CALIFORNIA: Humboldt Bay crab fishing season ‘devastated’ by COVID-19

March 26, 2020 — Crab fishing in Humboldt County has seen better days, but it’s never been as bad as this, several fishermen said Tuesday.

“We could use one word: it’s devastating,” said Harrison Ibach, president of the Humboldt Fishermen’s Marketing Association. “Everything has come to a screaming halt. And it’s not just the crab industry, it’s the entire seafood industry.”

Ibach and others estimated that the best market price for a pound of crab in Humboldt County — from the few buyers left — stands around $2 per pound, down from $3 at the start of this year’s season. For Ibach, “that’s the lowest I’ve seen in many, many years.”

The crabbing season naturally slows down in March, but the global coronavirus pandemic has brought unprecedented new levels of decline to the industry, fishermen said. It started when China — a top shipping location for live crabs — stopped taking in product from Humboldt Bay fishermen after the virus began wreaking havoc in the country.

In the couple of months that followed, the domestic market has similarly plummeted. Now that the ongoing statewide shelter-in-place order has closed most restaurants, almost no one in Humboldt County is buying crab.

West Coast Dungeness Crab Stable or Increasing Even With Intensive Harvest, Research Shows

March 5, 2020 — The following was released by NOAA Fisheries:

The West Coast Dungeness crab fishery doesn’t just support the most valuable annual harvest of seafood on the West Coast. It’s a fishery that just keeps on giving.

Fishermen from California to Washington caught almost all the available legal-size male Dungeness crab each year in the last few decades. However, the crab population has either remained stable or continued to increase, according to the first thorough population estimate of the West Coast Dungeness stocks.

“The catches and abundance in Central California especially are increasing, which is pretty remarkable to see year after year,” said Kate Richerson, a research scientist at NOAA Fisheries’ Northwest Fisheries Science Center in Seattle. Richerson is the lead author of the new study published in the journal Fisheries Research. “There’s reason to be optimistic that this fishery will continue to be one of the most productive and on the West Coast.”

Other recent research has suggested that the West Coast’s signature shellfish could suffer in the future from ocean acidification and other effects related to climate change. That remains a concern, Richerson said, but the study did not detect obvious signs of population-level impacts yet.

After 2017 Lawsuit, Fewer Whales Entangled As Crab Fishers Face Financial Struggle

February 14, 2020 — The Dungeness crab fishery in California recently shut down months early after a 2017 lawsuit filed by the Center for Biological Diversity (CBD) that required crab fishers to pull their gear out of the water with only 3 weeks notice. A settlement agreement was reached in March 2019, which included an early closure for the 2018-2019 Dungeness crab fishing season. Fishing gear is a serious threat to whales that live in, and migrate through, California waters. The California Dungeness Crab Fishing Gear Working Group, convened by the California Department of Fish and Wildlife (CDFW), informs regulators on ways in which to minimize entanglement risks and protect whales.

Why have there more whale entanglements recently?

According to a new paper published in the journal Nature Communications climate change could be responsible. According to lead researcher Jarrod Santora, warming events in recent years, combined with recovering whale populations cause whales to come in contact with crab fishing gear more regularly.

Crab season in California occurs between November and mid-July. Warming events in 2014-2016 caused an increase in the marine algae Pseudo-nitzschia which produce the neurotoxin domoic acid (the toxin causes shellfish poisoning in humans). In 2016, high levels of toxins delayed the crab season until March. In addition, the warmer waters changed feeding habits of humpback whales, steering them closer to shore where food was more prevalent. This perfect storm of events led to a sharp spike in observed whale entanglements in 2017. 70% of the whale entanglements reported in 2017 in the United States involved fishing gear.

The Pacific Ocean is so acidic that it’s dissolving Dungeness crabs’ shells

January 28, 2020 — The Pacific Ocean is becoming more acidic, and the cash-crabs that live in its coastal waters are some of its first inhabitants to feel its effects.

The Dungeness crab is vital to commercial fisheries in the Pacific Northwest, but lower pH levels in its habitat are dissolving parts of its shell and damaging its sensory organs, a new study found.

Their injuries could impact coastal economies and forebode the obstacles in a changing sea. And while the results aren’t unexpected, the study’s authors said the damage to the crabs is premature: The acidity wasn’t predicted to damage the crabs this quickly.

“If the crabs are affected already, we really need to make sure we pay much more attention to various components of the food chain before it is too late,” said study lead author Nina Bednarsek, a senior scientist with the Southern California Coastal Water Research Project.

The findings were published this month in the journal Science of the Total Environment and funded by the National Oceanic and Atmospheric Administration (NOAA). The agency studies ocean acidification and how changing pH levels are impacting coasts.

Crab larvae off Oregon and Washington suffering shell damage from ocean acidification, new research shows

January 27, 2020 — Ocean acidification is damaging the shells of young Dungeness crab in the Northwest, an impact that scientists did not expect until much later this century, according to new research.

A study released this week in the journal Science of the Total Environment is based on a 2016 survey of Oregon, Washington and British Columbia coastal waters that examined larval Dungeness. The findings add to the concerns about the future of the Dungeness as atmospheric carbon dioxide — on the rise due to fossil-fuel combustion — is absorbed by the Pacific Ocean and increases acidification.

“If the crabs are affected already, we really need to make sure we start to pay attention to various components of the food chain before it is too late,” said Nina Bednarsek, the lead author among 13 contributing scientists. The study was funded by the National Oceanic and Atmospheric Association (NOAA).

Ocean Acidification Threatens the U.S. Economy

January 3, 2020 — Ocean acidification threatens to cause billions of dollars in damage to the U.S. economy, harming everything from crabs in Alaska to coral reefs in Florida and the Caribbean, NOAA researchers said in a new report.

