A record catch of krill near Antarctica could trigger an unprecedented end to fishing season
MIAMI (AP) — Trawling near Antarctica for krill — a crustacean central to the diet of whales and a critical buffer to global warming — has surged to a record and is fast approaching a never before reached seasonal catch limit that would trigger the unprecedented early closure of the remote fishery, The Associated Press has learned.
The fishing boom follows the failure last year of the U.S., Russia, China and two dozen other governments to approve a new management plan that would have mandated spreading out the area in which krill can be caught and creating a California-sized reserve along the environmentally sensitive Antarctic Peninsula.
In the first seven months of the 2024-25 season, krill fishing in Antarctica reached 518,568 tons, about 84% of the 620,000-ton limit that, once reached, will force the fishery to automatically close. In one hot spot, the catch through June 30 was nearly 60% higher than all of last year's haul, according to a report from the Commission for the Conservation of Antarctic Marine Living Resources, or CCAMLR, the international organization that manages the world's southernmost fishery.
The report, which has not been publicly released and CCAMLR said contains confidential data, was shared with The AP by someone concerned about overfishing in Antarctica on the condition of anonymity because they were not authorized to release the information.
'The vast majority of the krill take is from an increasingly smaller area,' said Capt. Peter Hammarstedt, campaign director for conservation group Sea Shepherd Global, which this year made its third voyage to Antarctica to document the fishery. 'It's the equivalent of a hunter saying that they're only killing 1% of the U.S.' deer population but leaving out that all of the deer were shot in Rhode Island.'
Threat from climate change, advances in fishing
Krill is one of the most abundant marine species in the world, with an estimated biomass of 63 million metric tons. But advances in fishing, climate change and growing demand for krill's Omega-3 rich oil – for fishmeal, pet food and human dietary supplements — have increased pressure on the krill stocks. In the 2023-24 season, a fleet of 12 industrial trawlers from mostly Norway and China caught 498,350 tons of krill — until now the largest harvest since CCAMLR began collecting catch data in 1973.
AP journalists traveled to the icy waters around Antarctica in 2023 and observed how factory ships trawl in close proximity to whales whose numbers are still recovering from a century of industrial culling that nearly drove them to extinction.
Underscoring the competition between humans and whales, three humpback whales were found dead or seriously injured last year in the long, cylindrical nets deployed by the vessels to vacuum up the paper-clip sized crustacean.
Officials have been negotiating for years a new management plan that would balance the growing market for krill with calls for greater protection of the Antarctic Peninsula, the continent's northernmost point and an area teeming with whales and, increasingly, tourists. Currently, less than 5% of the Southern Ocean is protected — well behind CCAMLR's target and a United Nations goal to preserve 30% of the world's oceans by 2030.
But a tentative deal fell apart at last year's CCAMLR meeting over a last minute proposal by the United Kingdom and Australia for an even lower catch limit than the one agreed to during talks, AP reported last year. China, objecting to the persistent Western demands, then withdrew its support for the marine reserve and refused to renew the existing management system.
'The truth was it was the UK,' Matts Johansen, chief executive of Norway's Aker BioMarine, the world's largest supplier of krill-based products, said at the United Nations Oceans conference in June. 'Just a couple days before the vote, the UK threw another suggestion and that's when the Chinese backed off.'
A spokesperson for the UK Foreign Office rejected that characterization and said the British government continues to push for a krill management strategy that better safeguards Antarctic marine species and vulnerable ecosystems.
Catch limit restrictions expire
In the absence of a deal, restrictions adopted 15 years ago to spread out the catch limit expired, allowing the krill fleet to essentially fish anywhere at any time, including in smaller habitats preferred by whales and other animals such as penguins and seals.
Krill aren't just vital to marine ecosystems. Increasingly, researchers are focusing on their role as a bulwark against climate change. One peer-reviewed study last year found that krill remove from the atmosphere and store in the ocean 20 million tons of carbon annually. That's the equivalent of taking off the road 5 million cars every year.
CCAMLR declined to comment on the report obtained by the AP.
Ship tracking data analyzed by Global Fishing Watch at the request of the AP also showed a higher concentration of trawling. Activity in one popular fishing ground, denoted Sub-Area 48.1, appears to have more than doubled so far this season compared to the entire 2023-2024 season, according to the the U.S.-based group, which supports sustainable fishing.
