Saving Seafood

Diners’ discarded shells help establish new oyster colonies

July 6, 2021 — Call it the seafood circle of life: Shells discarded by diners are being collected, cleaned and dumped into waterways around the country and the world, where they form the basis of new oyster colonies.

One of the latest such projects is taking place in Atlantic City, where a casino and two other restaurants are saving the shells left over from their diners. The shells are then collected by the state Department of Environmental Protection, and workers and volunteers with Rutgers and Stockton universities and the Jetty Rock Foundation load them on barges and dump them into the Mullica River.

That waterway is home to one of the last self-sustaining oyster populations on the Atlantic coast, according to Shawn LaTourette, the state’s environmental commissioner. The clam, oyster and other shells form the basis of new or expanded oyster colonies when free-floating baby oysters, known as spat, attach to the shells and begin to grow on them.

“You have the benefit not only of ecological restoration, but it has kept 65 tons of shells out of landfills,” said Scott Stueber, a fisheries biologist with the DEP. That helps the eateries save on waste disposal costs.

The program began in 2019 and currently collects oysters from the Hard Rock casino, the Knife & Fork restaurant and Dock’s Oyster House in Atlantic City. Several other casinos have expressed interest in joining.

Oyster Farmers Who Feared Going Broke Brace for a ‘Bonkers’ Summer

June 14, 2021 — A year ago, oyster growers who farm New Jersey’s marshy coastal inlets and tidal flats were fighting for survival.

Restaurants were shut down by the pandemic, and the oysters they had nurtured for two years were growing past their prime. The pricey seafood that should have been sold in raw bars or served at weddings was instead submerged in cages and racks in Barnegat and Delaware Bays, crowding out a younger crop of oysters.

“When Covid hit, that market disappeared,” said Tim Dillingham, executive director of the American Littoral Society, a nonprofit dedicated to the study and conservation of marine life and habitats.

Unable to pay for boat fuel or the following year’s seed, some small aquaculture farmers in New York and New Jersey, struggling to revitalize what was once the country’s pre-eminent oyster market, braced for the worst.

But a year later, against long odds, the industry is poised for a summertime boom.

Farmed shellfish creates half of economic impact of shellfish in North Carolina

June 10, 2021 — Cultivated, or farmed, shellfish now represent over half of the total economic impact of shellfish in the state.

New research has found that North Carolina’s shellfish industry provides over $27 million in economic impact and 532 jobs in the state. Until 2016, the industry’s economic impact primarily came from the harvest of wild oysters and clams.

In 2019, farmed oysters contributed over $14 million to state gross domestic product and 271 jobs, according to research published by Eric Edwards of NC State University’s Department of Agricultural and Resource Economics.

The findings stem from a collaborative project led by North Carolina Sea Grant in partnership with researchers at NC State University, Appalachian State University, Duke University and the University of North Carolina Wilmington and funded by the N.C. Commercial Fishing Resource Fund Grant Program.

“The goal of the research was to better understand the economic impact of North Carolina’s seafood industry,” says Jane Harrison, North Carolina Sea Grant’s coastal economics specialist and a project lead. “The shellfish results indicate the strength of the growing aquaculture sector.”

Uneaten oysters provide pearl of an environmental solution during COVID-19 pandemic

June 4, 2021 — Environmental groups and oyster farmers have found a silver lining — or a pearl — amid the ravages of the pandemic.

Millions of oysters that went unsold when restaurants closed are finding a new life back in the ocean, where advocates say they’ll help the environment and help coastal communities combat climate change.

Seafood and shellfish demand crashed during the pandemic. By the time restaurants began to reopen, many oysters had grown too big to eat.

But environmental groups quickly recognized a way to use those oysters in coastal communities. The Nature Conservancy and PEW Charitable Trusts announced plans to buy millions of unsold oysters and return them to the ocean as living reefs.

“We were just sitting on top of these huge oysters, just kept getting bigger and bigger by the day, and we, we couldn’t sell them. So they came in with a program, the SOAR program, and bought a lot of oysters from these guys. And it was a real lifesaver,” said Matt Welling, the owner of Lucky 13 Oysters in Long Island, New York.

UNH scientists aim to solve a million dollar problem for aquaculture industry

May 25, 2021 — A pesky little jellyfish-like animal is causing major problems—and major costs—for aquaculture everywhere by choosing to permanently live on aquafarming equipment, reducing production sustainability. However, new research from the New Hampshire Agricultural Experiment Station in the UNH College of Life Sciences and Agriculture sheds light on possible ways to dissuade these animals at early, larval stage from calling aquaculture production systems home.

The research is vital to NH’s oyster-dominated aquaculture industry, in which the number of farms grew faster than any other state—a 229 percent increase— from 2013 to 2018, according to the U.S. Census of Aquaculture.

New Hampshire had nearly $1 million in sales from aquaculture in 2018. Globally, more than 50 percent of all human-consumed seafood is produced by aquaculture—the farming of fish, mollusks, aquatic plants, and other products. The global economic impact of aquaculture is greater than $31 billion. When post-harvest operations data are included, it is estimated that one in two workers in the sector is a woman.

Paul Simon Galtsoff: Oyster Researcher and Woods Hole Lab Advocate

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

Born in 1887 in Moscow, Russia, Paul Simon Galtsoff was trained at the Imperial Moscow University. He graduated in 1910 with a degree in zoology and chemistry and married Eugenia Troussoff in Moscow in 1911. He soon became one of Russia’s leading scientists. As unrest took hold in the country, he joined the Imperial Russian Army in 1914. The couple moved to Sevastopol where, at age 27, he became the director of the Marine Biological Station, a branch of the Imperial Academy of Science.

