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.

CALIFORNIA: Bay Area crab sellers dismayed over delay of commercial Dungeness season

November 25, 2019 — Marin’s fishmongers reacted with both disappointment and understanding to news that Northern California’s commercial Dungeness crab season has been delayed again.

The state Department of Fish and Wildlife confirmed Friday, after issuing a preliminary announcement earlier this week, that the opening has been held back until Dec. 15 in an effort to prevent whales from getting tangled in fishing lines.

The season had already been delayed a week from the traditional Nov. 15 start date over concerns about whale entanglements.

Responding to concerns from the commercial crab fleet, state Fish and Wildlife Director Charlton H. Bonham announced late Friday that he intends to further delay the commercial season south of the Mendocino/Sonoma county line.

CALIFORNIA: Dungeness crab season pushed back over whale concerns

November 22, 2019 — Bay Area crab connoisseurs will have to wait until next month for a taste of Dungeness crab, as the California Department of Fish and Wildlife has once again pushed back the start date of the commercial season.

The commercial Dungeness crab fishery south of the Mendocino/Sonoma County line was set to open on Friday, however, it will now open on Dec. 15 in order to minimize the risk of whales getting entangled in ropes connected to crab traps.

The new date comes after an aerial survey on Monday conducted by the CDFW, the Greater Farallones and Monterey Bay national marine sanctuaries, which found concentrations of whales near Point Reyes and Half Moon Bay.

According to CDFW officials, another aerial survey will be conducted ahead of the new start date to again evaluate whale presence in the area and determine if there’s any further risk to marine life.

The commercial Dungeness crab season was originally set to start last Friday but earlier this month the California Department of Fish and Wildlife announced the start date would be moved by a week out of fear that whales and sea turtles might be harmed.

Dungeness crab season postponed in multiple US states

November 18, 2019 — The U.S. West Coast Dungeness crab season has been postponed in multiple states for a variety of reasons.

Last week in California, the Fish and Wildlife Department decided to postpone the start of the season for fishermen south of the Mendocino/Sonoma County line from 15 to 22 November, citing the threat of sea turtle and whale entanglements, according to The Daily Democrat. Data showed that whales were migrating through the area and the delay was enacted out of an abundance of caution.

OREGON: Officials delay the Dungeness crab season, crabs aren’t big

November 15, 2019 — Traditional Christmas feasts featuring Dungeness crab may not be in the cards this year as officials have delayed the commercial crabbing season due to the small size of the crustaceans.

The Mail Tribune reports that the season had been set to start Dec. 1 for Oregon’s most lucrative commercial fishery, but now crabbing has been postponed until at least Dec. 16.

It’s the sixth straight year the season has been delayed to allow the Dungeness crabs a chance to fatten up to meet industry standards.

Dungeness crab fishing season delayed due to whale and sea turtle entanglement risk

November 12, 2019 — State Fish and Wildlife officials are delaying the start of the Dungeness crab fishing season due to a threat of whale and sea turtle entanglements.

Charlton Bonham, director of the Fish and Wildlife department, issued a decision to postpone the start date for California Dungeness crab fishermen south of the Mendocino/Sonoma County line for one week — from Nov. 15 to Nov. 22. The decision was based on data indicating the prevalence of whales in the area.

Bonham’s decision to minimize entanglement risk follows a court-approved agreement with the Center for Biological Diversity, a Phoenix-based environmental nonprofit that in 2017 sued the wildlife agency, claiming it had fallen short in preventing Dungeness crab fishing gear from killing humpback, blue whales and leatherback sea turtles. Fish and Wildlife is responsible for granting the fishery its permits.

Bonham originally delayed the start of the season until Nov. 23, but moved it up one day after receiving input from the California Dungeness Crab Fishing Gear Working Group. The group, made up of commercial and recreational fishermen, environmentalists, members of the disentanglement network, and state and federal agencies explores ways to minimize whale entanglements in crab fishing gear.