Javier Arata, the executive director the Association of Responsible Krill harvesting companies, whose members are responsible for 95% of the krill taken from Antarctica, said the catch limit that lapsed was always intended as an interim measure.
His group supports the creation of marine protected areas in Antarctica. But it rejects waiting for a conservation deal to adopt 'ready-to-go measures' raising the quota, which he said can be much higher.
'The failure to advance management was political, not scientific,' he said.
The current fishing levels, although higher than previous limits, remain sustainable and reflect the consensus recommendation of scientists before last year's deal fell apart, Arata added.

New RADIOHEAD Study Validates Use of Guardant Reveal Tissue-Free Monitoring for Earlier Detection of Immunotherapy Response in Advanced Cancer
The first readout from Guardant's research collaboration with the Parker Institute for Cancer Immunotherapy (PICI) shows Guardant Reveal detected responses to immunotherapy across multiple tumor types and identified non-responders up to 5 months earlier than standard methods Study shows Guardant Reveal's promise for confirming effective therapies earlier and optimizing treatment faster in patients with advanced cancer PALO ALTO, Calif., July 29, 2025--(BUSINESS WIRE)--Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced the first clinical readout from their collaboration in the RADIOHEAD study with the Parker Institute for Cancer Immunotherapy (PICI), a network of the largest concentration of immuno-oncology (IO) expertise in the world. The data, published today in Cancer Research Communications, a journal of the American Association for Cancer Research, found that Guardant Reveal successfully detected responses to immunotherapy across multiple solid tumor types in advanced stage cancer patients and identified non-responders more than three months—and in some cases nearly five months—before disease progression was visible by standard methods. Approximately 30% of patients with advanced-stage cancer receive immunotherapy treatment, with varying degree and duration of response. This study analyzed a large cohort of more than 500 patients with various advanced solid tumors, including lung, skin, head and neck, breast, GI, GU, and gynecologic cancers, receiving immunotherapy in a real-world setting to assess if blood-based monitoring could predict response accurately and faster than standard of care methods. The strong association found between long-term patient outcomes and changes in tumor fraction as measured with the tissue-free, methylation-based Guardant Reveal supports the use of blood-based monitoring to help predict treatment response and improve decision-making in cancer care. "Precise serial monitoring at the molecular level provides real value to oncologists and to patients using immunotherapy," said Craig Eagle, M.D., Chief Medical Officer at Guardant Health. "This study shows that Guardant Reveal has the potential to revolutionize how oncologists assess patient response, identifying earlier insights that can empower them to make informed decisions faster and improve patient outcome and quality of care." "Our RADIOHEAD study of Guardant Reveal in advanced stage cancers provides patients with a new caliber of precision monitoring in order to create better patient outcomes," said Tarak Mody, PhD, Chief Business Officer at PICI. "These findings exemplify PICI's commitment to forging mission-driven partnerships to bring cutting-edge technology into clinical practice, accelerate discoveries, and advance the development of curative immune therapies for patients." Key study findings include: Improved patient outcomes associated with any reduction in tumor fraction 75% lower risk of progression in patients with ≥80% decrease in tumor fraction Disease progression identified up to 5 months prior to standard of care methods The full manuscript in Cancer Research Communications is available here.

