A prolonged marine heatwave off the California coast is altering whale migration and feeding behavior, increasing the risk of entanglements with commercial fishing equipment and accelerating efforts to expand whale-safe fishing technologies across the U.S. west coast.

Scientists say warming offshore waters are shrinking the cold, nutrient-rich zones that sustain krill, anchovies and sardines, key prey species for humpback whales. As those prey populations move closer to shore, whales are increasingly entering areas heavily used by California’s Dungeness crab fleet.

The overlap has intensified concerns over the fishery’s conventional trap system, which relies on vertical lines extending from traps on the seafloor to floating surface buoys. Tens of thousands of such lines can remain in the water during crab season, creating entanglement hazards for whales migrating and feeding along the Pacific coast.

California regulators this spring again imposed restrictions on portions of the commercial crab fishery off central California, temporarily closing areas to traditional gear as whale activity increased near fishing grounds.

Similar closures have become more common in recent years as ocean warming disrupts long-established migration and feeding patterns.Marine biologists say humpback whales face the greatest risk because of their behavior around fishing equipment.“Humpbacks are curious and they’ll scratch their backs on the gear,” said Kathi George, director of cetacean conservation biology at The Marine Mammal Center.

“If they get a line caught on their body, they’ll breach and they’ll roll and end up entangling themselves.”Entangled whales can remain trapped in fishing gear for months, often dragging heavy equipment across long distances.

Researchers say the strain can prevent whales from feeding or diving normally, contributing to exhaustion, infection, starvation and drowning.According to the National Oceanic and Atmospheric Administration, 36 whales were confirmed entangled along the U.S. west coast in 2024, the highest reported number since 2018.

Scientists caution that many incidents likely go unrecorded because entangled whales can disappear offshore before being observed.In response, California approved commercial deployment of ropeless “pop-up” crab fishing systems for the first time this year, allowing parts of the fleet to continue operating later into the season while reducing risks to marine mammals.

The technology eliminates permanently floating buoy lines. Instead, ropes and buoys remain stored with the trap on the seafloor until fishermen return and activate an acoustic release mechanism that sends the gear to the surface.

Supporters say the system could substantially reduce whale entanglements while allowing fishermen to maintain harvests during periods when traditional gear would otherwise be prohibited.

Environmental groups and fisheries managers increasingly view adaptive fishing systems as necessary as climate-driven ocean changes intensify along the Pacific coast.

Scientists expect continued overlap between whales, shipping traffic and fishing operations as warming conditions reshape marine ecosystems.“We will have to continue to be adaptive and science driven in terms of our management to reduce wildlife risk and keep fishermen on the water,” said Caitlynn Birch, a marine scientist and Pacific campaign manager at Oceana.

Birch said California’s transition toward whale-safe fishing systems could become a model for other fisheries operating along the west coast.Separate monitoring efforts are also expanding in California’s coastal waters as researchers and conservation agencies seek to better track whale movements in high-risk areas.

Camera systems installed near locations including Golden Gate Bridge and Alcatraz Island may eventually support broader surveillance coverage across the San Francisco Bay region to improve detection of whales moving near shipping lanes and fishing zones.

Marine heatwaves in the Pacific have become more frequent and intense over the past decade, affecting fish populations, marine mammal migration routes and coastal fisheries.

Researchers say those changes are forcing regulators and fishing industries to adopt increasingly flexible management systems capable of responding quickly to changing environmental conditions.

Wale, elected by lawmakers on Friday after the removal of former prime minister Jeremiah Manele, named former premier Rick Hou as foreign minister and legislator Peter Kenilorea as minister for National Planning and Development Coordination, portfolios central to the country’s foreign aid and diplomatic engagement.

The appointments are being closely watched by regional governments and Western allies as the strategically located Pacific archipelago remains an arena of competition between China and Australia for political and security influence.

Kenilorea is a member of the Inter-Parliamentary Alliance on China, a multinational group critical of Beijing’s policies. James Batley, a former Australian high commissioner to the Solomon Islands, said the appointments suggested a greater emphasis on transparency, although he said it was unlikely Honiara would reverse its 2019 decision to switch diplomatic recognition from Taiwan to China.

Hou, who served as prime minister from 2017 to 2019 before the diplomatic switch, had publicly opposed the move to sever ties with Taiwan. Batley described Hou as experienced in international affairs and unlikely to be easily pressured in diplomatic negotiations.

Chinese Ambassador Cai Weiming and Australian High Commissioner Jeff Roach both met Wale over the weekend as regional powers moved quickly to engage the new administration.

According to a statement from the prime minister’s office, Wale told Cai that the Solomon Islands remained committed to the One China policy and intended to continue cooperation with Beijing to deliver economic benefits.

In separate talks with Australia, Wale said Canberra should adopt a longer-term approach to deepening bilateral ties, while describing Australia as the country’s longstanding development partner.

The government also restored a prohibition on the export of live dolphins, reversing a decision by the previous administration to lift the ban days before its collapse.

Environmental campaigner Lawrence Makili welcomed the move, saying it would help protect both marine life and the international reputation of the Solomon Islands’ tuna industry, one of the country’s largest sources of export revenue.

The issue gained prominence after a company applied to capture and export 50 dolphins, prompting criticism from conservation groups concerned about the impact on marine ecosystems and trade perceptions abroad.

While dolphin hunting in Malaita has historically been tied to traditional practices involving dolphin teeth, the commercial export of dolphins to aquariums in China has drawn increasing scrutiny in recent years.

This innovative approach addresses one of the key challenges in environmental monitoring: the shortage of high-quality training data for artificial intelligence applications in ecological protection and disaster management.

By generating synthetic data from limited real-world samples, KAUST researchers enable predictive AI models to detect potential oil spills more accurately and efficiently, enhancing rapid response capabilities.

Early detection of oil spills is critical to minimizing environmental damage, protecting marine ecosystems, and ensuring the health of coastal communities while supporting sustainable industrial practices.
