment by LRQA, a third-party verifier.
The fishery reported 333,873 tonnes of live-weight catch in 2024, representing less than 1 percent of estimated krill biomass. Proponents highlight strict catch limits set by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) as evidence of effective oversight.
Core Concerns from Objectors
The Antarctic and Southern Ocean Coalition (ASOC) submitted its objection on March 2, 2026, followed by the World Wildlife Fund (WWF). Groups argue the assessment overlooks recent setbacks, including a quota overrun in 2025 that forced an unprecedented three-month early closure.
A key CCAMLR spatial management measure lapsed in 2024 amid political deadlock involving Russia and China, leading to concentrated fishing in sensitive areas. Fishing effort in subarea 48.1, vital for penguins and humpback whales, surged 118 percent last season.
- Climate impacts, such as record-low sea ice, undermine reliance on historical biomass data for catch limits.
- Incomplete observer coverage and five-day reporting delays hinder real-time monitoring.
- The “Olympic quota” system encourages a race to fish, displacing wildlife from hotspots.
- Voluntary protections for penguins merely shift pressure rather than reduce it.
- Proposed marine protected areas remain stalled despite scientific backing.
“Our objection is about ensuring that the environmental impacts of the krill fishery have been accurately assessed,” ASOC Executive Director Claire Christian stated.
Responses from Fishery and MSC
Aker QRILL maintains the fishery remains precautionary and supports efforts for stronger CCAMLR measures, including marine protected areas. CEO Matts Johansen described some NGO narratives as counterproductive to consensus-building.
MSC emphasizes its standards require effective management systems and low catch thresholds to protect predators. The organization noted the objections will prompt review by independent adjudicators.
Adjudication and Broader Implications
The objections trigger an independent legal process that could alter the certification or add conditions within months. WWF called for a fishing moratorium until CCAMLR adopts precautionary reforms.
This dispute underscores tensions between aquaculture demand and Antarctic conservation amid rapid environmental shifts.
Key Takeaways
- Krill fishery catch stays below 1 percent of biomass, but local concentrations threaten predators.
- Lapsed CCAMLR measures and climate change amplify risks in the Antarctic Peninsula.
- Independent review could reshape sustainability labeling for this keystone resource.