Coming to the United States

As the Bolshevik Revolution spread, Paul and Eugenia were forced to leave Sevastopol during “The Great Exodus” November 13-16, 1920 with just hours to spare. Landing in the Port of New York on January 20, 1921, he found that marine research was in its infancy in the United States. With extensive experience in zoology, he eventually found a temporary position with the Bureau of Fisheries. He surveyed the Mississippi River for marine life after construction of a dam in Iowa. Two years later he was appointed to the Woods Hole Lab to serve as naturalist aboard the research vessel Albatross.  

Eugenia had pursued undergraduate and graduate studies in Russia in biology and zoology. After the couple emigrated to the United States, she worked at George Washington University as a histology assistant for many years. Paul Galtsoff pursued graduate studies at Columbia University. He earned a doctoral degree in biology in 1925 while still working at the Woods Hole Lab.

A Sustainable Seafood Sampler from Coast to Coast

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

In the United States, we love our seafood. Thankfully, due to strong science and a dynamic management process, our fisheries are among the largest and most sustainable in the world. So no matter what coast you’re on, you can be sure that the U.S. seafood you find there is a smart choice. And just like the culture of each region has its own flavor, so does its seafood! Read on to discover what local favorites you might find around the country.

Northeast/Mid Atlantic

Eastern Oysters

Farmed oysters are one of the most popular aquaculture species in the world and they’re an excellent choice for your next seafood dish. Oysters filter the water where they live, which removes excess nutrients and improves water quality. Growing oysters also requires no feed since they eat phytoplankton floating in the water. Unlike wild oysters, farmed oysters are available year round. They are low in saturated fat and excellent sources of omega-3 fatty acids and iron.

Oyster flavor profiles can range from sweet to briny. You can eat them raw on the half shell or cook them in a variety of different recipes. They’re delicious whether you grill, fry, broil, or bake them.

Acadian Redfish

Acadian redfish, also called ocean perch, are the only fish in the rockfish/ocean perch family in the Atlantic. The fish is called redfish in New England and Canada—not to be confused with redfish from the Gulf of Mexico (which is a drum).

Acadian redfish are harvested year-round but harvests are usually largest during spring and summer in the Gulf of Maine. Their taste profile is mild and slightly sweet and their meat is medium firm, moist, and flaky.

LOUISIANA: An oysterman’s new worry: Will state’s coastal plan wash out his business?

May 18, 2021 — Sun-kissed lines frame Terry Shelley’s face like high tide stains a fishing dock. Today, those creases seem deepened by anger, but it’s the tone of his voice that gives it away.

Mr. Shelley has spent his entire working life as a commercial fisherman. Before he was a full-time oyster farmer and harvester, he spent the first part of his career harvesting shrimp and reef fish. He’s seen a lot, but not a pileup of challenges like now.

Back in September, Hurricane Zeta rumbled over small-town Port Sulphur, Louisiana, where the family’s oyster farm and processing center are based. The Shelleys lost half their cages, and they only managed to retrieve about half of that. Already by then, the COVID-19 pandemic had temporarily halted the supply lines Shelley Farms uses to sell its oysters.

Now, after losing most of his oyster crop last year, Mr. Shelley has another worry on his mind.

Louisiana coastal planners are pushing a $2 billion project proposal designed to fight back against the trend of persistent coastal erosion.

Mollusks in Oregon coast watersheds contain forestry pesticides, study says

May 11, 2021 — Oysters, estuarine clams and freshwater mussels in watersheds along the Oregon coast contain pesticides used in managing forests, according to a study funded by Oregon Sea Grant.

Researchers from Portland State University found pesticides in 38 percent of the tissue samples. Indaziflam, an herbicide currently used in Oregon forestry, was found in about 7 percent of the samples. Contaminants also included pesticides used in orchards, Christmas tree farms and homes, as well as banned pesticides, including DDT byproducts.

The study, published in the journal Toxics, may help guide forest management practices to reduce the amounts of forestry chemicals entering aquatic ecosystems.

The study was led by Kaegan Scully-Engelmeyer, a doctoral student in the earth, environment and society program at PSU, and PSU marine ecologist Elise Granek.

They collected tissue samples from freshwater western pearlshell mussels — softshell clams typically found in the upper area of estuaries — and Pacific oysters. They collected them from watersheds along the Oregon coast in 2017 and 2018. These organisms are good indicators of environmental contamination because they are sedentary filter feeders.

Ambitious Vision for North Carolina’s Oysters Outlined in New 5-Year Plan

April 29, 2021 — Restoring oysters can boost water quality and offer shoreline protection from storms, and this week the North Carolina Coastal Federation released its five-year action plan, outlining steps to keep this valuable shellfish thriving.

Leda Cunningham, officer for Conserving Marine Life in the U.S. at the Pew Charitable Trusts, said North Carolina’s oysters are in good shape, but face threats from storms, poor water quality and the impacts of climate change.

She believes the new Oyster Blueprint offers an example for other coastal states of how to restore and protect oyster populations.

“In those 15 or so years, it’s led to measurable progress in the state, and that is really a result of the inclusive systematic approach that Coastal Fed has taken with its partners to identify challenges and opportunities with this special resource,” Cunningham stated.

Guided by the Blueprint over the years, North Carolina has restored nearly 450 acres of oyster habitat, grown shellfish aquaculture from a $250,000 to $5 million industry, increased the number of shellfish farms in the state tenfold, and developed a nationally recognized shell recycling program.

Erin Fleckenstein, coastal scientist for the North Carolina Coastal Federation, said the plan includes new management strategies to help safeguard North Carolina’s waters, particularly in the Newport River and Stump Sound.
