UC Santa Cruz study finds new method to predict domoic acid outbreaks

October 14, 2026 — Domoic acid was likely the culprit behind an unusually high number of sea lion strandings on the Monterey Bay coast over the summer. The neurotoxin can affect marine mammals, birds and even humans, but outbreaks are difficult to predict. Now, researchers from UC Santa Cruz have pioneered a new detection method that could give weeks of notice before domoic acid becomes dangerous to humans. The research team’s study on the method was published Sept. 30 in the Proceedings of the National Academy of Sciences.

“This method gives us a much bigger window of time,” said Raphael Kudela, a distinguished professor at UCSC and senior author of the study. “We could tell you six weeks in advance, potentially … A much more early warning than you get using our other methods.”

Domoic acid is a toxin produced by Pseudo-nitzschia, a species of algae. The toxin accumulates in the food chain. Small fish such as anchovies eat the algae, and domoic acid along with it. Then the predators of those fish, including sea lions, seals and birds, become sick. The toxin also makes its way into filter feeders and can cause illness in humans who eat affected shellfish.

The catch with bycatch: Saving sharks goes beyond no-fishing policies

October 8, 2026 — The go-to solution for protecting most marine wildlife is to create designated areas where fishing is strictly prohibited. But when it comes to wide-ranging marine animals — such as fast-moving sharks in the tropical waters of the Galápagos Islands off the coast of Ecuador — there’s a catch.

Bycatch, that is.

The long fishing lines of tuna boats can accidentally drift into the marine reserves, and they often catch a lot more than tuna — mainly, sharks, turtles and sea lions. This unintentional capture is called bycatch.

“People think that by setting a reserve, that’s getting to an outcome, but it’s not,” said Leah Gerber, professor in Arizona State University’s School of Life Sciences and founding director of the Center for Biodiversity Outcomes. “We really wanted to highlight that. What are the implications of this and what really would work?”

Gerber led a new study she co-authored that reveals how data, local knowledge and community collaboration can help shape more effective solutions.

The study compared the efficacy of no-fishing conservation areas with bycatch reduction in the Galápagos Marine Reserve. The researchers ultimately found that reducing bycatch was likely to have a higher conservation impact on sharks.

ALASKA: Trump administration order urges ‘robust’ harvest of sharks, seals and sea lions

September 28, 2026 — The White House this month issued an executive order to support the sportfishing industry by, among other things, paving the way for increased harvests of sharks and pinnipeds, including sea lions and seals.

The order specifically aims to help saltwater anglers, offshore boaters and charter operators — an industry in Alaska that, with its copious fish populations, generates thousands of jobs and more than $1 billion in economic impact, according to the state Department of Fish and Game.

If all of its provisions are enacted, fishing groups say, the directive could improve fish abundance in Alaska by reducing predation by marine mammals. It could also lead to potential conflicts with federal laws that currently protect the animals.

US House committee advances bill expanding culling of salmon-eating seals and sea lions

September 16, 2026 — The U.S. House Natural Resources Committee has approved a bill that would allow the state of Washington and area Tribes to kill more seals and sea lions that prey upon recovering salmon populations.

“I am pleased the House Natural Resources Committee voted in a bipartisan manner to advance my bill,” U.S. Representative Michael Baumgartner (R-Washington) said in a release. “This bill, born in collaboration with many of the Tribes in Washington who have federally recognized treaty fishing rights, is an important step in the right direction to protect salmon populations in the Pacific Northwest. I look forward to continued bipartisanship as we work to get it signed into law before the end of this Congress.”

US research buoys are caught in currents of change

September 8, 2026 — A research buoy is something like an ant: A single one might not look like much, but put a bunch together and they can make something truly impressive.

In the water, a buoy becomes part of a larger system. Together, they provide all kinds of functions, from conducting ocean and weather research to helping satellites stay calibrated.

Buoys can handle almost anything the sea throws at them. William Burnett, a meteorologist who has led the National Data Buoy Center since 2022, described them continuing to collect data even after being “hit dead center by hurricanes.” That’s on top of the usual sources of wear-and-tear: rain, ice, barnacles, saltwater.

One of the biggest threats to buoys comes from surprisingly cute sources: seals and sea lions.

“We were noticing that the buoy cables were being chewed through,” Burnett noted in a phone interview.

To get around the problem, the National Data Buoy Center installed cages around the research devices. That’s mostly worked, though smarter animals do find a way to mess with them, even using them like makeshift surfboards.

“If they can find the platform,” Burnett said of these rambunctious animals, “they’ll get on it.”

Can killing seals save salmon? Conservationists and Washington lawmakers disagree

July 23, 2026 — A marine wildlife hospital based in the Pacific Northwest is worried about an alarming trend: seals coming to them alive, but gravely injured.

Earlier this month, the organization treated its third seal in less than a year with a gunshot wound. That seal pup, named Waffles, was found over Fourth of July weekend. It had to be euthanized once it was determined its injuries were too severe.

