New study finds aquaculture could help counter drivers of climate change

January 27, 2022 — A joint study recently released by the University of Adelaide and The Nature Conservancy (TNC), titled “Climate-Friendly Seafood: The Potential for Emissions Reduction and Carbon Capture in Marine Aquaculture,” reveals aquaculture done right could actively reduce the drivers of climate change.

The study assessed greenhouse gas emissions for marine aquaculture of fed-finfish, macroalgae, and bivalves. According to the study, mariculture generates 37.5 percent of all aquaculture products and 97 percent of the world’s seafood harvest. Though mariculture already has a lower greenhouse gas emission footprint than terrestrial products, further low-emissions strategies must be implemented as production continues to scale up to meet future global demand.

Walmart chooses Pacific Island Tuna for its in-house brand

October 6, 2021 — A partnership between the Republic of the Marshall Islands and The Nature Conservancy will supply canned tuna to Walmart stores for the store’s Great Value brand across the United States.

The new joint venture, dubbed Pacific Island Tuna (PIT), is “designed to transform the global canned tuna supply chain,” according to a Nature Conservancy announcement. The new business model is intended to give Pacific islanders the ability to benefit from their tuna resources by directing 100 percent of long-term net profits back to them while utilizing a sustainable model of fishing and production.

MASSACHUSETTS: Oyster Buyback Spawns New Ecology Program in Edgartown

October 1, 2021 — Prior to the pandemic, Ryan Smith, whose Signature Oyster Farm operates out of Katama Bay, sold about 30,000 oysters per week — nearly all of which went to restaurants and raw bars across the Northeast.

By March of 2020, with in-person dining all but completely shuttered, the number dropped to about 300.

“Everything just halted,” the veteran waterman recalled. “I was selling door to door . . . it was terrible. You didn’t know how long it was going to last. But obviously, it lasted a lot longer than anybody could have anticipated.”

And as demand dwindled, the oysters themselves did the opposite, growing too large and gnarled for ritzy raw bars. Farmers like Mr. Smith were left with a fisherman’s catch-22, unable to sell the properly-sized oysters when restaurants closed, and unable to sell the oversized oysters once they reopened.

“I’ve got some that are the size of my boot,” Mr. Smith said. “I’m a size 12.”

Now more than 18 months later, an innovative partnership between The Nature Conservancy and the Martha’s Vineyard Shellfish Group has found a solution, providing a new home for 200,000 overgrown oysters by buying them from Mr. Smith and fellow Katama Bay oysterman Scott Castro at a discounted price and re-seeding them in the Slough Cove section of the Edgartown Great Pond.

New tool maps birds, fish in offshore wind areas

September 23, 2021 — While federal and state officials eagerly pursue a rapid and significant deployment of offshore wind turbines to generate cleaner power along the East Coast, scientists and advocates on Wednesday unveiled a new mapping tool designed to give developers, regulators and the public a better sense of the natural resources below the surface in the neighborhood of proposed wind projects.

Last year, the U.S. offshore wind pipeline grew by 24 percent with more than 35,000 megawatts now in various stages of development, the U.S. Department of Energy said in its latest offshore wind market report. Massachusetts has authorized up to 5,600 MW and so far has contracted for about 1,600 MW of offshore wind power. But even before the first turbine is installed, the industry is facing headwinds from two federal lawsuits that focus on the protection of endangered species like the North Atlantic right whale and commercial fishing interests.

The marine mapping tool rolled out Wednesday by The Nature Conservancy covers the coast from Maine through North Carolina and includes information about the makeup of the seafloor, the fish and invertebrates that live near the bottom of the ocean in a given area, the marine mammals that frequent a chosen swath of ocean, the bird species that are known to be in the area and more. The tool allows a user to compare data from different times of the year and incorporates historical data as well.