Carbon dioxide emissions and ocean acidification are occurring at an “unprecedented” rate, deteriorating valuable fisheries and tourist destinations across the United States and its territories, NOAA said in a draft research plan for ocean acidification.

“Commercial, subsistence and recreational fishing [and] tourism and coral ecosystems” will likely be damaged by ocean acidification, the plan said. Multibillion-dollar fisheries such as West Coast Dungeness crab, Alaska king crab and New England sea scallops are vulnerable. So are Florida’s coral reefs, an asset valued at $8.5 billion.

Implicating human activities such as burning fossil fuels, the plan said that ocean acidification “is driven by the growing amount of anthropogenic carbon dioxide absorbed and dissolved in the upper ocean.” Ocean acidification makes it hard for some marine organisms such as lobsters, oysters and coral to build shells and skeletons.

Central California Dungeness opens, but Northwest awaits 2020

December 13, 2019 — With the danger of whale entanglements eased, the Dungeness crab season for central California will open Sunday. But lackluster meat quality led Northwest state fisheries manager to delay opening other coastal areas until the New Year.

Officials from California, Oregon and Washington state wildlife agencies conferred Dec. 6 and agreed on the delay, citing meat recovery values still below 25 percent in areas on the northern coast. The continuing closure will remain in effect from Point Arena, Calif., north to the Canadian border, “through December 3, 2019 at least,” according to a joint statement issued through the Washington Department of Fish and Wildlife.

Testing protocols specify season delays for any area where sampled crabs do not meet the minimum standards for meat recovery, with additional testing before a new opening date can be set. The state agencies are sampling again in mid-December with an eye to having complete results Dec. 20.

It’s a rocky start to the beginning of the winter fishery that has had more than its share of problems, from domoic acid to marine mammal conflicts. The California opener originally set for Nov. 22 was delayed, after the Bodega Bay crabbing fleet voted to voluntarily hold back from deploying their gear until a large number of endangered humpback whales had finished feeding in their nearshore zone.

West Coast Crab Managers Delay Primary Dungeness Season Again

December 10, 2019 — SEAFOOD NEWS — State fishery managers confirmed Friday the primary Dungeness crab season will be delayed until after Christmas in Washington, Oregon and California due to spotty meat quality. The delay will last until at least Dec. 31.

Some areas showed improvement in the last month to meet season-opening criteria of either 23 or 25 percent, depending on the area. However, too many areas in between the improved areas were still below the thresholds and managers decided to delay the season from the U.S./Canadian border to Point Arena, Calif., again to let the crab fill out more.

The third round of meat recovery testing will be conducted sometime in mid–December, targeting completion by Dec. 20. The results will determine if the season should open Dec. 31, be further delayed or be split into separate areas with different opening dates.

Industry members in all three states generally agreed with the decision, choosing to wait in the hopes the whole coast can open at once. The delay will also ensure consumers get the best and fullest crab available with the season does open.

But not everyone was happy with the decision. Some fishermen were counting on a big payday in December to cover bills. Other fishermen simply wanted to access full, healthy crab after seasons in which some ports had to wait while domoic acid levels dropped or the crab became fuller.

The Oregon Department of Fish and Wildlife said last year’s delayed crab season opening still brought in the second-highest ex-vessel value ever, $66.7 million, with 18.7 million pounds landed, just above the 10-year average.

In central California, crabbers are getting anxious to drop their gear. California Department of Fish and Wildlife Director Charlton Bonham in late November delayed the season until mid-December after a survey showed 49 humpback and four blue whales in the area. A subsequent survey on Dec. 3 showed four humpback whales and one blue whale present in the same survey area.

New Crab Pot Could Help Reduce Whale Entanglements

December 2, 2019 — Oregon’s Dungeness crab season is coming up, but there’s a problem looming over this fishery.

The ropes and buoys that allow crabbers to collect their crab pots from the seafloor can injure and even kill whales when they swim into them.

Last year, 46 whale entanglements were reported off the West Coast, and crab gear was responsible for about a third of them.

According to Derek Orner, a bycatch reduction program coordinator with the National Marine Fisheries Service, this a growing problem in the spiny lobster and Dungeness crab fisheries.

“Were seeing increases in whale entanglements with a number of species that are listed under the National Marine Mammal Protection Act, in particular with humpback whales, gray whales, and blue whales,” he said.

His agency recently announced grants for several ropeless fishing gear projects, including a new kind of crab pot developed by Coastal Monitoring Associates of California.

Bart Chadwick, the company’s president, said when crabbers drop their pots in the ocean, the ropes and buoys can remain in the water column for days.

CALIFORNIA: The secret Richmond lab where Bay Area crab season annually learns its fate

November 29, 2019 — Each year, the fate of Northern California’s Dungeness crab season is in the hands of a few scientists in a quiet East Bay lab examining a small container of tan goo.

At the California Department of Public Health lab in Richmond, the goo is viscera, or the internal organs of a Dungeness crab, and the scientists study it to determine whether a neurotoxin called domoic acid is present.

While the commercial Dungeness crab season is on hold for an entirely different reason — a lawsuit over whale entanglements that postponed the season until Dec. 15 — three of the last four commercial Dungeness crab seasons were delayed after domoic acid, which is poisonous to humans, was found in local crustaceans. The neurotoxin can become present in crabs when algal blooms caused by rising ocean temperatures linger in local fishing waters during crab season. And with California crab fishermen capable of grossing $95 million a year during an uninterrupted season, domoic acid has resulted in tens of millions of dollars in lost revenue.
