MASSACHUSETTS: Panel: ocean acidification threatens shellfish sector

February 12, 2021 — As a result of climate change and direct human factors, the waters of the Atlantic Ocean off Massachusetts are becoming more acidic, making them a less friendly habitat for the shellfish that drive a key industry here.

With no action, many of the scallops, clams, mollusks and lobsters at the bottom of the ocean in the Gulf of Maine will begin to dissolve by 2060 and new ones will struggle to form, imperiling an industry that supports thousands of people in the Bay State, a special commission said in a report Tuesday.

The Special Legislative Commission on Ocean Acidification recommended that Massachusetts establish a broad ocean acidification monitoring system and funnel more money into existing programs that address some of the things that are making the ocean more acidic, like residential and agricultural runoff, septic discharges and the deterioration of natural wetlands.

MASSACHUSETTS: Panel: Ocean acidification threatens lucrative shellfish sector

February 10, 2021 — As a result of climate change and direct human factors, the waters of the Atlantic Ocean off Massachusetts are becoming more acidic, making them a less friendly habitat for the shellfish that drive a key industry here.

With no action, many of the scallops, clams, mollusks and lobsters at the bottom of the ocean in the Gulf of Maine will begin to dissolve by 2060 and new ones will struggle to form, imperiling an industry that supports thousands of people in the Bay State, a special commission said in a report Tuesday.

The Special Legislative Commission on Ocean Acidification recommended that Massachusetts establish a broad ocean acidification monitoring system and funnel more money into existing programs that address some of the things that are making the ocean more acidic, like residential and agricultural runoff, septic discharges and the deterioration of natural wetlands.

“Ocean acidification poses a serious threat to the Massachusetts state economy, and a potentially existential threat to coastal economies that rely heavily on shellfishing,” the commission wrote in the conclusions of its report. “Massachusetts should act to combat ocean acidification now, rather than later. Ocean acidification is expected to worsen significantly before the end of the century. Actions taken now will ultimately be more cost-effective and valuable than actions taken when significant damage has already occurred.”

Global carbon dioxide emissions absorbed by the ocean and nutrient pollution of waterways drive the pH level of areas of the ocean down, making the waters more acidic and limiting certain ions that help clams, oysters, scallops, mussels and lobsters form their protective shells.

MAINE: New England clammers press through pandemic

September 8, 2020 — For New England’s vanishing commercial clam harvesters, the coronavirus pandemic represents only the most recent in a string of setbacks that have held down the centuries-old industry.

The clamdiggers, who pull softshell clams for use in chowders and clambakes from tidal muck, have weathered an aging workforce, relentless predators that eat shellfish, warming waters and fickle markets. This summer’s pandemic has held back few of the clamdiggers from plying their trade in the coastal clam flats that have fed their customers for generations, members of the industry said.

Buyers have rewarded the clammers with prices that have held up better than many sectors of the beleaguered seafood industry, which has suffered a significant economic hit from the pandemic. But some clammers said the disruption wrought by the pandemic has still created yet another difficulty to deal with.

“If they shut down the borders now, like they did before, we’d be in some big trouble. We rely on shipping,” said Wendell Cressey, a Harpswell clammer. “Not only do we need the tourists to be able to come here and visit, but we need to be able to ship them around the country.”

As the world’s population grows, researchers say the ocean and seafood have big roles to play

August 27, 2020 — Seafood production could see as much as a 75 percent leap over the next three decades if certain policy reforms and technological improvements are put in place, according to research conducted by Oregon State University (OSU) in collaboration with a bevy of international scientists.

By 2050, the earth’s human population is expected to reach 9.8 billion, an increase of two billion people over the current global tally. Researchers, who published their latest findings in Nature, believe that seafood has the potential to feed the growing world over the next 30 years sustainably – if certain conditions are applied.

Ocean Acidification Threatens Bivalve Industry

July 9, 2020 — Worldwide, ocean levels are rising at an accelerated pace. Cape May County is feeling the effects of exacerbated weather events, as a result.

Yet, there is another drastic change affecting the oceans – a decrease in the water’s pH levels. This is a change that industry leaders and scientists fear will drastically affect the county, namely its bivalve (aquatic invertebrates with a hinged shell) industry that is, as marine and coastal sustainability expert Dr. Daphne Munroe said, “At the heart of the economy in this region.”

As carbon is released into the atmosphere, it was once speculated that the ocean’s tendency to absorb emissions would be a net positive, as it spared the Earth’s atmosphere from the worst of the emissions. Dr. Feely, senior scientist at National Oceanic and Atmospheric Administration (NOAA), said, “[It’s] a huge service the oceans are doing that significantly reduces global temperature.”

However, scientists are coming to realize that the ocean’s absorption of carbon emissions comes at a great cost, and that the long-term effects of an ocean that has absorbed great amounts of carbon emissions mean that ecosystems will ultimately suffer.

Partnerships Improve the 2020 Atlantic Surfclam Stock Assessment

June 23, 2020 — The following was released by NOAA Fisheries:

Atlantic surfclams live at depths between 20 and 35 meters, with an optimal temperature range of 16 to 22o C. They are managed as one stock, with two biologically distinct areas. Surfclams in the northern area on Georges Bank are faster growing than southern surfclams, and the populations don’t mix.