California's Wildfire Emissions Top Its Power Plants, But Go Uncounted
When wildfires ravaged Los Angeles County earlier this year, they destroyed thousands of homes and caused exorbitant insurance claims. But a less obvious disaster also occurred: satellites detected massive plumes of CO₂, rivaling the yearly emissions of some small countries. In just days, the fires released more carbon pollution than all of California's passenger vehicles emit in a month. Yet none of it counts toward the state's official climate ledger. Despite California's ambitious climate laws and sophisticated carbon accounting, emissions from wildfires are treated as natural disasters—uncontrollable and, therefore, unaccountable. But with wildfires now exacerbated by fossil fuel combustion, hotter weather, and poor forest management, experts say this blind spot is no longer defensible. Fires are both a consequence and a contributing factor to the climate crisis. 'Wildfires in California have become a major and growing source of greenhouse gas emissions,' said Michael Jerrett, professor at UCLA's Fielding School of Public Health, in a study. 'Wildfire emissions in 2020 essentially negate 18 years of reductions in greenhouse gas emissions.' In that year, wildfires released an estimated 127 million metric tons of CO₂—twice the amount produced by California's entire power sector. Because these emissions originate from trees rather than smokestacks, they are often excluded from climate inventories due to a technicality known as the 'fast carbon cycle.' The idea is that forests will eventually reabsorb the carbon they release. However, with longer fire seasons and declining ecosystems, that reabsorption is no longer assured. Today's wildfires burn hotter, spread faster, and start more easily than those of decades past. Rising global temperatures, prolonged drought, earlier snowmelt, and increasingly dry vegetation are all part of the equation. So is human encroachment into fire-prone areas, which increases ignition sources—from cars to power lines—and puts more lives and infrastructure at risk. "In a warmer world, we're already seeing more extreme wildfires that put both people and nature at risk," said Katharine Hayhoe, chief scientist for The Nature Conservancy's publication. 'More than a century of fuel build-up, past land and fire management, fire exclusion, and expansion into the wildland-urban interface all play a part.' Carbon Risk Is Becoming A Financial Liability The Global Wildfire Information System estimates that wildfires release between 5 and 8 billion tons of CO₂ each year—roughly one-fifth of the total emissions from the entire cement industry, one of the world's biggest polluters. These fire-related emissions are often viewed as byproducts of global warming. But that's changing. The consequences of ignoring wildfire emissions are no longer just ecological—they're economic. Wildfires disrupt everything from supply chains and insurance premiums to asset valuations. Companies with fire exposure may experience a decline in their valuations, particularly as investors scrutinize climate-related risks. A McKinsey study found that 83% of Fortune Global 500 companies have climate-related targets; however, far fewer address nature-based threats, such as wildfires, drought, or land degradation. This leaves firms vulnerable not only to physical damage but also to shareholder lawsuits and director liability. Some institutions are responding. The USDA Forest Service and EPA have begun integrating wildfire emissions into national inventories. Platforms like Climate TRACE, which use satellites to monitor pollution in real-time, reveal that we underreport carbon sources, including wildfires. Meanwhile, reinsurers and insurers—who shoulder billions in wildfire losses—are calling for climate-adjusted pricing. And S&P Global Ratings and Moody's warn that utilities with wildfire exposure face mounting credit risks unless they invest in prevention, resilience, and emergency planning. The real-world results and the remedies? Few examples illustrate the financial fallout of fire-driven climate risk better than PG&E. The utility filed for Chapter 11 bankruptcy in January 2019, overwhelmed by $30 billion in liabilities linked to fires between 2015 and 2018. Investigators determined that PG&E's equipment caused several major blazes, including the 2018 Camp Fire, the deadliest and most destructive in California history. The company emerged from bankruptcy in 2020 after agreeing to a $13.5 billion settlement with fire victims and pledging billions toward safety upgrades. The utility has become a case study in the cost of ignoring climate exposure. PG&E now routinely shuts down power during high-risk conditions. While controversial, Hawaiian Electric and PacifiCorp employ similar tactics. Climate Leadership Requires Carbon Accountability The bankruptcy also changed how the entire utility sector views risk. Companies now invest in vegetation management, grid modernization, and predictive analytics. But even these steps only address the triggers and technical solutions—not the obvious disconnect centered on carbon math. California continues to lead the nation in climate policy, with ambitious targets for zero-emission energy and net-zero emissions by 2045. Governor Gavin Newsom has invested in forest thinning, prescribed burns, and firefighting capacity. But wildfire emissions are still excluded from the state's formal climate goals. 'The debate is over around climate. Just come to the state of California. Observe it with your own eyes,' Newsom said in 2020, surveying wildfire damage. That line captured both the urgency and irony. While California acts boldly on decarbonization, it still underestimates one of its largest and fastest-growing sources of CO₂. The result is a policy blind spot with global implications. When California's fires take out the forests and emit more CO₂ in a single season than the state's power sector, we are not addressing the climate crisis—we are just greenwashing it.
