CALIFRONIA: With whales present, California wildlife department stops crab fishing to reduce entanglement threat

April 8, 2024 — With humpback whales heading back to their feeding grounds off coastal California and gray whales migrating north to Alaska, the California Department of Fish and Wildlife announced it will close the commercial and recreational Dungeness crab fisheries in southern and central fishing zones including Monterey Bay to reduce the risk of entanglements.

Recently spotters with the department counted as many as 34 humpbacks in one day, said Ryan Bartling, a senior environmental scientists at the wildlife agency. The increased presence of whales observed by planes overhead and vessels on the water triggered the decision to close the fishing season on April 8.

“As it becomes summer, it is not uncommon to see dozens of groups of humpbacks foraging between Monterey Bay and the Gulf of the Farallones (near San Francisco),” he said.

With the closure, the wildlife department is also expected to examine new draft regulations for the fishery, which could set even stricter requirements for when crab fishermen can start fishing with lines and pots and when the season must end.

In former years, before a settlement that led to current regulations limiting the season when the giant mammals are spotted in larger numbers, Dungeness crab fishermen typically started in mid-November and pulled their traps in June. This season, they weren’t allowed to start until late January; fishermen have since pulled in 13 million pounds of crabs worth about $43.4 million.

Whales – and other animals of the sea – can get wrapped up in the lines that connect the pots catching crabs on the ocean floor to buoys on the water’s surface – in 2023, 27 whales were caught in fishing gear off the West Coast, five of which were wrapped up in California Dungeness crab gear, according to National Oceanic and Atmospheric Administration records.

New count of gray whales along West Coast suggests rebound

April 2, 2024 — A new count of the gray whale population along the West Coast shows “signs of recovery” five years after hundreds of them washed ashore and the population began declining, according to the National Oceanic and Atmospheric Association.

Scientists estimate the total number of eastern north Pacific Gray whales to be somewhere between 17,400 and 21,300, an increase from last year’s estimate, which had shown another year of decline. Last season, scientists estimated between 13,200 and 15,960 whales.

“It’s nice to be able to report some good news the last couple of years,” said Aimee Lang, a research biologist with NOAA’s Southwest Fisheries Science Center.

CALIFORNIA: More Whales Are Washing Up Dead on Bay Area Beaches. Why?

November 19, 2021 — Nineteen gray whales have washed up on California’s coast this year, and in many cases there were no clear signs of what killed them. Communities all along the whales’ long migration route are noticing a similar trend, and whale deaths have been above normal for the past three years.

Crabbers team up with scientists

Even as the scientists puzzle out what’s going on, there is some good news.

Back in 2016, there was a spike in West Coast whale entanglements — 48 of the big animals got caught in fishing lines and gear, some of them fatally. Of those, 19 were traced to commercial Dungeness crab gear. So the state worked with fishermen to try to understand what was happening, and what they could all do to prevent the problem.

Dick Ogg is a commercial Dungeness crab fisherman who got involved with the state effort. On a clear morning, with the sun just rising, Ogg maneuvers his boat out of the harbor in Bodega Bay. He’s been fishing these waters for more than two decades, captaining his small boat with two hired workers. He says he often sees whales.

West Coast Gray Whales Declined During Unusual Mortality Event, Similar to Past Fluctuations in Numbers

January 20, 2021 — The following was released by NOAA Fisheries:

The population of gray whales that migrate along the West Coast has declined about 24 percent since 2016. It now stands at an estimated 20,580 whales, a new population assessment (PDF, 7 pages) has found. That is similar to previous fluctuations in the Eastern North Pacific population that has long since recovered from the days of whaling.

The decline coincides with an ongoing Unusual Mortality Event that NOAA Fisheries declared in 2019 for gray whales when strandings increased on the West Coast. It resembles a similar 23 percent decline documented after an unusual mortality event 20 years earlier, in 1999 and 2000. The gray whale population rebounded following that previous UME to greater numbers than before.

The continuing change in gray whale numbers “suggests that large-scale fluctuations of this nature are not rare,” scientists wrote in a NOAA Fisheries Technical Memorandum that reports the new estimate. “The observed declines in abundance appear to represent short-term events that have not resulted in any detectable longer-term impacts on the population.”

Whale strandings may be sign of recovery

April 8, 2020 — A die-off of several hundred gray whales last year might, in fact, represent a promising future for the creatures, according to an expert in marine mammals.

According to NOAA Fisheries, there were 215 gray whale strandings on the Pacific coasts of the United States, Canada and Mexico during 2019, which the administration classified as an unusual mortality event, defined as “a stranding that is unexpected, involves a significant die-off of any marine mammal population and demands immediate response.” A previous gray whale mortality event in 1999 saw an even higher number of strandings.

Bruce Mate has researched marine mammals for more than 50 years and is the former director and endowed chair of the Marine Mammal Institute at Oregon State University.

