Saving Seafood

Clammers digging through pandemic, but shellfish are fewer

April 19, 2021 — Chad Coffin has spent the coronavirus pandemic much as he has the previous several decades: on the mudflats of Maine, digging for the clams that draw tourists to seafood shacks around New England.

But he’s running into a problem: few clams.

“There just isn’t the clams that there used to be,” Coffin said. “I don’t want to be negative, I’m just trying to be realistic.”

It’s a familiar problem experienced by New England’s clamdiggers. More New Englanders have dug in the tidal mudflats during the last year, but the clams aren’t cooperating.

The coronavirus pandemic has inspired more people in the Northeastern states, particularly Maine and Massachusetts, to dig for soft-shell clams, which are also called “steamers” and have been used to make chowder and fried clams for generations. The era of social distancing during the coronavirus pandemic is conducive to the often solitary work, said Coffin, the president of the Maine Clammers Association, which represents commercial clammers.

But the U.S. haul of clams has dipped in recent years as the industry has contended with clam-eating predators and warming waters, and 2020 and early 2021 have been especially difficult, industry members said.

How much is a clam worth to a coastal community?

February 25, 2021 — Researchers have developed a method to estimate the value of oyster and clam aquaculture to nitrogen reduction in a coastal community. Nitrogen is a nutrient that comes from many different sources, including agriculture, fertilizers, septic systems, and treated wastewater. In excess it fuels algal growth, which can affect water quality and human health.

As a result, a growing number of communities are required to follow regulations to reduce the amount of nitrogen they release. Shellfish are an option that can be a valuable part of a community’s nutrient management plan.

In a study in Environmental Science & Technology,  biologists, economists, and modelers from NOAA Fisheries, NOAA National Centers for Coastal Ocean Science, and Stony Brook University used a transferable replacement cost methodology to estimate the value of oyster and clam aquaculture to nitrogen reduction in Greenwich, Connecticut.

Growing bivalve shellfish, including oysters and clams, provides direct economic benefits to a community by supporting jobs and making fresh local seafood available to consumers. It also provides ecosystem services—benefits that nature provides to people—including habitat for native species and improved water quality.

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.