Planet Tracker analyst calls for increased observer coverage on distant-water fleet

August 25, 2021 — If one percent of global fisheries subsidies were redirected to onboard monitoring, the proportion of wild-catch fishing monitored by observers could create a meaningful impact in reducing illegal fishing and bycatch, according to Planet Tracker Financial Analyst Francois Mosnier.

Mosnier, a financial analyst covering seafood companies at the financial think tank, said he believes an additional USD 222 million (EUR 190.2 million) is needed to expand observer coverage to 20 percent across all regional fishery management organizations, which cover the cost of observers through a levy on fisheries. Currently, observers cover just 2 percent of all catches recorded by RFMOs.

$900,000 in Funding Recommended for Atlantic Salmon Habitat Restoration

July 30, 2021 — The following was released by NOAA Fisheries:

NOAA Fisheries is recommending nearly $900,000 in funding for four partners to implement projects that restore habitat for Atlantic salmon in the Gulf of Maine watershed. The Gulf of Maine distinct population segment of Atlantic salmon is listed as endangered under the Endangered Species Act. It’s also one of nine NOAA Species in the Spotlight.

Atlantic salmon are an iconic species of the Northeast. They once returned by the hundreds of thousands to most major rivers along the northeastern United States. Now, they only return in small numbers to rivers in central and eastern Maine. These populations comprise the Gulf of Maine distinct population segment.

Proposed projects funded under these partnerships will improve fish passage. They will remove or modify dams, culverts, and other barriers blocking Atlantic salmon from reaching their habitats. They will also restore the structure and function of streams used by Atlantic salmon for spawning and rearing.

We’re recommending nearly $900,000 to fund the first year of four multi-year efforts:

  • The Atlantic Salmon Federation will implement five projects to restore access to Atlantic salmon spawning and rearing habitats in the Kennebec River watershed. They will also conduct a fish passage feasibility study at the Chesterville Wildlife Management Area Dam on Little Norridgewock Stream. ($213,854)
  • Project SHARE will replace undersized culverts at 13 sites, connecting habitat for Atlantic salmon across the Dennys, Machias, Pleasant, Union, and Narraguagus River watersheds. They will also conduct fish passage feasibility studies at the Great Works Dam and at Marion Falls fishway. Funding will also support freshwater habitat restoration work in the Narraguagus River watershed. ($303,225)
  • The Nature Conservancy will complete the final designs to remove Guilford Dam and restore the adjacent floodplain, which will reconnect habitat for Atlantic salmon in the Piscataquis River watershed. They will also restore access to high-quality habitat by improving fish passage at three high-priority road crossings over streams. ($250,000)
  • The Downeast Salmon Federation will support fish passage feasibility studies at the Cherryfield Ice Control Dam on the Narraguagus River and the Gardner Lake Dam on the East Machias River, to support future habitat restoration in these watersheds. Funding will also support fish passage improvements at the Gardner Lake Dam. ($131,000)

Degraded habitat is one of the largest obstacles facing the recovery of threatened and endangered species like Atlantic salmon. Habitat restoration helps repair areas that have been destroyed by development, blocked by dams, or otherwise subjected to habitat destruction. Through funding and technical assistance, NOAA supports projects that restore the habitats that threatened and endangered species need to recover.

Comprehensive global study confirms restorative aquaculture has positive impacts on marine life

June 25, 2021 — The following was released by the University of New England:

The University of New England partnered with The Nature Conservancy (TNC), the world’s leading conservation organization, on a ground-breaking new study that provides strong evidence that shellfish and seaweed farming are a critical component of regenerative food production.

The comprehensive study has been published in Reviews in Aquaculture at a time when much news of food production focuses on its negative impacts on the environment. Quite to the contrary, the study, titled “Habitat value of bivalve shellfish and seaweed aquaculture for fish and invertebrates: Pathways, synthesis, and next steps,” paints a bright picture of aquaculture’s potential to help satisfy food demand in harmony with ocean health.