He said the gray whale population had been reduced to between 1,000 and 2,000 animals by 1900 due to commercial whaling. The 20th century brought protections against over-exploitation of whales, first through the League of Nations and, later, by the International Convention for the Regulation of Whaling. The United States also protected them though the Marine Mammal Protection Act of 1972 and the Endangered Species Act of 1973, all of which helped reduce risks for the population.

Whales are dying, but numbers are unknown. Coronavirus has stalled scientific field work

March 30, 2020 — As gray whales began their northern migration along the Pacific Coast earlier this month — after a year of unusually heavy die-offs — scientists were poised to watch, ready to collect information that could help them learn what was killing them.

The coronavirus outbreak, however, has largely upended that field work — and that of incalculable other ecological studies nationwide.

A large network of marine biologists and volunteers in California normally spend this time of year keeping an eye on gray whales, documenting their numbers and counting strandings as the leviathans swim from Mexico to the Arctic.

Scott Mercer, who started Point Arena’s Mendonoma Whale and Seal Study seven years ago, said the watch was called off last week, as he and his wife were told by a local sheriff to disperse and go home.

NOAA argues to allow Makah Tribe to hunt gray whales off Washington again

November 15, 2019 — More than two decades ago, Makah tribal members killed a 30-foot gray whale in the waters off the Olympic Peninsula amid bitter protests from animal-welfare activists.

The tribal hunt in May 1999 touched off a protracted legal battle that on Thursday took center stage inside a Seattle federal building.

The proceedings over the tribe’s treaty right to hunt gray whales are expected to last more than a week in the courtroomlike setting.

Opponents have raised concerns about the impacts of climate change on the eastern North Pacific gray population, while the tribe hopes Administrative Law Judge George Jordan will recommend a waiver to the Marine Mammal Protection Act.

The Makah, whose lands are on the northwest tip of Washington, have the right to hunt whales through their 1855 treaty with the U.S. government. Tribal whaling advocates hailed the 1999 hunt as an important renewal of a tradition that helps define the Makah. But opponents have so far blocked, through court and regulatory challenges, the tribe from conducting more federally approved hunts.

Will new gray whale migration season prove as deadly as the last one?

October 18, 2019 — Gray whales had a rough go last season as they made their annual migration — skinny, emaciated, even dead whales showing up along the West Coast prompting concern over the health of the species.

With the new season’s first gray whales being spotted in recent weeks off the South Bay, Long Beach and Orange County, whale researchers and enthusiasts are hopeful for a healthier season, one that would indicate the whales found enough food to forage in Alaska as they make their trek to the warm waters of Baja, Mexico.

A young gray whale was spotted last week by Harbor Breeze Cruises, which followed it from the Palos Verdes Peninsula to Long Beach. Another was seen off the PV Peninsula earlier in the month, and another around Torrance Beach.

Orange County’s first gray whale sighting was reported Tuesday, Oct. 15, first by a diver near the Newport Pier and then by a Dana Wharf boat captain.

Something killed 121 gray whales this summer. Scientists are scrambling to find out what

September 19, 2019 — Something killed 121 gray whales this spring and summer, and scientists are struggling to find out what it was.

The dead giants of the ocean washed up on West Coast beaches as they finished their annual epic migration to their winter feeding grounds between Alaska and Russia. Many were emaciated and appeared to be starving.

The near-final death count, tallied this week, makes this the second-worst year on record for gray whales, which were hunted almost to extinction in the late 1800s. It could represent as much as 10% of the species’ total population.

“I wouldn’t be surprised if our team comes across other carcasses,” said Megan Ferguson, a fisheries biologist with the Cetacean Assessment and Ecology Program of the National Marine Fisheries Service.

7 Gray Whales Found Dead In Alaska Over Holiday Weekend, Pushing Toll To 22

July 15, 2019 — Seven gray whales were found dead on Alaska’s shores over the holiday weekend, sending this year’s toll in the state to 22.

According to the National Oceanic and Atmospheric Administration, a necropsy to help determine the cause of death was performed on one of the four animals that turned up around Kodiak Island. Two others were discovered in Egegik and another at Takli Island. The whales were all found between July 5 and 7.

NOAA Fisheries Alaska region spokesperson Julie Speegle told HuffPost on Friday that while the investigation of the deaths remains in its early stages, starvation triggered by melting sea ice may be a cause.

“As many of these whales have been skinny, scientists theorize there may have been a disruption in the gray whale food source due to a lack of sea ice in the Arctic last summer,” Speegle said. “Gray whales fatten up during the summer by feeding on marine life in the Arctic, mostly amphipods off the ocean floor. But when sea ice melts and retreats (as it did last summer), there is a disruption in the food web that results in fewer amphipods for gray whales to eat.”

Though Speegle did not say whether climate change could be to blame for the deaths, she noted that Arctic sea ice dropped to its sixth lowest extent on record last summer, “which may have caused a disruption in the food supply for gray whales.”