“It’s not uncommon for us to see animals that have been shot,” said Casey Mclean, executive director and veterinary nurse at SR3 SeaLife Response + Rehab + Research. “Historically, we often found those animals dead. Now we’re starting to see more of them alive and suffering from gunshot injuries.”This trend, Mclean believes, is being fueled by misinformation about the role marine mammals play in Washington’s continually struggling salmon populations.

Her concern is amplified by a congressional bipartisan bill from two Washington lawmakers, U.S. Rep. Michael Baumgartner, a Republican, and U.S. Rep. Emily Randall, a Democrat. The Northwest Endangered Salmon Predation Prevention Act (H.R. 9621) would expand the ability of federal, state, and tribal authorities to remove seals and sea lions, known collectively as pinnipeds, from Washington waters in an effort to boost salmon recovery.

In statements to KING 5, both sponsors of the bill lambasted the shooting of the seal pup as illegal, but insisted it should not be confused with what they’re proposing.

“Joe Schmo or any person off the streets shouldn’t be shooting seals or sea lions,” Randall said. “What we have proposed is a robust process to figure out how we can have responsible management of a population that’s decimating our salmon.”

“No one should be illegally poaching sea lions,” Baumgartner said. “I hope the perpetrator is identified and brought to justice. This does not have anything to do with my bipartisan bill to try to save and restore our endangered salmon populations.”

Supporters of the proposal, like the representatives, argue reducing pinnipeds could help struggling salmon populations. However, critics like Mclean say the bill ignores more significant threats to salmon and risks repeating decades-old mistakes in wildlife management.

50 Years of Environmental Data Can Predict Health and Strandings of Sea Lions Pups in California

March 30, 2025 — For more than 50 years, NOAA Fisheries has conducted vital research on seal and sea lion populations at a remote research station on San Miguel Island, California. The long-term data set provides clues to help us understand what environmental conditions lead to malnourished California sea lion pups and increased stranding levels. This information is important for managing their populations and helping rehabilitation centers prepare for periods when sea lion pup strandings may be elevated.

Our research began on San Miguel Island in 1969 after scientists discovered a colony of northern fur seals breeding on Point Bennett the year before. This amazing uninhabited island lies 26 miles offshore of the California coast. It’s part of the Channel Islands National Park and is home to some of the largest populations of land-breeding pinnipeds in the world. Prior to this discovery, northern fur seals were last documented in California during the early 1800s—before their population was wiped out by seal hunters. Researchers began studying the new colony of fur seals along with California sea lions that also breed on the island.

Sea lions keep gorging on endangered salmon despite 2018 law

December 4, 2025 — Efforts to stop Pacific sea lions from feasting on endangered salmon and steelhead have largely failed despite millions of taxpayer dollars spent on those efforts, lawmakers were told Wednesday.

In a hearing on the efficacy of the Endangered Salmon Predation Prevention Act adopted in 2018, witnesses told members of the House Natural Resources Subcommittee on Water, Wildlife and Fisheries that wildlife managers have been unable to check a sustained population boom of the salmon-devouring pinnipeds — marine mammals with both front and rear flippers — that began in the 1990s.

“These animals are remarkably resilient, and they do know where their food source is,” Sam Rauch, deputy assistant administrator for NOAA Fisheries, told the subcommittee. “It is very difficult to encourage them to leave with anything less than force,” which usually means trap and kill.

US Congress holds hearing on sea lion removals and salmon predation

December 4, 2025 — The U.S. House Water, Wildlife, and Fisheries Subcommittee held a hearing on sea lion predation on salmon and the effectiveness of killing the mammals to slow down the trend.

Under the Marine Mammal Protection Act (MMPA), sea lions skyrocketed from a population of roughly 10,000 in the 1950s to 250,000 today. That spike has been seen as a success story for the MMPA, but it’s also had a major impact on salmon populations, which are a key food source for pinnipeds. By traveling upriver to avoid their natural predators – orcas – sea lions are able to feast on already struggling salmon populations. Since 2002, California and Steller sea lions have eaten roughly 98,000 salmon at just two sites: Bonneville Dam and Willamette Falls, Oregon.

Natural Resources plans hearings on energy, parks, fisheries

December 2, 2024 — The House Natural Resources Committee is planning a trio of hearings this week as it ramps up its activity following the extended recess during the government shutdown.

The Oversight and Investigations Subcommittee, headed by Rep. Paul Gosar (R-Ariz.), will hold a hearing titled “Unleashing American Energy Dominance and Exploring New Frontiers.” It’s the latest in a string of hearings focused on the new administration’s pro-development energy posture.

The Water, Wildlife and Fisheries Subcommittee, led by Rep. Harriet Hageman (R-Wyo.), will question witnesses on sea lions eating salmon in the Pacific Northwest. Congress approved legislation in 2018 making it easier for states and tribes to kill sea lion that congregate near dams and other areas to eat the salmon.