Restorative shellfish and seaweed farming offers a sustainable method to meet the nutritional needs of the growing human population, while maintaining and improving the health of the waters, lands, and animals we live alongside. This study is among the first to demonstrate the global potential for regenerative outcomes in aquaculture systems.

“Aquaculture is among the world’s fastest-growing forms of food production and there is a growing biodiversity crisis that already exists in our ocean. It’s critical that we identify ways to develop aquaculture that benefits, rather than harms our ocean, that are based on sound science,” said Robert Jones, Global Lead for Aquaculture at The Nature Conservancy. “This study is game changing in that it clearly shows an opportunity through shellfish and seaweed aquaculture. For the first time, we’re able to put quantifiable global numbers on the benefits these farms can have on marine wildlife.”

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.

MASSACHUSETTS: Task force releases report on strengthening shellfish industry

May 6, 2021 — A task force released a series of recommendations this week on how to balance the growing and competing demands for shellfish resources and to strengthen an industry that supports thousands of year-round commercial fishing jobs.

The Massachusetts Shellfish Initiative, led by a 21-member task force, has created a plan that works to maximize the economic, environmental and social benefits of shellfish resources across the state.

“Shellfish play a vital role in our coastal waters,” said Steve Kirk, a task force member and coastal program manager at the Nature Conservancy. “They help improve water quality and provide habitat for other species.”

But climate change is rapidly changing the ocean’s chemistry, Kirk said. When there is more carbon dioxide, the ocean becomes more acidic, which makes it harder for the animals to form their shells, he said.

Ray Hilborn on the role of industry funding

April 12, 2021 — It is true that my research program receives funding from the fishing industry. Industry funding makes up about 22% of my total funding, while I receive similar amounts from environmental foundations, Universities, and private individuals unassociated with the fishing industry. In addition, I receive funding from environmental NGOs, including over the years the National Resources Defense Council, The Nature Conservancy, Environmental Defense Fund, and the Pew Institute for Ocean Science.

Here is my response to those who say this means you should not believe what I say about fisheries:

Science is collaborative, not individual

When I say that all fish will not be gone by 2048 or that fish stocks are increasing in abundance in much of the world, these are not personal opinions, but results of scientific papers authored by a large group of people, each of whom stands by the results of the paper.

When the claim that “all fish would be gone by 2048” came out, the lead author on that paper, Boris Worm, and I agreed to meet together to understand why we had different perspectives. We organized a group of about 20 scientists and looked at trends in fish stock abundance where it was measured and found no sign that these stocks were generally declining. In 2009, we published a paper in Science Magazine showing this, and the lead author was Boris Worm. It is absurd to say that because I, one of 21 authors, had received funding from the fishing industry this work was biased.

I was the first author on the 2020 follow-up paper in Proceedings of the National Academy of Sciences, Effective fisheries management instrumental in improving fish stock status, that showed that fish stocks were actually increasing in much of the world, but this paper had 23 authors, including professors from several different universities, an employee of The Nature Conservancy, a member of the Board of Directors of The Nature Conservancy, a member of the Board of Directors of Environmental Defense, and an employee of the Wildlife Conservation Society all of whom stand by our conclusions. It is not my work, but group work, and where I get some of my funding is largely irrelevant.

Almost every paper with my name on it in fisheries has a range of authors and many of them have at least one author representing conservation organizations.

Look at the data and what was actually done

My research is not cloaked in secrecy. In every research paper I have been a part of, we tell the reader what data we used and how we used it to get the results we did. This is the methodology section. We describe our data and methods so you, or anyone else, can redo and/or verify the analysis.

This is an important part of science. I have criticized the methodology section of others before, and others have criticized mine—this is what makes information evolve closer to truth. Unfortunately, that part of science gets lost in press releases and hyperbolic headlines, which was a large reason I started this website—to explain the methodology sections of important fisheries papers to give the public (and journalists) proper context. For example, we have been highly critical of Oceana’s seafood fraud methodology on this website, but we appreciate the work they do and gave them a platform to respond to our criticism.