Thirty years ago, southern surfclams grew faster than they do now, and lived in shallower waters. They were also bigger than the surfclams on Georges Bank. Now, these dynamics are reversed. Surfclams in the southern areas have moved to deeper waters, and grow more slowly, to a smaller maximum size. These population changes have been observed by fishermen, noted in their logbooks, and appear in research survey data.

In recent assessments, scientists treated the two areas separately, each with its own assessment model. This time, there is one model with two areas. Dan Hennen, lead surfclam assessment scientist at the Northeast Fisheries Science Center, developed this model. He collaborated closely with the surfclam industry and academic partners, like the Science Center for Marine Fisheries, a National Science Foundation Industry/University Cooperative Research Center.

Working together led to a two-area model, which better deals with the challenges of a population with changing dynamics. Understanding how growth is changing led to better diagnostic behavior in our model. This gives fisheries managers more confidence that it accurately reflects what is going on in the population.

RHODE ISLAND: Virus puts freeze on demand for shellfish

April 3, 2020 — Jody King’s hands usually dry out from salt water after a day of work on Narragansett Bay, where he rakes quahogs for a living from the sandy bottom around Prudence Island.

Now, King’s hands dry out from using too much Purell.

His last day of steady quahogging was more than a week ago, when his dealer called to say he couldn’t buy any more clams. These days, King sits at home, waiting for a call to return to work.

With restaurants shuttered and fish markets in Boston, New York and other East Coast cities closed because of the spread of coronavirus, quahoggers like King have been left with no demand for their product.

“The bay is open, and I can’t go to work,” said King. “This is an absolute first.”

Andrade’s Catch in Bristol usually buys 4,000 to 6,000 clams a day from quahoggers, but after the wholesale business collapsed the shop could only move 1,000 pieces a day selling retail to locals.

“We could make it another month, a month and a half like this, but the fishermen are really at risk,” said Davy Andrade, a part-time owner of the shop. “It takes about $200 a day to run a boat and pay the bills and feed their family, and these guys are pulling in $100 a day if they’re lucky.”

NOAA Fisheries Announces Final 2020 Atlantic Surfclam and Ocean Quahog Commercial Fishery Specifications and Minimum Size Suspension for Atlantic Surfclams

February 13, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries is implementing surfclam and ocean quahog quotas for the 2020 fishing year that we previously announced as projected on February 6, 2018. There have been no overages in 2019, and there is no new biological information, so we are now finalizing the 2020 quotas. The 2020 fishing year quotas will remain 3.4 million bushels for surfclams, 5.33 million bushels for ocean quahogs, and 100,000 Maine bushels for Maine ocean quahogs.

NOAA Fisheries is also suspending the minimum size requirement for surfclams. Discard, catch, and biological data show that 22 percent of 2019 coastwide landed surfclams had a shell length less than 4.75 inches, which is less than the 30 percent trigger for a minimum size requirement. This is closer to the trigger than in prior years. Vessels are encouraged to avoid areas with a lot of clams under 4.75 inches to reduce the chance of initiating the default minimum size in 2021.

NEFMC Reviews Great South Channel HMA Research Proposal; Receives Wind Updates

January 30, 2020 — The following was released by the New England Fishery Management Council:

The New England Fishery Management Council discussed several offshore wind and habitat-related issues during its late January meeting in Portsmouth, NH, including a proposed exempted fishing permit (EFP) for the Great South Channel Habitat Management Area (HMA) that would allow surfclam and mussel dredging within a defined portion of Rose & Crown – one of the HMA’s research-only areas.

The HMA was created through the Council’s Omnibus Essential Fish Habitat Amendment 2, which was implemented April 9, 2018. Surfclam dredge vessels were granted a one-year exemption to continue fishing in the area. The exemption expired April 9, 2019.

The Council developed a Clam Dredge Framework as a trailing action to the amendment to consider allowing the use of clam dredge gear and, subsequently, mussel dredge gear within the HMA if the gear could be used without harming sensitive habitat.

Microplastics in vast majority of Oregon shellfish, study finds

November 13, 2019 — A Portland State University study found tiny pieces of plastic in the vast majority of razor clams and oysters sampled along the Oregon coast and noted that the primary source of contamination was from fibers used in synthetic textiles.

Those microscopic fibers can be shed by yoga pants, fleeces and other active wear made of synthetic textiles during a wash — up to 700,000 per load of laundry, according to the study, which was reported on Tuesday in The Oregonian/OregonLive. These fibers are in the wastewater from laundry machines that eventually winds up in the ocean, although some of the tiny plastic fibers could also come from derelict fishing gear, the newspaper said.

The shellfish in question were plucked from 15 sites, from Clatsop in the north to Gold Beach near the California border, in both the spring and summer of 2017. Of the roughly 300 shellfish analyzed, all but two contained at least some microplastics, Elise Granek, a PSU professor of environmental science and management, said.

The study was published in the journal Limnology and Oceanography Letters.
